  3. Preview the result and download your .apng file.

Frequently asked questions

What is the difference between MNG and APNG?

Both are animated PNG-based formats. MNG is a legacy format not supported by browsers. APNG works in all modern browsers and falls back to the first frame in older software.

Does this converter preserve frame timing?

Yes. FFmpeg decodes each MNG frame and muxes them into APNG with the original per-frame delays.

Is my MNG file uploaded to a server?

No. Conversion runs in your browser via WebAssembly. Your file never leaves your device.

What is the maximum MNG file size?

Up to 200 MB. Large animations use significant browser memory because processing is entirely local.
