Convert APNG to WTV Online

APNG to WTV Converter

APNG is a web animation format; WTV is the Recorded TV container Windows Media Center wrote to disk. This converter bridges the two: every frame of your animated PNG is re-encoded as video and wrapped in a .wtv file, so a Media Center-era library or a tool that only ingests recorded-TV files will accept it. Two things change on the way — the output is silent, because an APNG has no audio track, and the transparency is composited onto a solid Background Color, because video pixel formats have no alpha channel. WTV is a genuinely niche target; if you simply want a playable clip, APNG to MP4 is the answer instead.

How to Convert APNG to WTV

1. Upload Your APNG File: Drag and drop the file onto the page or click "Add Files". Both .apng and animated .png are accepted, and each upload becomes its own .wtv.
2. Set the Quality Preset: Under File Compression, Quality Preset starts at Very High (Recommended) for a near-source look; step it down to shrink the file, or switch to Constant Quality to set the CRF value yourself.
3. Pick the Background Color and Video resolution: Background Color — White by default — replaces the transparency in your APNG, and also fills any letterbox bars. Video resolution stays on Keep original unless you pick a preset, a percentage, or an exact Width × Height.
4. Convert and Download: Click Convert and save the .wtv file. Uploads travel over an encrypted connection, run on our servers, and are deleted automatically after a few hours — no sign-up, no watermark.

Frequently Asked Questions

What is a WTV file, exactly?

It is the container Windows Media Center used for recorded television — the successor to the earlier DVR-MS format. A real recording holds the broadcast video and audio streams plus programme metadata from the electronic programme guide. Media Center shipped as part of Windows through the 8.1 generation and was not carried forward into Windows 10, which is why the format is now firmly legacy.

Which codec ends up inside the WTV file?

H.264. This page exposes no video codec picker — no codec option is offered for the WTV container — so the encoder falls back to H.264 and the muxer writes it into the WTV wrapper using a format tag. That is worth knowing because genuine Media Center recordings normally carried MPEG-2 video with AC-3 audio, which is also what FFmpeg's WTV muxer defaults to when nothing else is specified. If a particular Windows-era tool refuses the file, an MPEG-2 based target such as APNG to MPG is the closer match to what that software expects.

Why does the WTV have no audio?

Because the source has none. An animated PNG is an image format with no sound, so the file is muxed video-only and the audio codec control is hidden for image sources. Real recorded-TV files always carry audio, so a handful of strict ingest tools may complain about a video-only stream; mux a silent audio track in with your own tooling if yours does.

Can the WTV keep my APNG's transparent background?

No. The encode produces opaque video and the transparency is composited onto the Background Color first — white unless you change it. If preserving the alpha channel matters more than the container, stay in image formats: APNG to GIF keeps the animation and a transparent colour index, while APNG to WebP gives you the first frame as a still image with a full 8-bit alpha channel.

Does the conversion keep every frame of the animation?

Yes. An animated PNG is detected as a frame sequence and decoded like a video source, so all frames are re-encoded with the timing stored in the file. There is no per-image duration setting on this page because the animation supplies its own.

What can actually play a .wtv file?

Windows Media Center, on the Windows versions that shipped with it, and any player built on FFmpeg — VLC and mpv both open WTV on Windows, macOS, and Linux. Browsers do not play it, standalone Windows Media Player is unreliable with it, and video editors generally will not import it. That narrow playback story is the main reason to prefer APNG to MP4 unless a Media Center workflow is specifically what you are targeting.

Should I be using WTV at all, or a different container?

Use WTV only when something downstream insists on a recorded-TV file. For general playback and sharing, MP4 is the right answer; for a modern web page, APNG to WebM is smaller and plays inline; for broadcast and streaming pipelines, APNG to TS produces the MPEG transport stream those systems expect. All three are far better supported than WTV.

Can I convert an existing recorded TV show out of WTV?

Only if it is unencrypted. Recordings captured from protected broadcast channels are DRM-restricted by design, and no converter can re-encode them without the licence — a limitation of the recording, not of the tool. Recordings from free-to-air sources have no such restriction.

What happens to my uploaded APNG file after the conversion?

It is uploaded over an encrypted (TLS) connection, converted on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public. To turn the same animation into other image formats, the APNG converter hub collects those conversions in one place.
