PREVIEW: Why doesn't Preview estimate file size when saving-as?

I understand that Preview's "save-as" feature has changed -- now you must duplicate the image first, then save it.


However, when I save a duplicate (which is similar to the old "save-as" feature), I need to have the "Quality" slider linked to a feature that estimates the file size of the image I am saving.


Thhis was a function built right into the old Preview.


How can I enable it in the new Preview?


In other words, how can get Preview to estimate the file size (in KB) of the image I am saving when I slide the "Quality" slider?


Thanks for any help.

Thank you for your reply! That's great.


BUT...


What I really need is for Preview to estimate the file size of the image I am saving.


It used to be right there, next to the "Quality" slider. When you moved the slider, it estimated the size of the image you were about to save.


How can I get that to show again?? This is killing me and I really appreciate your help.

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, 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?


Are there Apple representatives on this board? Or is this just a community of users helping one another?


Anyway, thanks to all who have replied so far. Much appreciated.

I never had cause to need this function, but thinking about I can see how crucial it could be in certain circumstances (yours) and I can't see a way around it!

Send your thoughts there, I will as well.

Eric, Network and Csound,


Thank you very much for trying to help me out, and for your replies.


I was really hoping this one would be an easy fix, like "turn it on in the ___ menu, duh" -- but I guess I'm really out of luck here.


I will send a suggestion to Apple, but browsing this thread:

...gives me little hope.


Best,Trevor
