Convert MPEG to APNG Online

Convert MPEG to APNG Online

Turn an MPEG video clip into an animated PNG that loops in the browser with full 24-bit color and per-pixel alpha transparency — something an animated GIF cannot do. APNG keeps every frame lossless, so gradients and soft edges stay clean instead of dithering into the 256-color banding GIF is stuck with. Upload a short .mpeg or .mpg clip, set a frame rate, and download a single self-contained .apng file.

How to Convert MPEG to APNG

1. Upload Your MPEG File: Drag and drop your .mpeg or .mpg clip onto the page, or click "Add Files" to browse. The file uploads over an encrypted connection to our servers.
2. Set the Framerate: Open the "FRAMERATE" dropdown and pick a rate — 10 FPS is the default and keeps the file small; raise it toward 24-30 FPS for smoother motion at the cost of size.
3. Tune Image Quality, Resolution and Colors (Optional): Use the "Image quality (%)" slider, the "Image resolution" controls to cap or resize the output, and "Colors" to keep the original palette or apply color reduction with dithering for a smaller file.
4. Convert and Download: Click "Convert" and download your .apng. No sign-up, no watermark — files are deleted automatically after a few hours.

APNG vs GIF vs WebP for Short Animations

APNG was folded into the PNG Specification, Third Edition, which became a W3C Recommendation in June 2025, and it is built on the PNG container — so a viewer that doesn't understand the animation chunks simply renders the first frame as a normal PNG. If you specifically need the broadest playback or smaller files, compare with MPEG to GIF and the GIF to APNG path.

Frequently Asked Questions

Why is my APNG file larger than the original MPEG?

MPEG-1 and MPEG-2 use lossy interframe (motion-compensated) compression, while APNG stores each frame as a lossless PNG. For anything longer than a few seconds the lossless frames add up fast. Keep clips short, lower the framerate, cap the resolution, or use color reduction to hold the size down. For longer playback, MP4 or WebP will almost always be smaller.

Will an APNG keep transparency that the MPEG didn't have?

No. MPEG video has no alpha channel, so the source is fully opaque and the resulting APNG will be opaque too. APNG supports 8-bit alpha transparency, but the converter can only preserve transparency that already exists in the input — it cannot invent a transparent background from solid video.

What framerate should I choose for MPEG to APNG?

10 FPS (the default) is a good balance for UI loops, reaction clips, and demos — it keeps the file manageable. For smoother motion, raise it toward 24-30 FPS, but expect the file to grow roughly in proportion to the frame count. There's no benefit to setting a framerate higher than the source clip's own rate.

Will an APNG play in every browser?

Native APNG playback covers roughly 95% of users — Chrome 59+, Firefox 3+, Safari 8+, and Edge 79+ all animate it. In a viewer without APNG support, the file still displays the first frame as an ordinary static PNG, so it never breaks completely. Legacy Internet Explorer and old Edge show only that first frame.

How large a file can I upload, and is it private?

You can upload short MPEG clips for conversion; the practical limit is upload size and time rather than your device. Files travel over an encrypted (TLS) connection, are processed on our servers, and are deleted automatically after a few hours. In our testing, a 5-second 480p MPEG clip at 10 FPS produced an APNG of roughly 2-4 MB depending on motion and palette settings.
