Convert APNG to Video Online

How to Convert APNG to Video

1. Upload Your APNG File: Drag and drop your animated .apng onto the page or click "Upload". You can add several APNG files at once and choose later whether they become one video or one video each.
2. Pick an Output Format and Quality Preset: Choose the target from the Video File Extension dropdown — MP4 is the default and the safest pick — then set the Quality Preset (Constant or Constraint Quality) and Preset level (Very High is recommended).
3. Set the Background Color and Resolution: Standard video has no alpha channel, so APNG transparency is flattened onto the Background Color you choose (black by default). Use Video resolution to keep the original size or scale to a preset.
4. Convert and Download: Click "Convert" and download your video. Files are uploaded over an encrypted (TLS) connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.

Popular APNG Conversions

• APNG to MP4 — the universal choice; H.264 plays on virtually every phone, browser, and editor
• APNG to WebM — smaller files for the web; VP9 keeps quality high at low bitrates
• APNG to MOV — for dropping the clip into Final Cut Pro, iMovie, or other Apple-first editors
• APNG to GIF — when you need a single looping image that embeds anywhere without a video player

Why Convert an APNG File to Video?

APNG (Animated PNG) is a frame-based animation format that extends the static PNG. As of PNG Third Edition — a W3C Recommendation published June 24, 2025 — APNG is part of the official PNG standard, with its own image/apng media type. Its strength is fidelity: APNG stores full 24-bit color with an 8-bit alpha channel, frame by frame, with no lossy compression. That lossless, per-pixel transparency is exactly why a few seconds of animation can balloon to several megabytes.

Converting to a video format trades that fidelity for size and reach. An H.264 MP4 of the same animation is typically a small fraction of the APNG's size, and it plays natively in browsers, on phones, in social apps, and in video editors — places where an APNG either won't autoplay or isn't accepted as an upload at all. The one thing you give up is transparency: standard video formats have no alpha channel, so any transparent pixels in the APNG are composited onto a solid background color of your choosing.

Common reasons people make this conversion: putting an animation on a platform that only accepts video, shrinking a heavy APNG so it loads quickly, importing animation frames into a timeline editor, or producing a looping clip for a slideshow.

Frequently Asked Questions

What is the best format to convert APNG to?

For nearly everyone, MP4 with the H.264 codec. It is the most widely supported video format across browsers, phones, editors, and social platforms, and it produces small files at good quality. Choose WebM (VP9) if your priority is the smallest possible file for the web, or MOV if you are importing into an Apple editor like Final Cut Pro or iMovie.

Will I lose the transparency in my APNG?

Yes — standard video formats (MP4, WebM, MOV, AVI, and the rest) have no alpha channel, so transparent areas cannot be preserved. The converter composites your animation onto the solid Background Color you select (black by default). If you need a transparent result that still animates, keep it as APNG or convert to an animated WebP instead.

Why is my MP4 so much smaller than the original APNG?

APNG stores every frame losslessly with full color and alpha, which is inherently heavy. Video codecs like H.264 and VP9 use lossy inter-frame compression, encoding only what changes between frames. In our testing, a 3-second 480x480 APNG of around 6 MB converted to a roughly 300–500 KB MP4 at the Very High preset — over a 10x reduction — with no visible difference at normal playback speed.

Why does my logo have a dark fringe or halo in the converted video?

Because of how anti-aliased edges are flattened. An APNG's alpha channel is not just on-or-off: the pixels around a curved edge are partly transparent so the shape looks smooth against any background. When the animation is composited onto the solid Background Color for video, those semi-transparent pixels blend with that colour — so a white logo on the default black background picks up a grey rim, which reads as a halo once it sits on a light page. The fix is to set Background Color to the colour the video will actually be shown against, so the blend is invisible. If the destination background varies or you cannot predict it, keep the animation as an APNG or use an animated WebP, both of which preserve real transparency.

How is the frame rate or speed of the video decided?

For a true animated APNG, the converter reads the per-frame timing stored in the file, so the video plays at the same speed as the source animation. The Image Duration control only applies when you upload still images (non-GIF) to build a video from scratch — it sets how long each picture is shown — so you can usually leave it alone for an APNG.

Can I combine several APNG files into one video?

Yes. Use the Merge strategy option: "Merge images" stitches all uploaded files into a single continuous video, while "Video per image" produces a separate video for each file. Pick "Merge images" if you want one clip that plays your animations back to back.

My APNG won't loop in the video — how do I make it repeat?

Video formats have no built-in loop flag the way APNG does, so the clip plays once unless the player is set to loop. Enable looping in your video player or, for web embeds, add the loop attribute to the HTML <video> tag. For social platforms, short clips often auto-loop on their own.

Are my files kept private during conversion?

Yes. Your APNG is uploaded over an encrypted (TLS) connection, converted on our servers, and the upload is deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public. The main practical limit on a very large APNG is upload size and time, not your device.
