Details
How this should help in practice
These sections explain the job in plain language and set expectations for what the tool should do well.
Why APNG optimization needs a dedicated path
Static PNG compression is not enough for animation. APNG files carry frame timing, looping behavior, and full-frame image data that need to be handled together.
That is why this tool should stay focused on APNG-specific tradeoffs such as frame duplication, frame-rate caps, and indexed color reduction.
What the presets should actually change
The presets should guide common tradeoffs rather than hide them. Lossless cleanup keeps color detail, smaller-file mode reduces colors and frame rate modestly, and aggressive mode pushes harder when size matters more than subtle fidelity.
FAQ
Common questions
Short answers for the questions people usually have before trying a utility like this.
Will this work on a normal static PNG?
No. Static PNG files should go to the PNG-8 Quantizer instead. This page is for animated PNG files only.
Can this preserve the APNG format?
Yes. The export stays APNG so the result remains an animated PNG rather than a GIF or video.
Does this upload the APNG to a server?
No. The animation decode, frame cleanup, and re-encode happen locally in the browser.
