Convert MP4 to APNG Online

Turn an MP4 clip into an animated PNG that keeps full 24-bit color and a real alpha channel — the two things a GIF throws away. APNG is the right output when you need a short, crisp loop with smooth transparent edges (soft shadows, anti-aliased logos, glows) and GIF's 256-color banding looks cheap. Pick your output framerate, cap the resolution, and download a lossless-frame animation with no sign-up and no watermark.

How to Convert MP4 to APNG

1. Upload Your MP4 File: Drag and drop your .mp4 or .m4v onto the page, or click Upload to browse. The file is sent over an encrypted connection.
2. Set FRAMERATE: Choose the output frame rate from the FRAMERATE dropdown — 10 FPS is the default and keeps the file small; raise it toward 20-30 FPS for smoother motion at the cost of size.
3. Adjust Image Quality, Image Resolution, and Colors (Optional): Use Image quality (%) and the Image resolution presets (or Width x Height) to control sharpness and pixel size; leave Colors on ORIGINAL for full color, or switch to By Color Reduction + Dither to shrink the file.
4. Convert and Download: Click Convert. Frames are extracted, assembled into an APNG, and optimized — then your file is ready to download. No sign-up, no watermark.

APNG vs GIF vs Animated WebP

For maximum reach or smaller files you may prefer MP4 to GIF; for the smallest web-delivered loop, try MP4 to WebP.

Frequently Asked Questions

Does APNG keep the transparency that GIF loses?

Yes. APNG carries a full 8-bit alpha channel, so semi-transparent pixels, anti-aliased edges, soft shadows, and glows stay smooth. GIF only has 1-bit transparency — each pixel is either fully visible or fully transparent — which produces the jagged "halo" outline you see when a logo or sticker is placed over a colored background. If transparency quality is why you're avoiding GIF, APNG is the format you want.

Why is my APNG larger than the GIF would be?

APNG stores lossless frames with full 24-bit color and a real alpha channel, so it does not throw away color data the way GIF's 256-color palette does. That fidelity costs bytes. In our testing, a 5-second 480p clip exported as APNG at 10 FPS was noticeably larger than the same clip as a 256-color GIF. To shrink it, lower the FRAMERATE, cap the Image resolution, drop Image quality (%), or switch Colors to By Color Reduction + Dither — and if size matters more than transparency, convert to GIF or WebP instead.

What framerate should I pick for an APNG?

10 FPS (the default) is a good balance for short UI loops, stickers, and emotes — it stays smooth enough while keeping the file manageable. Bump it to 20-30 FPS only when the motion is fast or you need cinematic smoothness, since file size grows roughly with frame count. There is no benefit to exceeding the source video's own frame rate.

Will an APNG play in every browser?

APNG renders natively in Chrome 59+, Edge 79+, Firefox 3+, and Safari 8+ — about 94.7% of browsers worldwide per caniuse. Anything that does not understand the animation simply shows the first frame as a normal static PNG, so it degrades gracefully rather than breaking. That first-frame fallback is part of the APNG spec.

Is my uploaded MP4 kept private?

Your file is uploaded over a TLS-encrypted connection, converted on our servers, and automatically deleted after a few hours. There is no sign-up, no watermark, and your files are never shared or made public.
