Add lossless png compression

Open MemQu opened this issue 8 months ago • 3 comments

Feature Description

I would like to see png compression programs like optipng and oxipng

They are used in reducing the size of png without any loss

Technical Details

It shouldn't be more difficult than running a subprocess with a command

Existing Implementations

Curtail uses oxping. OptiImage uses oxipng too.

The "Smallest Lossless" mode already uses Oxipng. You can leave just the "PNG" format enabled to recompress your PNG images.

"Max Compression" uses -o 4 instead of -o 2.

I was considering expanding it but I'm unsure if enough people woud use it.

Lol, came for the same. Add oxipng options in "PNG" mode Effort (-o 1,2,3,4,5,6,max), zopfli. Will be much more convenient, especially compared to the console version

and use that options for "JPEG Reconstuction" png fallback
