Convert OGV to APNG Online

Convert OGV to APNG Online

Turn an OGV clip — the open-source Ogg container that usually wraps Theora video — into an animated PNG that loops in the browser with full 24-bit color and 8-bit alpha transparency, no 256-color GIF banding. Drop in your .ogv, set the frame rate and output size, and download a self-contained .apng that falls back to a clean static first frame anywhere the format isn't recognized. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.

How to Convert OGV to APNG

1. Upload Your OGV File: Drag and drop your .ogv onto the page or click "Upload" to pick it from your device. A short clip converts fastest, since every frame is stored losslessly.
2. Set Framerate: Open the options and pick a value from the Framerate dropdown — 10 FPS (the recommended default) keeps the file small, while 20-30 FPS gives smoother motion at the cost of size. Frame rate is the single biggest lever on APNG output size.
3. Set Image Resolution and Colors: Use Image resolution (a percentage, a preset, or an explicit width/height) to shrink large frames, and leave Colors on "Original" for true color or switch to "By Color Reduction + Dither" for a smaller file. Image quality (%) controls the Zopfli-backed compression effort.
4. Convert and Download: Click "Convert" and save your .apng. No sign-up, no watermark.

APNG vs GIF vs Animated WebP

Frequently Asked Questions

Why is my APNG larger than the original OGV or an equivalent GIF?

APNG is lossless, so it stores every pixel of every frame exactly — there is no quality-discarding step like the Theora codec inside an OGV uses. In our testing, a short clip exported as APNG runs several times larger than an equivalent 256-color GIF, which is the expected trade for true color and clean alpha. To shrink the result, lower the Framerate (10 FPS is usually plenty for a UI loop), reduce the resolution, or trim the clip to the few seconds you actually need. Switching Colors to "By Color Reduction + Dither" also cuts size by reducing palette depth.

Will the OGV's audio be included in the APNG?

No. APNG is an image format and carries no audio track, so the Vorbis audio an OGV typically contains is dropped. The conversion uses only the video frames. If you need sound, convert to a video format such as OGV to MP4 instead of an animated image.

What happens in a browser that doesn't support APNG?

An APNG begins with a valid standard PNG chunk, so any browser or image viewer that can't animate it simply displays the first frame as a static PNG — there is no broken-image icon. Firefox, Chrome 59+, Safari 8+, and Edge 79+ animate it, covering roughly 94-96% of browsers worldwide. APNG was folded into the official PNG 3.0 specification in 2025, so support is no longer a vendor extension.

Should I convert my OGV to APNG, GIF, or WebP?

Choose APNG when you need crisp gradients, soft shadows or glows, smooth alpha transparency, or photographic frames without GIF's 256-color banding — for example a logo loop or a UI micro-animation. Choose OGV to GIF when universal compatibility matters more than fidelity, since GIF plays everywhere including old email clients. Choose OGV to WebP when the smallest possible web payload matters and you can accept a small lossy step.

How long is my OGV file kept on your servers?

Your uploaded OGV and the generated APNG are processed server-side and deleted automatically a few hours after upload. The transfer uses an encrypted connection, nothing is shared or made public, and you don't need an account. For big OGV files the real practical limit is upload time, not processing — trimming or downscaling first speeds things up. If your finished APNG is still too heavy to share, run it through Compress APNG to squeeze it further.
