gglover - I know that if you look for the action tool bar in PhotoShop you can save yourself a "macro" which will duplicate any command sequence that you want to do. You can then go to file --> Automate --> Batch and select the action you created and apply it to all files in a folder. Sounds like this would work great for what you want to do.
Is there a simpler/faster way via the above software or a utility to make multiple but simple conversions like this?
Yes (The basic command list in Fireworks is inadequate).
I found the best way to make the most from fireworks batch process feature is to create a command yourself for the type of batch you want (eg: file ext, scale, DPI, filter, etc) and then to use your command from the list when prompted. Very similar process to what was suggested by Monksp with PS.
Take a look in the FW help section for creating commands if you have not tried it.
Wow - I very much appreciate the suggestions. My problem with Fireworks is that it seems to insist on saving a .png file for each .jpg I want to convert. But any macro-type thing would be better than none and I'll have to explore it more.
I just downloaded and installed Irfanview but haven't tried it yet. It seems to "know" a lot of formats, so depending on the automation capabilities, it may be great.
I'll look for Advanced Batch Converter as well, as the name itself sounds exactly like what I need.
Again, I appreciate all the timely and good advice!
