Need help?Convert WTV to APNG Online
WTV is the Windows Media Center recording container, holding a full broadcast-length TV program with MPEG-2 video and AC-3 or MPEG audio. APNG (Animated PNG) is a short, silent, looping image — the kind of clip you embed in a forum post, a chat, or a web page. Converting WTV to APNG means picking a slice of that recording and rendering it as a lossless animated still: every pixel preserved, no sound, plays automatically wherever a normal PNG loads.
This pairing is niche by design. You are not archiving a whole show as an APNG — a one-hour recording would produce an enormous file. The realistic use is a short highlight: a few seconds of a recorded broadcast turned into a crisp, repeatable animation for sharing or documentation.

APNG Format at a Glance
| Property | Value |
|---|---|
| Full name | Animated Portable Network Graphics |
| Origin | Mozilla extension to the PNG spec (2008), maintained alongside PNG |
| Compression | Lossless (DEFLATE), no quality loss between frames |
| Color | 24-bit truecolor plus an 8-bit alpha channel |
| Audio | None — APNG is image-only |
| Native browser support | Chrome 59+, Firefox 3+, Safari 8+, Edge 79+ (~94-95% of users) |
| Fallback | Browsers without APNG show only the first frame as a static PNG |
| Best for | Short, sharp, looping clips where exact pixels and smooth alpha matter |
How to Convert WTV to APNG
- Upload Your WTV File: Drag and drop your
.wtvrecording onto the page or click "Upload." Files travel over an encrypted connection to our servers and are deleted automatically after a few hours. - Set the Framerate: Pick a value under "Framerate" — the default is 10 FPS, a good balance of smoothness and file size. Higher rates look smoother but multiply the frame count and the final size.
- Adjust Image Quality and Resolution: Use "Image quality (%)" and "Image resolution" (keep original, a preset, or a custom width and height) to control sharpness versus size; "Colors" lets you reduce the palette with dithering if you need a smaller output.
- Convert and Download: Click "Convert." No sign-up, no watermark, and the result is yours to download.
Frequently Asked Questions
Why is my APNG so much larger than a GIF would be?
Because APNG is lossless and keeps full 24-bit color, it stores far more data per frame than a 256-color GIF. In our testing, a 5-second clip at 10 FPS and 480p typically lands a few megabytes as APNG versus a smaller but visibly banded GIF. APNG wins on fidelity; GIF wins on raw size and universal support. Trim the clip short, lower the framerate, or reduce the resolution to keep APNG files manageable.
Will the audio from my WTV recording be kept?
No. APNG is an image format with no audio track, so the Dolby Digital or MPEG sound in your WTV file is dropped during conversion. If you need the sound, convert to a video format instead — for example, the WTV to MP4 converter keeps both picture and audio.
Should I use APNG, GIF, or animated WebP for a recorded-TV clip?
APNG gives the best visual quality and true alpha transparency, and roughly 94-95% of browsers display it natively (the rest show the first frame). GIF is capped at 256 colors but plays absolutely everywhere. Animated WebP usually produces the smallest file at similar quality but is unsupported in a few older environments. For a sharp, short broadcast highlight where quality matters, APNG is a strong pick; for maximum reach, GIF via the WTV to GIF converter is safer.
Can I convert an entire one-hour recording to a single APNG?
You can, but you almost certainly should not. APNG stores every frame losslessly, so a full program would produce a file far too large to share or load in a browser. APNG is meant for short loops — pick a few seconds of footage, keep the framerate modest, and you will get a usable file.
Does the broadcast-flag protection on some WTV files affect conversion?
It can. WTV can carry a broadcast flag or other digital rights management on protected recordings, and DRM-locked content cannot be re-encoded. Recordings of free over-the-air channels are usually unprotected and convert normally; copy-protected cable or premium content may be blocked from any format change.
What is the default frame rate and why is it 10 FPS?
The converter defaults to 10 FPS because it keeps the animation reasonably smooth while holding the frame count — and therefore the lossless file size — under control. Source TV is usually 25 or 30 FPS; sampling down to 10 trades a little smoothness for a much smaller APNG. Raise it toward the source rate only if you need fluid motion and can accept a larger file.
Are my uploaded files kept private?
Yes. Your WTV file is uploaded over an encrypted (TLS) connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, the output carries no watermark, and your files are never shared or made public.
