Is there a program that can do batch conversions of gif's to jpg's? I've got about 1000 gif's I need to convert and have no intention of opening each one and saving it as a jpg.
If you have Photoshop, it can do it by running a simple Action. Here is a link on how to create an Action in PS. Always do a test run first to make sure you set the action up correctly before doing what you need done. I use actions all the time in PS for batch processing. I am sure you will get others.
What this means is that if you convert a GIF into a JPEG, you will lose image quality because you'll be going from lossless to lossy, and your 256-colours images won't magically gain 16.7M colours either. And if you try to maintain the quality by using "100%" for the JPEG quality parameter you will only end up with a file that's even bigger than the GIF. You will probably hit the same file size as the GIF even with a much lower JPEG quality setting, too.
It would help if you could tell us why you need to convert your images.
