Changing photo file size

I am wondering how I change the file size of some photos that I need to send. I need the photos to be 40k and a maximum resolution of 400x400. I don't know how to resize them. I am sorry I can be a little slow when it comes to technology.
Thanks,
Vicki

Welcome to the Apple Discussions.
Select the file in the iPhoto Window and go File -> Export. The resulting dialogue will give you the option to resize the pic, then click export and choose a location where you want the smaller file to be placed.

How do I make a photo file size smaller? The photo is .jpg.

I need to make a photo file size smaller for some other uses.
imac Mac OS X (10.4.8) iphoto 5.0.4

Haha yes i forgot that you may not be using Apples Mail. Lets try the export then file>export, then under the heading "format" click JPG. Then click "scale images no larger then:" in the width field type "800" then the height field should change by itself. Thats what i do for emailing, it's usually the best trade between quality & size, that should be small enough to email. Best wishes JAG
P.S. when you first click "scale images no larger then" what's already in the width height fields? thats your actual photo resolution.

you need a DVD-authoring app, as iDVD, Burn, Toast ........... drag any iMovie export into it, 'burn'.

Photo File Size and Photoshop processing

On previous discussion, Steve Grisetti noted that problems with burning are sometimes associated with photo file size. The post stated that Photoshop Elements has a batch processing selection that can resize photos all at once. I when to Photoshop, selected process multiple file, selected source, save in same as source, and resize images 1000. When I viewed my photos after, about 50 of my photos were now duplicates of other photos For example, I put all my pictures in timeline order prior to doing my video. If I found a NEW photo after I had already scanned and named the photos, I would place the NEW photo in the picture folder by adjusting accordingly: 1.jpg, 2.jpg 3.1.jpg 3.jpg The 3.1.jpg would be the NEW photo. Photoshop replaced 3.1jpg with the picture in 3jpg. Does anyone know how to restore my photos back to the original "3.1jpg"? The backup is not accessible at this time.

If I understand you correctly you have been using the renaming feature and the parameters you used caused file1 to be renamed to a pre-existing filename (file2). If this is so then you probably have lost the original file2. An undelete utility may help (try Piriform Recuva).
For the future when using batch conversion it is good practice to select a new folder for the outputted files.
It is also good practice to burn all image originals to a CD or DVD immediately after importing from your camera. This way you can always recover originals.
Here are a couple of screenshots, the first from Elements Organizer and the second from Photoshop Elements. Which one did you use and what parameters did you enter?

Change the file size of a photo?

I am trying to send a photo for a contest, and they want the minimum file size to be 4 MB. My photos go into iphoto as 5.2 mb files, but when i crop them to 4x6 size the file size changes to 2.2 mb. i am taking pics at the highest jpeg quality in the camera (an Olympus e500.) Is there a way to increase that file size again, or should I be doing something different. I don't have the original photo--it is on a cd. Should I be saving both the original and the edited photos on cd's? thanks

Hi again!
It all depends on how many megapixels your camera has to work with. If you have a 5 megapixels camera or higher you should be ok with cropping down. I would probably do as much cropping as I could in Preview instead of iPhoto. But I just don't think you can crop to set dimensions in Previews
I would seriously think about downloading something like Graphic Converter: http://www.lemkesoft.com/ - it's a shareware and free to download and try. It may take you awhile to figure everything out, but it's a very very good image editing software. You can do exactly what you needed to do with your project using GC and a tons more... hope you do well with your photo projects!

Photo files size when importing from camera, uploading to facebook

When I import photos from my camera to iPhoto, then upload them to facebook, they are not the original size. This is my first mac and first time to use iPhoto so maybe that's normal. Is there a setting I need to change? How do I know if the files I have imported are being saved on my computer with their original specs? I am hesitant to clear the pics from my camera, fearing I might lose their original quality!

Welcome to the Apple Discussions.
As for facebook, when using my old pc the photos remained the original size after uploading. It wasn't until I used iPhoto that they began to upload in a smaller version.
Are you referring to file size as in KB or MB or image size as in pixel dimension. As Terence pointed out I doubt if Facebook will accept a full image files at the original size. Most are in the MB range and Facebook would run out of storage space in no time.
It might very well be that iPhoto will resize the pixel dimension of the photos to a "standard" size for uploading and Facebook then downsizes the actual file size. That means compressing the file to make a smaller file but not a smaller image.

Can I Change Photo/File Date In Photoshop Elements 2?

Whenever I change the batteries in my digital camera I have to reset the time and date.
Often I don't have time (or just forget) with the result that all the pictures have incorrect times and dates on them.
This is NOT destroying my life but it is irritating and inconvenient.
Is there a way of altering the "Date Created" without altering the photo by copying it etc. (which alters its file size)?
For that matter is it possible to alter the "Date Created" on any computer file?
I'm sure a hacker could delve deep into the heart of the Mac and do it but I am looking for something quick and simple.
Ian.

You can use PhotoInfo to change the dates on a single or batch of photos. You can even do it within iPhoto by selecting PhotoInfo as the editor to use when you double click on a photo. But iPhoto won't recognize the changes unless it's exported and reimported. You can use PhotoInfo to batch check/change your photos before importing into iPhoto.
What I've done is to export the full sized images to a folder on the desktop, named the folder the same as the roll they were in, run Photoinfo on the batch and then drag the folder into the open iPhoto. Then delete the original roll. Works fine.

Why do my photo file size increases upon export?!?!

This is driving me nuts. I have Aperture 1.5.2 referencing an iPhoto library. When I look at the metadata toolset I can see each photo's file size. I have all my photos already resized to fit in an 800x800px box. When I export through Aperture using "export version jpeg original" I get an increased file size. When I export using the master version I don't. I went through and added iptc caption data that only seems to export with the version not the master. I can't believe a line of txt adds so noticeably to the file size. If I need to export my photos with the iptc caption data and want to retain my original file sizes how should I go about it?
Thanks,
Michael

chuck,
it all depends on 2 factors. a - your original file (pixel dimensions, format, compression level, color and bit depth) and the exported file (pixel dimensions, format, compression level, color and bit depth).
just as an example - if you take a quite strongly compressed jpg (lets say at 5) and export it to be a less compressed jpg (10 to 12), the file size in kb will be larger, while maintaining the same amount of pixels. what has changed is the way the information are stored within the jpg +(to say it very simplified and without going into details about compression and possible loss of data etc)+.
if you'd take a high-res 16-bit tif and export it (again at exact same pixel dimensions) as jpg, you'd get a much smaller file, still the same pixels (at least the amount of pixels, however perhaps "lower quality" pixels, depending on compression level, original image, noise, tonality etc etc).
long (technical) story short: there is no real "one answer fits all" because it heavily depends on your original image. as a rule of thumb however, print files should be in 300 dpi and images for the web in 72.
in terms of color and bit depth it now depends who you're sending the files to. if you send them to your client, use 8 bit sRGB. if you send it to a graphic designer, i'd send him 16-bit tif files in adobe rgb. all of this makes no sense if your original image was a heavily compressed 8 bit sRGB jpg of course.

Edited Photo File Size Too Large

Hello
I don't really know the best forum to ask this question.
In simple terms, I have tried similar edits on the same photo (not much more than levels or curves, saturation and sharpening).
It is a jpg image.
The original file size is 3.4MB.
In the different photo editors, the file size changes after enhancement are as follows -
PhotoStudio 6 - 1.9 MB
Aperture 3 - 2.9 MB
Pixelmator 2.1.2 - 7 MB
Adobe Photoshop Elements 11 - 7.3 MB
I would like to know why the Pixelmator and Photoshop files are so much larger than the original.
I am slightly puzzled as to why the PhotoStudio and Aperture files are smaller than the original.
What I would like is an image which is close in size to the original, not something twice the size.
Could anybody help, please?

You can do somthing like this to get a preview image of those files:

Different photo file sizes when copied back from external HD

I backed up some photos to an external HD (80GB, same size as in my iMac at the time), with Mac OS Standard format, under Tiger. The internal HD crashed, taking much unbacked-up data with it to the digital beyond.
Now with my new Leopard iMac (and wisdom acquired by experience), I have noticed a different file size on the different drives after copying the photos back.
Other posts have pointed out differences in memory allocation / block size as the culprits, however, can that make the large difference seen in my case?
Example 1 is a Tiff file of 8.2 MB on the external HD, which shrinks to 6,8 MB when copied to the 500 GB iMac drive (taken from the Get Info window)
Example 2 is a JPEG which shrinks from 1.2 MB to 552 KB when copied over.
Examples 1 & 2 also shrank to 6.8 MB and 576 KB respectively when copied from the 80GB external drive to another, 320GB external FAT32 drive.
So my question is: Am I somehow losing something with the shrinking files? Does memory allocation/block size difference make that big a difference?
Thanks for your help.

I think I ought to mention that I also have a new laptop and have experienced file sharing permission issues with some applications. Might this be part of the problem? (Although everything seems to be properly owned!)

How do I reduce photo file size in Pages?

I am colaborating on a report that contains photos, which I want to exchange with my colleague via email. It's too big as is, but if I choose the Reduce File Size option, Pages over reduces and the photos become blurry and pixelated. If there a way to find a happy medium within Pages, and not be exporting to a pdf? Thanks in advance for any help.

Question asked and answered several times.
Adjust the picture files to fit your needs before inserting them in a Pages document.
My own scheme is :
build a draft document in which I insert the original pictures (tiff or png)
When the document's layout is OK, grab the dimensions of resized pictures.
Use a tool dedicated to pictures edition (they are numerous even if you want a free one).
to crop the pictures.
Re sample the cropped pictures with a rez between 80 dpi and 300 dpi according to your needs.
Then and only then, save as Jpeg to reduce the files sizes.
Remove the pictures embedded in you doc and insert the edited ones.
It may be useful to re-start from scratch and copy paste the text components if you applied masks to crop the pictures during the first step.

Photo file size

I'm being told that the total file size for photos on our business website should be 40KB or less per page. I can't seem to get the pictures that small. I usually end up in the 70-80 KB range. I know how to export and select specific pixel sizes but how can you compress/reduce them to a specific KB size?

Another useful 3rd part application for batch resizing is called Resize!. You'll have to export the files to a folder on the desktop and then run Resize! on it. It allows you to set the pixel dimensions and image quality, both of which will reduce the file size.
However, I don't think you can get very many photos on a site and keep the total size to 40 KB. They would have to be very small in pixel dimensions and at a very low quality. The smallest I could get a 640 x 480 image was 20. That was at the lowest quality setting which was very obvious. Are you sure that was 40KB for the site or per photo? Per photo sounds more reasonable.
If you go to VersionTracker.com and do a search for "resize" you'll find a number of other possible candidates for resizing photos.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.

Photo file sizes for emailing

Greetings
I normally take photos at the highest resolution, making for some large file sizes.
I was wondering how or if its possible to email pictures taken from the camera as a smaller file size, without having to convert/crop/manipulate the picture so that we don't fill up anyone's inbox with 50megs of photos. Especially since we have some friends still on dial up.
This is basically for the wife, who just wants to take pics off the camera and send them to friends as easily as possible without sending huge emails to people.
Hope I explained that properly.
Thanks for any input.

Hi new2mac222: It is quite easy to do actually from within iPhoto. Select the photo(s), then select the eMail Icon. The first dialog box that pops up will allow you to select the size of the files to be sent. There is also a selection box in the bottom right corner of the new eMail dialog box.
Note: These instructions based on iPhoto '08, so yours may be slightly different.
Hope this helps

Photo file sizes

I just started making an iWeb site recently, but I've stopped way before it's finished. I really love the software, but I'm worried about the file sizes (photos). The welcome page is really slow to load, and the photo on there is apparently a png. I've checked the boards here, but I don't know how I can speed this up. Without Photoshop, can I resize it? Doesn't iWeb resize for us?
http://web.mac.com/jamieland
Also, if you look in the Photos section, under Discovery Museum, the second pic on the page of my little boy leaning on the huge tree trunk (for eg.) was 2.0MB in iPhoto, and is 192KB on the site. Over my parents' prehistoric dial-up, it's painful. These photos are jpeg (not png). Does 192K seem big, or is this pretty standard as a scale-down from 2.0MB?
The site is also very slow over broadband, I'm told. What do you think? Is this slow? I'd appreciate any opinions or ideas...
Thanks!

Hi,
I used "Modern" as a template.
Photosize looks good if I don't use Reflection or other special on the normal pages in iWeb 1.0.1.
But if I look at my Blog entries, it's terrible.
Every Blog entrie has two times the same photo, one image.jpg (with about 80 to 100kb) and one image_1jpg with the original filesize from iphoto.
Why do I have these two files and why does iWeb upload the original file with a "_1" in the name?
I don't want the large file to be uploaded!
What's wrong?

Photo file sizes and iPhone

My digital camera files has extremely large file sizes - around 10mb. When I sync iphoto with the iphone I'm planning to get, will it resize the files and upload a smaller version to the iPhone? I hope so or my iphone will fill up pretty fast.

Photos transferred from your computer to the iPhone will be "optimized" for viewing on the iPhone but how much smaller in size these photos will be, I'm not sure.
My iPod with video includes a setting to transfer full resolution photos but the iPhone does not include the same option.
