Convert APNG to WTV Online

Convert APNG to WTV Online

This converter turns an animated APNG into a WTV file — the Windows Recorded TV Show container Microsoft built for Windows Media Center. It plays each PNG frame as a short video clip inside an MPEG-2 stream, so your animation lands in a format that a Media Center library will recognize. Be candid with yourself first: WTV is a legacy, niche target (Windows Media Center was discontinued in 2015 and dropped from Windows 10), so unless you specifically need a Media Center-compatible file, converting APNG to MP4 gives you a far more playable result everywhere else.

How to Convert APNG to WTV

1. Upload Your APNG File: Drag and drop your .apng (or .png animation) onto the page, or click "Add Files" to pick it from your device.
2. Set the Quality Preset: Choose a Quality Preset — "Very High (Recommended)" keeps detail, while lower presets shrink the file. Because APNG is lossless and WTV re-encodes to MPEG-2, this is where you trade size against fidelity.
3. Adjust Video Resolution, Background Color, and Image Duration: APNG transparency is flattened onto a single Background Color (black by default), Image Duration sets how long each frame holds, and Video resolution lets you keep the original or pin a fixed size.
4. Convert and Download: Click Convert, then download your .wtv file. No sign-up, no watermark — files upload over an encrypted connection, run on our servers, and are deleted automatically after a few hours.

WTV vs MP4 for an APNG Animation

Frequently Asked Questions

Why would I convert an APNG to WTV instead of MP4?

Almost no one should. WTV is the recorded-TV format for Windows Media Center, which Microsoft discontinued in 2015 and removed from Windows 10. The only real reason to pick WTV is feeding an animation into a still-running Media Center library on Windows 7 or an older Media Center build. For everything else — phones, browsers, editors, social uploads — APNG to MP4 is the practical choice.

What happens to my APNG's transparency in a WTV file?

WTV stores MPEG-2 video, which has no alpha channel, so transparency cannot survive. Any transparent pixels in your APNG are flattened onto the single Background Color you choose (black by default). If your animation relies on a transparent background, set the Background Color to match the surface you'll place it on before converting.

How long will each APNG frame show in the WTV video?

Each frame is held for the Image Duration you set — the default is 5 seconds per frame. A long-running APNG with many frames will produce a long video at that pace, so for a fast looping animation you'll usually want a short duration (a fraction of a second per frame) to mimic the original timing.

Will the WTV file play outside Windows Media Center?

Rarely without help. WTV is a proprietary Microsoft container, so most general-purpose players and mobile apps don't open it. VLC can play many WTV files on the desktop, but there is no native phone or browser support. If you need broad playback, convert to MP4 instead.

Is APNG to WTV lossless?

No. APNG itself is lossless, but WTV wraps an MPEG-2 (or MPEG-4) video stream, which is lossy. Re-encoding discards some detail, and a higher Quality Preset only reduces — never eliminates — that loss. In our testing, a short 480p APNG at the "Very High" preset stayed visually close to the source, but fine gradients and sharp text soften slightly compared to the original PNG frames.

Are my uploaded files kept private?

Yes. Your APNG uploads over an encrypted connection, the conversion runs on our servers, and the output is deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public.
