Why is the file size increasing when cropping in Photoshop CC?

While cropping a picture the file size is increasing dramatically.
An image 7360 X 4912 px (Image size : 103,4M) after cropping to 60 X 40 cm 300 px, goes up to an image of 18000 X 12000 px (Image size : 618,0 M). And the computer is unable to cope with such a file...
It wasn't like that when I first started to use the program.
I crop the same image using CS5 and the result is an image of 7087 X 4724 px (Image size : 95,8 M) which is normal...
Will aprreciate help...

Thanks for replying. First I didn't have this problem in the beginning. I do the same in CS5 and I can do it with no problem.

The FIle Size increase when I transfered to another external...why?

I just bought a new external hard drive to replace my old external. After copying all my folders and what not to the new hard drive, i noticed that some of the file sizes weren't the same as before. Yet everything looks like it copied correctly.
Example:
Video folder on old HD = 5.6 GB
Video folder on new HD = 10 GB
Is there a logical reason for this and should I be concerned?

I believe that your issue is because the block (cluster) size on the disks is vastly different. Blocks are essentially the smallest amount of disk space that can be allocated to hold a file and a file takes up a least one block. If the file is bigger than the block size by even a single byte, it spills over and occupies a second block, even if it doesn't use the full second block. Thus, you get wasted space when the file size isn't exactly the same as a multiple of the block size.
For a FAT32 formatted disc, your default block/cluster size is either 16KB or 32KB, but for Mac OS Extended, it's 4KB. So, you're going to waste quite a bit more space on the FAT32 drive because its default cluster size is quite a bit larger than the equivalent on Mac OS Extended.

Why is image file size increasing when changed to CMYK?

When converting the colour of a Jpeg to CMYK in Photoshop CS5 the file size is increasing.
The original image is 352KB and after saving as CMYK it is 2.1MB
Why is this happening and how can I stop it?
I'm using a lot of images for a print project so need to keep file sizes small with resolution of 300dpi. The image dimensions are really small, only about 30mm high so they shouldn't be this large a file size
I am using a clipping path but this doesn't seem to be effecting file size (I checked by saving it as RGB with a clipping path which stayed small, and by saving one without a clipping path in CMYK which was huge)
Thanks

Two things may be happening:
1)      you may be making the file pixel dimensions (width and height) larger due to the 300 dpi requirement.
2)      CMYK files, with 4 colors per pixel, are expected to be larger than JPG files, which are 3 colors per pixel and the data is compressed in a way that throws away information.
You will not get CMYK files anywhere near as small as JPG files, as you are finding.   If there are compression options available when you save the file, perhaps those can make the files smaller.
What pixel dimensions is the original JPG and what pixel dimensions are the CYMK files?

Why does the file size change when put into an iDVD project? And problems with dual layer discs...

I exported a short video of mine from Final Cut Express and the size of the file came out to 7.3 GB. When I put it into an iDVD project, it says that the file is only 800 MB. I tried just burning it onto a dual layer disc anyway to see if it might still burn at the original file size, but the disc came out unusable for some reason, and obviously hadn't been burned anywhere near full-capacity. So, I tried it again, and the exact same thing happened.
I guess my first question is: why is iDVD changing the size of the file? I want the quality to be the best it can be, so keeping it at 7.3 GB as opposed to 800 MB is rather important.
Secondly, why did the dual layer discs come out unusable? I've burned single layer discs before and they haven't been an issue. Also, I know for a fact that the drive can burn dual layer discs, so that isn't the issue.
Thanks in advance to anyone who can provide me with help on this issue.

Guessing here but it looks like you edited/exported an SD/DV sequence of about 30 min in FCE. DVD needs to be MPEG-2 so iDVD compresses the original file down to the size that you report.

The quality will be what the MPEG-2 compression and the software allow for. MPEG-2 is DVD standard .... there's no way around that.

Guessing again but it would seem that you burned a Data DVD instead of a Video DVD which would be unusable by a set-top player. As I said above you can't get around DVD standards.
If by any chance your video was HD originally you can try to go the Blu-Ray route using Roxio Toast or FCS 3 (discontinued) or FCP X. You will also need a Blu-Ray burner.

When I narrate my keynote presentation, why is the file size so huge?

When I narrate my keynote presentation, why is the file size so huge?

Here are the steps so you can see all the files that make up your Keynote…
Go to the Finder and find your Keynote file and make sure that it has the .key extension on it. If it doesn't, click it and command i to view info and uncheck the box that says Hide Extension.
Delete the .key and change to .zip and then click the use .zip in the dialog box that comes up
Double click the new .zip file and it will change it to a folder
Open the folder there are the files
Close the folder and add .key to the end of the name and click Add in the dialog box (this will change it back to a Keynote file)
You might be able to do this and convert the voice narration to a smaller format.

Why does PDF file size increase each time I "save" tagging tasks?

Why does PDF file size increase each time I "save" tagging tasks?
Given:
1) I'm running Acrobat Pro 11.0.07 (this is most current version)
2) My file size starts at 750mb and ends up 15mb when finished tagging.
3) Only certain documents experience this increase, i.e., no visible pattern of document characteristics
4) PDF's are not full of images...in fact, mostly <H1> <H2> <H3> <P> <Figure> alt text, ect.
5) Occurs with text PDF's and/or fillable forms (again, does not happen to all documents...only some)
6) File increase occurs incrementally as tagging tasks are performed; i.e., each new save increases file size a few megabytes.
7) Occurs whether I "save" or "save as"
8) Difficult to optimize these files without corruption
9) I'm running Mac OS 10.9.4 (this is most current version)

Thank you so much for responding! I've been experimenting with the SAVE AS vs. SAVE for the past few days...and you are correct. It's funny because I've been tagging files for 2 years and never noticed this. Probably b/c I use both methods depending on the tagging tasks...some are more complicated than others and should not be overwritten. In those cases I SAVE AS new file.
I love this forum...thank you again!

Why Such a Huge Photoshop File Size Increase When Saving In CC from other versions?

Hello,
I have limited experience in Photoshop, and am working with a file with two other people. We are creating web comic pages. The line artist and colorist are both using CS 6. I have CC. The file I receive from them is around 238MB. If I open it and make even the slightest edit, Photoshop will not save it as it warns that the file size is too large (greater than 2GB!). How does this happen? Is it something in my preferences that causes 10x increase in file size?
Any help is appreciated.
Thanks!

Thanks for replying. First I didn't have this problem in the beginning. I do the same in CS5 and I can do it with no problem.

How can I keep the file size small when I render a .mov file to video in PS entended CS4?

Hi,
I haven't worked with video in Photoshop before and I am having the following issue:
I imported a .mov file into photoshop. I trimmed the file by moving the start and finish points to the relevant points on the timeline. I then cropped the image to get rid of unwanted footage on the edge of the screen. I then selected export - render video. On the panel I chose to select only "currently selected frames" as the range and I chose "Quick Time Movie" as the file type. When I check the properties of my newly rendered movie the file size has increased by several times. The file sizes are now much too large.
I know that I must need to alter some of the render settings but having tried altering many of the settings the result is always the same - a very large file size that is much bigger than my oringinal file.
If anyone can let me know how I can carry out a simple crop & trim on a .mov file and end up with a smaller more compact file after rendering the video I would really appreciate it. Thanks in advance!

Hi Marion,
Thanks very much for your message. I have downloaded that program and it's definitely handy for examining the details of the original file. You mentioned in your message about not having to recode the file - The file I'm editing is originally from a Q3 Zoom video recorder and I can use their in-built software (handyware) to trim the file - this doesn't recode the file and so the file size just reduces by the required amount. Unfortunately there is no facility to crop the file with this software - I've looked for other software that would allow cropping without having to recode the file but I haven't found anything suitable for a simple procudure like this - do you know of any software that allows you to crop a file without recoding? Thanks.

Why are the file sizes of exported jpegs so small?

I shoot raw, studio portraits mostly. I import to Lightroom 5 as DNG and then edit. Upon exporting as jpegs, the file sizes end up way too small, some of the cropped and/or black & white conversions as small as 560 KB, even with slider to 100%. Un-cropped color photos are ending up from 1.5 to 3MB. What am I doing wrong?

Jim,
Thank you for your response. I think some of the difficulties in this thread are that there have been more than one person reporting issues, which may or may not be exactly the same or different from the initial one reported by the original poster. Then, anyone else commenting can easily intermix bits and pieces from any or all of the other posters interrelated issues. Also, I should have added to my last response in clarification what I meant about the overall dimensions. I was referring specifically to inches, not file size, not resolution.
My very first post was a thank you to Rusty's post for his comment about how he had noticed his Resolution setting had been changed from ppi to ppcm. I didn't say anything about printing. In fact, I never even stated what my issue was. I was merely thanking him for sharing information. So, for anyone to tell me that I didn't know what my issue is, that I didn't understand was quite laughable to me. And then the other two posters were almost equally ridiculous, who said that since they didn't experience the same conditions as myself and another person, it couldn't be a programming error.
Trust me, I understand explicitly about resolution, image size, dimensions, file size and how they are all interrelated. Resolution is essentially the density of pixels. (And I'm still used to dpi vs ppi, that's how long I've been working with the concept.) I often help other people understand in whichever mode is most comfortable for them to grasp the knowledge of how to know what size image they need/want to capture and print depending on the types of measurements shown on their equipment used and by whomever they might be working with for finish work.
I have a set process, I have set image sizes, I have an action recorded in Photoshop to shrink my images to 24" x 36" and save them in the proper folder with the proper name and another to shrink them to 8" x 12" and place them in the proper folder with the proper name. I am meticulous, so when the first image imported into Photoshop and it was 18.898" x 28.346", un-cropped, I couldn't figure it out. The file size was still just as large, the resolution was still 72, I hadn't changed any settings in Lightroom or Photoshop, the ONLY thing I had done was install an update. It didn't make sense to me that with the pixel dimensions still being the normal size, all of the sudden the inch dimensions were smaller. And I did need to be able to have the capability for a larger print size if/when I do want to print.
I hope that I'm being clear now. I really was just trying to post a thank you initially. I hadn't expected all of this excess.
I apologize for the troll statement. It wasn't meant for you directly, it was more for the grouping of comments which in my opinion didn't seem to be useful for the discussion and were instead just baiting. I shouldn't have allowed my bad mood to permeate my own comment regardless. I am also sorry for any other statements I made which might have come across wrong. I was trying to be funny with my first comment about programmers, but it might not have come across that way. I hadn't expected the rude and unnecessary comment back which I received, and that's where the trollish comments came from. That's why I only responded to that person once, despite the string of poking posts.

PDF file size increases when I add a Email Submit button

Hello,
My PDF form is 87KB. Once I add a Email submit button the file size jumps to 525KB. Why?
Reason this confuses me is that it seems to be inconsistent. I have added this function to other PDF forms and the file size only increased a few KB. Every now & then adding a button or Javascript will increase the file size.
I have retraced my steps over & over, but I cannot find a answer to why this is happening.
Thanks for the help everyone!

The problem is the font. Use Helvetica instead. When you do, Acrobat/Reader actually use a version of Arial anyway.
When you use one of the non-base-14 fonts (Helvetica, Times, Courier, [and their bold, italic, bold italic variants] Symbol, and Zafp Dingbats) for a form field, Acrobat has to embed the entire font in the file, and some can be rather large. The base-14 fonts are guaranteed to be available for use by the compliant PDF viewer, so there is not need to embed them in the file. A viewer is allowed to substitute suitable replacement fonts, which is what Acrobat/Reader now do.
The problem is you can't simply go back and change the font to Helvetica and see the full size reduction that you'd expect after you do a Save As. This is because Acrobat does not clean up everything as well as you might expect. So what you have to do is go back to a version of the form that does not have the button, or copy & paste the field from the old form to a new PDF that doesn't have any fields, but delete the button first. Then create the button anew.

Pdf file size increases when printing resulting in slow print speed.

I have a .pdf that is saved at 27MB. When I send it to an HP Designjet T520 36in printer the file size jumps up to 136MB and the printing is incredibly slow. This does not happen on all files on a few random ones. Any ideas on how to resolve this issue?

It's entirely normal for file size to increase. PDFs are much more compressed than print streams. For some printers the print size is almost constant (a huge bitmap), for others, it's a collection of graphical items and the size varies enormously. Rarely anything you can do.

Why is the file size so small?

Why is a certain file of about 40 MB that I created, possibly with InDesign CS2, reduced to about 6 MB when I open and rename it using "save as" in InDesign CS4? The 40 MB and 6 MB versions both look identical on the screen and when printed. This just recently happened with one particular file, but not with a similar file. They both contain numerous linked Photoshop images.
I understand that using "save as" deletes possible "undo's" and can reduce the file size. Also, the newer version of InDesign could create a smaller file. But 85% smaller? And why no significant reduction in a similar file.
I don't imagine you often hear complaints about files being too small, but this really has me confused. Anyone ever heard of a similar problem?

Many applications do a "fast save". This includes Acrobat and Word for example. The quick save writes new stuff to the end of the file, making the file larger every time even if you delete things. Some apps use "Save as" to go through and do a slower save of only the things still used. I don;t actually know if InDesign works this way but it's quite likely. Fast save also has the advantage that it's much less likely to corrupt the file you are overwriting.

File size increases when I export from iphoto

I was hoping someone could help me. When I export an event from iphoto it increases in size and is now too big for my dvd. In iphoto, the size is 5.9 GB, but then when I export (settings as follows: JPEG - Max. - Full Size ) the file is too big to burn on my DVD-RDL (8.5GB)
It goes from 5.9 to 10.48 GB.
Any thoughts?
Thanks!

Most Simple Back Up
Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
Slightly more complex:
Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically. Examples of such apps: Chronosync or DejaVu . But are many others. Search on MacUpdate
I'm Serious about Back Ups. And you should be too.
My Library lives on my iMac. It’s Backed up to two external hard disks every day. These disks are permanently attached to the iMac. These back ups run automatically. One is done by Time Machine, one is a bootable back up done by SuperDuper
It’s also backed up to a portable hard disk when ever new photos are added. This hard disk lives in my car. For security, this disk is password protected.
I have a second off-site back up at a relative’s house across town. That’s updated every 3 or 4 months.
My Photos are backed up online. There are many options: Flickr, Picasa, SmugMug etc. However, check the terms of your account carefully. While most sites have free uploading, you will often find that these uploads are limited in terms of the file size or the bandwidth you can use per month. For access that allows you to upload full size pics with no restrictions you may need to pay.
Every couple of months I test the back ups to make sure they are working correctly. It’s very easy to mis-configure a back up application, and the only way to protect against that is to do a trial restore.

Why is the file so large when I record from the microphone?

I am trying to write a program that will save incoming and outgoing voicestreams while playing them. I have been successful thus far but when I record the voice from the speaker(microphone) the file size is in the Megabyte size within a few seconds of recording! The incoming stream is more acceptable in size. I checked the files the incoming stream is 128kbps while the microphone recording is 1411kbps. I tried setting the restriction on the devicelist but that didnt work.. any ideas?

I am trying to record the outgoing voice stream when i speak into microphone to another person. I used mostly the AVTransmit 2 code to do that. The thing is i get "no processor exception" when I try to clone the data that i get from processor.getOutput. But if i were to clone the dataSource that is directly from the microphone before being processed then it works but with a much larger file size at 1120kbps. The thing is I am processing the cloneableDataSource so i am not sure what went wrong

Why the files my program create are created twice each file double ? And why sometimes the files size are too small ?

My program is using Queue of type Uri to create Queue of urls and then i'm using webbrowser to navigate each Uri from the Queue in it's turn and get the url(html) source content and save it to the hard disk.
The problem is sometimes the text files on the hard disk are small like 90KB or 60KB and sometimes they are as they are suppose to be 300KB or 200KB.
This is a button click event where i'm calling two methods:
private void toolStripButton3_Click(object sender, EventArgs e)
GetHtmls();
CheckQueue();
This is the GetHtmls method code:
private Queue<Uri> myUrls = new Queue<Uri>();
private bool isBusy = false;
private void GetHtmls()
for (int i = 1; i < 49; i++)
adrBarTextBox.Text = sourceUrl + i;
targetHtmls = (combinedHtmlsDir + "\\Html" + i + ".txt");
Uri targetUri = new Uri(sourceUrl + i);
myUrls.Enqueue(targetUri);
sourceUrl contain website address: http://www.tapuz.co.il/forums2008/forumpage.aspx?forumid=393&pagenumber=
And i'm adding to it the numbers and create the pages.
And add them to the Queue.
THen the CheckQueue method:
Uri uri;
private void CheckQueue()
if (isBusy)
return; // We're downloading some page right now, don't disturb
isBusy = true; // OK, let's get started
if (myUrls.Count == 0) // No more pages to download, we're done
isBusy = false;
return;
uri = myUrls.Dequeue(); // Get one URL from queue
getCurrentBrowser().Navigate(uri);
It suppose to Navigate to each Uri(html address) in the Queue.
And the browser document completed event:
private void Form1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
// If page loaded completly then do something
int urlnumber = uri.ToString().IndexOf("pagenumber=");
string number = uri.ToString().Substring(urlnumber + 11);
int num = Int32.Parse(number);
targetHtmls = (combinedHtmlsDir + "\\Html" + num + ".txt");
StreamWriter writer = File.CreateText(targetHtmls);
writer.Write(getCurrentBrowser().DocumentText);
writer.Close();
isBusy = false; // We're done
CheckQueue(); // Check next page in queue
In the completed event i'm getting the page number and build the string for the text file then write the html source content to the text file.
In the end i have on my hard disk 48 text files.
The problems are:
1. Sometimes it seems like it's not finishing navigating to the current uri or maybe some other reason maybe server side problem and creating small size files with source content inside but not all the source content. Sometimes the text files size are each
file 99KB or 70KB and sometimes the size of them are about 300KB and 200KB and this is the right sizes 300KB 200KB.
2. The text files on my hard disk suppose to be 48 different files each file should contain the source if the html page of the 48 pages. But on my hard disk the 48 text files are duplicated for some reason.
This is the file on my hard disk:
Some of the files are 205KB 350KB 175KB and some of the files sizes are 85KB 94KB 35KB
Why some of the files it didn't navigated to the end or maybe didn't got all the source ?
And why it's making each second file the same like the one before ? It suppose to create 48 different files but i'm getting two identical files each navigation.

I solved it now.
This is what i did:
It's a bit slow process since i'm waiting for each page to be loaded into the webbrowser but it does the work.
