Awesome, thank you!! Flags that may be of interest: --strip safe (or more aggressive --keep acTL,fcTL,fdAT) --alpha --scale16 (lossy!) --zopfli (probably only for highest level)

That issue was opened before v9 was released - it does support recompressing APNGs now, just not reductions yet. Worth another look at least.

Oxipng 9 is out now with APNG support. It also has way better optimisation now than earlier versions, so I think you'll find benefit regardless of APNG :)

Thanks, the readme only mentions 7za/7zr though, not 7zz.

Do you have any plans to add fast-lzma2 as an optional method for 7z/xz? It's an alternative implementation of lzma2 and is fully bitstream compatible but can provide a significant boost to compression speed for some workloads. You can see it in action in this 7-zip fork - I just thought it would be great if it was incorporated into the main codebase.

Thank you, that works! Sorry, should have checked the docs first (I just assumed it wasn't working because p7zip did it automatically). Quick question: What's the difference between 7za (Alone) and 7zz (Alone2)?
