I need to optimize 700 images in PNG in a batch process, but Photoshop only gives me the option to optimize the images and export them to JPG, when I want to mantain the images on PNG. Is there a way to do this on Photoshop or in another tool? You can see the screenshot following this link.

You can probably do this by creating an action and then batch processing:

Create the action

  • with an open file in photoshop
  • start recording
  • do File > Save As > and set file type to PNG
  • or use File > Save for Web if you need to resize or make other modifications
  • click Save
  • stop recording and save action as "Save As PNG"

(there may also be some built in actions with Photoshop, I can't remember)

Then in Adobe Bridge

  • Select all the files you want
  • Tools > Photoshop > Batch
  • Select your "Save As PNG" action
  • Click OK to process

You want to use ImageMagick, its free and open source. Get it from http://www.imagemagick.org/script/index.php

Then use the "convert" function

You can try using "save for Web & Devices"

I hope this helps.

Thanks for your help; I followed the links but I'm having the same issue, because Photoshop only allows me to export the images to JPG, and I don't see the option to export the images to PNG. –  Moises Portillo Polio Jan 4 '13 at 17:18
    
The option should be there in save for web and devices ... top right corner. Anyways you can also try the free software GIMP to save images as png. GIMP is free alternative to photoshop. graphicssoft.about.com/od/gimptutorials/tp/save-PNG.htm –  Gaurav Jain Jan 8 '13 at 13:34

I found 'Riot - Radical Image Optimization Tool' perfect for batch converting images whilst retaining metadata

What makes it perfect? And I'm a little concerned about the name — can it do less-than-radical conversions if need be? –  mattdm Mar 19 at 12:36
