I need to save a jpeg for ebay, It has to be 800 X 600 and 80kb max. Can someone tell me how?

Question

I am composing pics in photoshop to add a backgound and need to save it as a jpeg set to ebay standard of 800X600 at no more than 80kb in size. Can someone walk me through that process?

Answer 1

The 80kb refers to the file size.
Yes, you can use Process Multiple Files to do the resizing part (the pixel dimensions) but you won't know what the files size ends up being until after the resizing is done.
In Save For Web, underneath the Preview on the right, the file size for the resized images is shown, so you can keep tweaking things until it is below 80k.
If you have a lot of files to resize, then Process Multiple Files may be best, and then just go fine tune just the ones that end up bigger than 80k.
If you only have a few to resize, then use Save For Web, as you'll only need one go at it to get it under 80k.
The basic flow in Save For Web would be:
Open image in Editor
File>Save For Web
In the New Size section, set your pixel dimensions (800x600) and click Apply
Up in the Preset section, pick your file format. Probably want to use JPEG
Look at the File Size (second line of text under the preview on the right)
Back in the Preset Section, select the Quality from the pulldown to have the highest quality that still gets you under the 80kb file size. You'll notice that as you select different quality settings, the File Size will change accordingly. Lower quality gets you smaller files.)
