I just bought a Macbook Air with OS 10.7.3 and the Preview menu has really changed from my old Macbook.   In Preview  I can no longer "save as" and change the size of a jpeg on the sliding scale as I did on my old Macbook.  How can I crop, resize & save as.... in the new Preview?   It seems to save automatically and I can't manually change the size to what I want and "save as".

I usually resize jpegs in a Batch for uploading to the web but sometimes individual jpegs still need  more cropping and resizing  to get them down to the size I want.....so I would  use the sliding scale in Preview.,,,,,,,,,,,     Thanks for any input.  Much appreciated.

    You're seeing the result of Lion's new Auto Save feature.  This was introduced in OS X Version 10.7 (Lion).

     

    Here's a detailed writeup:

    http://support.apple.com/kb/HT4753

     

    Bottom line:  You can do everything you could before, only somewhat differently.

    Change your workflow. You need to Duplicate first (it is in the File menu or you can click on the file's name in the title bar to see a menu there). Now you can make your edits and change.

     

    If you upgrade to 10.8 (as of 10.8.2) the old Save As functionality seems to be restored.

    It isn't a bug - it is a feature and one that I actually like since I can't count the number of times I've edited a file and then saved it instead of doing Save As. Duplication doesn't have a default keyboard shortcut but it is possible to add one using the Keyboard tab of System Preferences - this makes is a bit less onerous to use. In fact, my wife used a Macro program (Keyboard Maestro) to give Duplicate and Save as a shortcut. She opens a file, duplicates and Saves with a new name then does her edits and Saves when done.

     

    It has been so long since I used Snow Leopard that I don't remember how Preview worked in it. I do know that the 10.8.2 Preview shows the new file size after you've edited its dimensions.

    I would still like to know if 10.8.2  shows the kb size under the sliding scale in the Save As function in Preview so that you can see how large or small you are making it when you slide the quality slide from Best to Least?

     

    I know it's an old thread but is there an answer to this?

     

    When I'm saving a jpeg out of Preview, I used to be able to slide the "Quality" slider, and Preview would estimate the file size (in KB) of the file I was about to save.

     

    Is this possible any more under OS 10.8.2? I can't figure out how to do it and I need it.

     

    Thanks for any help.

    Try Tools > Adjust Size from Preview's menu.

    Thanks for your reply.

     

    This isn't quite what I mean. I need to adjust the quality of the image during the "save-as" step, with an estimate of the file size as I slide the slider.

     

    I need to turn on the "file-size" estimator -- if that makes sense. This feature is missing from the new version of Preview, at least in its default settings-set.

     

    I did this little side-by-side illustration to show what I mean, using the OLD version of Preview:

    Here's another thread about it where I think I've articulated the problem more clearly:

     

    https://discussions.apple.com/message/21324941?ac_cid=op123456#21324941

     

    If you can help me turn this feature back on I would be VERY GRATEFUL.

    You can do File > Export from Preview.  It will give you the quality slider as you show above, although not the file size.  You could get that after the fact by doing a Get Info on the new file from Finder.

    Thanks very much. Yes, command-i is helpful when you just need to know the size of the file.

     

    Here's what I use it for: I need to make all images under 250KB to post to a particular website. I do this all the time, but all the images start off in different quality, resolution and size because they're all from different sources. I don't want to change proportions, image size, or resolution -- just the file size (quality slider).

     

    So I used to click through them all, one by one, in Preview, and "save-as." I slide the quality slider down for each successive image until the file size is just under 250KB, then I save it.

     

    Without this feature, I have to do a trial-and-error for each image, then "command-i" each one. Some end up over 250KB, some too far under. So I try again on perhaps 90% of them, trying to remember which were too big and which were too small, and over and over again, getting just a few right with each pass, until all images are about the correct size.

     

    Something that used to take 5 minutes (for, say, 50 images) now takes -- no joke -- two hours.

     

    It doesn't seem possible that Apple really eliminated this feature -- and for what reason?

     

    Anyway, thanks for your reply. Much appreciated.

     

    If there is a good workaround in Preview I would love to know it, and I would be VERY GRATEFUL.

     

    My productivity at work just dropped about 95%.

    Streptile you are right on.  It was valuable and important, and it is gone.    The Apple software people, at a minimum, should restore the estimated file size (kb) so one knows where to get the slider before saving.   This enhancement is a "no brainer".  There are other Preview issues too which need attention.

    I am having trouble with this issue too.  I have a jpeg image that I want to make smaller.  I made a duplicate in Preview then did Tools-Adjust size.  I chose the size and then hit save but the system won't let me save the smaller version.  Any thoughts?

    Can I take it from this thread and others like it that this is a dead issue?  There is no work around and no interest from Apple in repairing the broken feature?

    I suggest you start a new thread since between the start of the thread and today there have been big changes.
