Reducing APNG size while keeping the file in PNG format instead of switching the workflow to GIF or video
Capture APNG optimizer intent with a browser-first export that feels more specific than a generic image compressor
Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To reduce an APNG's size, upload the animated PNG, pick a smaller-file or aggressive preset, and export. The optimizer merges duplicate frames, caps the frame rate, and reduces colors to shrink the file while keeping it in PNG format rather than converting it to GIF or video.
APNG carries frame timing, looping behavior, and full-frame image data, so plain static PNG compression is not enough. This tool handles those animation-specific tradeoffs together to get real size savings.
The presets guide common tradeoffs instead of hiding 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.
All decoding, frame cleanup, and re-encoding happen locally in your browser, so the animated PNG is never sent to a server. That makes it safe for private or unreleased animations you need to keep on-device.
Short answers for the questions people usually have before trying a utility like this.
Yes. The APNG Optimizer is free with no signup and no watermark, and it runs in your browser with nothing to install.
Upload the animated PNG and pick a smaller-file or aggressive preset. The optimizer merges duplicate frames, caps the frame rate, and reduces colors to compress the APNG while keeping it in PNG format.
Yes. The export stays APNG, so the result remains an animated PNG rather than being converted to a GIF or a video file.
No. The animation decode, frame cleanup, and re-encode all happen locally in your browser, so the file never leaves your device.
No. This page is for animated PNG files only. For static PNG compression, use a PNG quantizer instead.
Every tool on Cleanor is free with no sign-up, no credits, and no limits. Files are processed privately in your browser. Looking for on-device phone cleanup and Premium features? That lives in the Cleanor app.
Re-encode one APNG, merge duplicate frames, cap the frame rate if needed, and reduce file size without sending the animation to a server.
