Do Leopard icons increase the file size?

In programs like Photoshop you have the option of including a preview or a thumbnail icon for the image you’re saving. This is important to know because, if you are making a web page or trying to fit as many files as possible on a disk, you want the file sizes to be as small as possible, and you do not want the images saved with a thumbnail icon or preview.
In Leopard, in list and icon views, I noticed that the files have an icon whether you had these settings turned on in Photoshop or not. How does this work? Are those icons in the finder being embedded into the file or is Leopard some somehow generating them “on the fly” and not increasing the file size of the individual images? Does Cover Flow work the same way, and generate the previews on the fly rather than embedding anything into the images?

Unless you've given a file a custom icon, through the Finder, Photoshop, or another method, the icons are generated elsewhere in the system and aren't part of the file itself.

HT4863 How can I increase the file size limit for outgoing mail. I need to send a file that is 50MB?

How can I increase the file size limit for outgoing mail. I need to send a file that is 50MB?

You can't change it, and I suspect few email providers would allow a file that big. Consider uploading it to a service like Dropbox, then email the link allowing the recipient to download it.

Why is that saving as PDF increase the file sizes?

Hola
I've been notice that when I save a file as PDF, in CS5 it increase the file size to double that before.
Even saving it with the same setting than before.
For example, most of my Business Card file that I sent to print, use to be 1.5 or so megabytes
Now if I open the same file, --or a new file-- and save it, it will increase it to double that size
Any ideas?
Thanks

Hola and Thanks for your help
Ok, I've been using Photoshop since version 6 or so (around year 2000)
Just upgrade to CS5
Before, for example, I'll make a file in PS, merge the layers, open a new file whit the same dimensions, resolution etc,
and save this file as PDF to send to printers.
Tthe file(s) that I have or were create them in CS4, than saved as PDFs have a file sizes of 1 to 2 megabytes as average.
The NEW files (in the same sequence) that I create now, have an average of 3 Mbytes
Even do, I save them with the same --I believe-- setting in PDF
There's may be a new feature in PDF save dialogue box that I'm not getting?
or, it just more information that it is put into?
Thanks

Digital signature increases the file size

My digital signature increases the file size from 262kb to 15meg. How can I reduce the file size?

Actually, it sounds normal. Try turning off the preference "Include Signature’s Revocation Status When Signing" but be sure you understand the consequences... that space is being used for something that might be important.

How do I increase the file size of a photo?

I have an iMac with Mavericks installed and took a photo with my iPhone 5 that I would like to increase to a 2 MB JPEG file size. How do I do this?

Export with higher quality (file menu ==> export - see the use tip on exportign for details on options)
However this will not change anything about the photo except the amound of disk sopace it uses - the photo is stil exactly the same no matter how large you make the file by reducing compression

Preview.app increases PDF file size.

When making changes to a PDF (in my case, creating annotations), Preview.app will increase the file size of a PDF if that PDF was run through Acrobat Pro's "Reduce File Size" process. For example, I have a PDF that I created using a Book2Net book scanner. I then used Acrobat Pro 10 to OCR the file, then ran Reduce File size which shrank the file size from almost 1.6gb down to about 62mb. If I use Preview.app to make an annotation and then save the file, Preview.app will inflate the file back up to 1.6gb.
An earlier thread (https://discussions.apple.com/thread/1478588?start=0&tstart=0) also discusses a similar issue. I'm not sure if those folks were also working with PDFs that were reduced in size by Acrobat Pro or not.
Anyone else have this issue?
10.6.8 on a MacBook Pro.

That is not normal. same action with acrobat and skim do not do this. Changing file size from 170mb to 780mb (my case) should not be expected.
Preview re-formats the file (which takes a while the first "save"). It may even make scrolling and searching for text faster, but is not desirable all the time.
There is NO explanation from Apple in help or online. Keeping things simple is one thing, having unexpected and unexplained behavior is another.
Last preview update made it pretty much useless for annotations anyways.
Choosing "text" annotation used to allow for clicking anywhere on the pdf and start typing. Now, it automatically creates a text box at the center of page that has to be the dragged (and make sure not dragging other annotations with it). click T multiple times, multiple text boxes on top of each other.
I never thought I would look at Windows users with jealousy. What a bad job they are doing.

Preview increases pdf file size when saving

When I save a PDF journal article using Preview, it often increases the file size by 2x - 4x, regardless of whether I have added annotations. In the attached image, you can see I downloaded a journal article (2.3 MB), opened it in Preview, duplicated and saved it and the resulting copied file was 6.1 MB.
This is a problem because I it signifiantly increases the size of my synced reference library. It is worse with larger files (25 MB eBooks that increase to 80 MB).
Can anyone help me find a way to annotate a journal article and preserve the original file size? I have tried Adobe Reader (awful and buggy interface, but preserves the original size!), and several other PDF apps (e.g. Skim) seem to rely on Apple's PDF engine where the file results in a larger size as well. Using Quartz filters to reduce file size within Preview is not effective. I'm happy to purchase a program if it works well.

I have also experienced this issue. My PDF file of 300MB increased to over 900MB when I simply put one straight line annotation onto it. Effectively this made the PDF unusable since it is now very slow to open and it is too large to transfer onto my iPad. I've experienced this multiple times with a variety of PDF files, and so now simply avoid changing them in any way in Preview. I have written to Apple via apple.com/feedback and have talked to Apple store 'Geniuses' about this. Apparently it is a known issue, but there was no promise of a resolution. I love the way Preview opens quickly and displays files and also allows beautiful, smooth scrolling of PDFs. It's a pity that there's this enormous problem with annotating. If anyone knows of a solution, it would be great to hear. I've tried other PDF programmes such as Adobe for Mac, but wasn't too impressed.

How can I reduce the file size in Adobe Reader 9?

My wordpress isn't allowing me to upload files larger than 2MB. How do I resize my PDF in Adobe Reader 9 so that it is <2MB?
Thank you very much for the help!

In Acrobat, open a PDF file.
-Choose Document > Reduce File Size.
-Select Acrobat 8.0 And Later for file compatibility, and click OK.
When you choose the compatibility level, be aware that the newer the version of Acrobat that you choose, the smaller the file. If you choose compatibility with Acrobat 9, however, you should be sure that your intended audience does indeed have version 9 installed.
Name the modified file. Click Save to complete the process.
It is always a good idea to save a file using a different name so that you don't overwrite an unmodified file.
Acrobat automatically optimizes your PDF file, a process that may take a minute or two. Any anomalies are displayed in the Conversion Warnings window. If necessary, click OK to close the window.
Minimize the Acrobat window. View the size of the reduced file. The file size is smaller.
You can repeat steps stated above using different compatibility settings to see how they affect file size. note that some settings might actually increase the file size.
PDF Optimizer offers more opportunities to control quality trade-offs.
Choose File > Close to close your file.

Optimize increases in file size by 5 times why?

Hi All,
This maybe a simple question but please hear me out. I take footage on my Go Pro HD 2 in 1080p. I have the files on a network storage device total filles size = 79GB. When I import to FCPX I run my events from a 1TB thunderbolt connect drive into my imac 27 inch for editing. If I optimize the modia on import to convert from MP4 (which edits fine in native in FCPX btw) to Apple ProRes 422 then the file size increases from 79GB to 379 GB which just seems ridiculous? I did have colour analyze also checked, but can someone let me know if this is normal? I wouldn't expect the ProRes to be 5 times the size of the original?
Thanks

Most modern consumer cameras shoot AVCHD or other very compressed footage.
This is fine for playback but the high compression puts a great strain on the processor during editing.
Turning it to ProRes 422 reduces the compression, so making it easier to edit but of course it greatly increases the file size.
When you have finished editing you can export the finished movie as AVCHD and once again it will be back to its original small size ....... or even smaller.
You can of course try editing your native footage without optimising but you may get lots of dropped frames and stuttering playback etc. making the editing process tedious.
Try it and see ........ you may be lucky if your computer is powerful enough.
You don't need colour analysis.

Increase Project File Size limit?

When I'm recording a longer song with real instruments, occasionally I will be told I can't record because I'm close to the 2gb file size limit. How do you increase the file size limit, or just get rid of it all together?
Thanks

I didn't know there was a size limit. I have Projects that are over 2 GB.

Preview.app increases PDF file size after deleting pages

Hello, I'm experiencing odd behavior with Preview.app and PDFs.
If I open a PDF with Preview, delete a page, then save the file, the file size increases anywhere form 2x to 20x. This happens both with PDFs that only contain text and PDFs that contain text and graphics. It is very frustrating because I start with a file that is 150KB, remove some pages and end up with a 10MB monster that I can't email to people.
Any help is appreciated. I can post a link to a test PDF for people to try to replicate with if it would be useful.

I generated the file with pdftex. I'm guessing that there must be different ways to encode a PDF and when Preview gets something with an encoding other than that provided by PDFKit, it rewrites the file how it likes. In my case this is increasing the file sizes. I tried finding docs about PDFKit on the Apple developer site, but couldn't find any details about ways of encoding a PDF.

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.

Email-to facilitate emailing a photo by gmail or AOL, I reduce the file size. Is it better to reduce the image size or increase the jpg compression?

To facilitate emailing a photo by gmail or AOL and avoid overwhelming the recipient's screen, I reduce the file size. Is it better to reduce the image size or increase the jpg compression? I have been making a duplicate image of 35 MB and reducing the image size to 8"x12" at 72 resolution giving a file size of 1.4 MB. Then I SAVE AS a jpg of medium compression giving a file size of about 111 KB. Overkill?

Go to File>save for web.
I usually make the long side 800 px
At the bottom of the dialog, check "constrain proportions."
At the top, select JPEG in the dropdown for the file format.
All the work is done for you! 72px/in is ok for web work. 240-300px/in is the recommended range for printing.
