Convert VOB to APNG Online

VOB is the DVD-Video container found in a disc's VIDEO_TS folder — an MPEG-2 program stream that bundles video, audio, and subtitles together. This tool pulls a segment of that footage and rebuilds it as an APNG (Animated PNG): a lossless, 24-bit animation with smooth alpha transparency, perfect for a clean clip from a home-movie or archived DVD where GIF's 256-color banding would show. You set the frame rate, resolution, and color budget; we handle the MPEG-2 decode and the PNG re-encode.

How to Convert VOB to APNG

1. Upload Your VOB File: Drag and drop your .vob file onto the page or click "Upload." Files travel over an encrypted connection and are deleted automatically after a few hours.
2. Set the Framerate: Open the options and pick a value under "Framerate" — the default is "10 FPS (Recommended)," which keeps the animation smooth while holding the file size down. Higher FPS looks smoother but grows the APNG fast.
3. Tune Image Quality, Colors, and Resolution: Adjust "Image quality (%)" for the lossless re-encode, cap output size with "Preset Resolutions" (or "Width x Height"), and use "Colors" with dithering if you want a smaller palette. Leave "Colors" at ORIGINAL for full 24-bit fidelity.
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 a GIF of the same clip?

APNG is lossless and keeps full 24-bit color, so it never throws away pixel data the way GIF's 256-color palette and dithering do. That fidelity costs bytes. To shrink the output, lower the "Framerate," drop the "Preset Resolutions" to 480p or 360p, or reduce "Colors" with dithering — each trims size at a predictable quality cost. If small size matters more than lossless quality, an MP4 or animated WebP will be far smaller.

How long a clip can I turn into an APNG?

APNG is meant for short loops, not full DVD chapters. Because every frame is stored losslessly, a long VOB segment produces a very large file that browsers load slowly. In our testing, a 5-second 480p clip at 10 FPS produced a roughly 2-4 MB APNG depending on motion and detail — keep segments short (a few seconds) for a file that's practical to share or embed. If you need the entire title, convert VOB to MP4 instead.

Will the APNG keep transparency from my VOB?

No — VOB footage from a DVD is fully opaque MPEG-2 video, so there is no alpha channel to carry over. APNG supports 8-bit alpha transparency, but it can only preserve transparency that already exists in the source. Your output will be a solid, fully opaque animation.

What's the largest VOB file I can upload?

Uploads are capped at 200 MB. A single VOB on a DVD is often near 1 GB because DVD authoring splits a title into ~1 GB chunks, so you may need to trim or convert the relevant section rather than the whole file. The real constraint is upload time, not your device — files are processed on our servers, not in your browser.

Should I use APNG or GIF for a clip from an old DVD?

Choose APNG when the footage has gradients, fine detail, or text that GIF's 256-color limit would visibly band. Choose GIF when you need it to play literally everywhere — every browser, chat app, and legacy device renders GIF, while APNG falls back to a static first frame on the rare client that lacks support. For the wider-compatibility route, convert VOB to GIF.
