No – you won’t. this process replaces the existing file so make sure you have a copy if you still want to keep the original!

Works perfectly – I reduced 137Mb of photos to just 8.8Mb in about 1 minute! Quality was still fine for use in docs.

This just got me into big trouble.
I tried to batch process 300 photos in preview and it proceeded to open every one of them, freezing my mac.
I had to force quit. Now, however, anytime I open Preview, it commences with the process of opening all 300 pics again.
I’ve no idea what to do.
When I had a PC, I had a little program that just resized and put them all in a folder rather than opening up every picture.

Thank you. I also noticed that you can undo (command+z) if you want to revert back to the original file.

You don’t have to overwrite the original image. If you choose ‘Export’ you can choose where to save the image. (Lion)

Hahaha!

This is a good solution for a few dozen images but you can’t open a few hundred images and then perform the batch.

Searching for batch, I was thinking hundreds of images, this process is geared more towards a dozen or so.

If knowing this gets you closer to dropping Photoshop, you don’t know Photoshop.
