Optimize APNG images in a browser-only batch. Every successful result remains APNG, and files are never uploaded.
Every successful output remains APNG.
Files stay in this browser tab and are never uploaded. Up to 50.0 MiB per file and 200 files.
The batch workspace is ready. Compression becomes available when the verified image optimization adapter loads.
The browser decodes, optimizes, and re-encodes each file as APNG. The tool never switches formats automatically.
APNG optimization retains full-color frames, alpha, timing, and looping while rebuilding the PNG-compatible animation with lossless compression.
