Script is Great - PNG Size is Gigantic!!!

I have hacked the following script to batch convert supported file types found in the first level of an input folder to transparent sRGB PNG-24 files exported using Save for Web. Output files will be in a new folder in the input folder titled “sRGB PNG Batch Output”.

With my minimal scripting knowledge, it is amazing that I am able to get this result – so test, test, test to make sure that it does what you require! Tested in CS6 and CC2018 on the Mac OS.

P.S. On your original issue, save as PNG can include metadata, while Save for Web will strip metadata. There have been cases of excessive file bloat caused by excessive amounts of photoshop:DocumentAncestors metadata (which may or may not explain the large file sizes).

Thanks!

Now I can't find the scripts folder for the manual install. WHAT A PAIN!

AUUUGGGHGGHHGHHH

I tried to install Image Processor Pro with Adobe Extension Manager CC and it WON'T work.... So frustrated.

I get this message,

I am running Photoshop CC.

Any Ideas? 

Thanks.

Thanks everyone!  I didn't even know there was an image processor PRO.

I will give it a try!

This Script seems to save a plain png, have you tried a Save for Web PNG?

What are the psd file’s pixel dimensions and size (as indicated in the Image Size dialog)?

Try changing the png save options to save a smaller file. Looking at the script I do not think it will save you any Time and may actually take longer then just doing as png. In fact it should take longer for it first saves the current document duplicates it. In the dupe it merges visible layer and deletes other layers then save out a png and closes the dupe but does not use the no save option you will most likely have to reply to a dialog that ask if you want to save the modified dupe.  I do not think much of that script
