Convert WEBP to APNG Online

Convert WebP to APNG Online

Animated WebP is small, but plenty of editors, chat apps, and older viewers still refuse to open it. Converting to APNG (Animated PNG) trades a little file size for near-universal compatibility: APNG is lossless, carries full 8-bit alpha transparency, and the first frame degrades gracefully to a plain PNG anywhere the animation isn't supported. This tool keeps every frame and the original timing, then hands you a clean .png/.apng that opens almost everywhere.

How to Convert WebP to APNG

1. Upload Your WebP File: Drag and drop your animated or static .webp onto the page, or click "Upload" to add it from your computer, Google Drive, or Dropbox.
2. Set the Framerate: Leave it on "10 FPS (Recommended)" to match a typical sticker or loop, or raise it for smoother motion at the cost of a larger file.
3. Tune Image Quality, Colors, and Resolution: Adjust Image quality (%), apply Color Reduction with Dither to shrink the palette, or pick a smaller Image resolution preset if you want a lighter output.
4. Convert and Download: Click "Convert," then download your APNG. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours — no sign-up, no watermark.

Animated WebP vs APNG vs GIF

Frequently Asked Questions

Why convert WebP to APNG instead of keeping the smaller WebP?

Compatibility. Animated WebP only plays in Chrome, Firefox, Edge, and Safari 14.1 or newer, and many image editors, messaging apps, and social platforms still reject it outright. APNG works in every major browser back to Safari 8 and Firefox 3, and image tools that understand PNG generally handle it too. You give up some file size to get a file that opens almost anywhere.

Will I lose quality going from WebP to APNG?

If your source is a lossless WebP, no — APNG is also lossless, so the pixels come through exactly. If your WebP was saved with lossy compression, APNG can't recover detail that was already discarded, but it won't add new artifacts on top. The APNG will usually be larger than the WebP, because lossless DEFLATE compression can't match WebP's lossy encoding.

Does the conversion keep transparency and all the animation frames?

Yes. Both animated WebP and APNG support full 8-bit alpha, so soft, anti-aliased edges survive the conversion intact — unlike GIF, which only has on/off transparency and produces jagged outlines. Every frame and its timing are preserved, and you can adjust the playback framerate during conversion if you want.

How large can my APNG file get, and is there an upload limit?

In our testing, a 480p, 3-second animated WebP at default settings produced an APNG roughly 2 to 3 times larger than the original, since lossless PNG compression can't match WebP's lossy encoding. To keep the output smaller, lower the framerate, apply Color Reduction with Dither, or pick a smaller resolution preset. The practical constraint on your side is upload size and time, not your device — large files simply take longer to send over the connection.

Can I convert the APNG back to WebP or to a GIF later?

Yes. Use APNG to WebP to go back to the smaller animated WebP, or WebP to GIF if you need the maximum legacy reach of GIF instead. Keep in mind GIF caps out at 256 colors and only has on/off transparency, so detailed or soft-edged animations lose quality when flattened to GIF.
