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
To resize a batch of photos, open a terminal window to the folder containing your photos and use the command:
mogrify -resize 700x700 *.png
You can try using "save for Web & Devices"
Some helpful links:

- (video) Photoshop Top 40 #34 - Save for Web & Devices
I hope this helps.
- Create your action -In your action you MUST "SAVE AS .png"
- Go to "Automate > Batch -Choose your action, folder, desitination -YOU MUST THEN, Check the box "Override Action "Save As" Commands
Click "OK" and wallah! If you saved your action correctly with the "save for web / .png", you will have your image assest outputted properly as .png's
NOTE - You will find your outputted folder only on the Desktop, as Windows 8 Photoshop CC folder save location is "FUBAR"
Just shift click all of your layers. then right click export as. make sure the layers don't live in folders.
