Add your APNG file
Drop one or more .apng files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
APNG to WMV
Converting a .apng image to .wmv re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.

Converting a .apng image to .wmv re-encodes the pixels for a different balance of size, quality, and support. An .apng file is an animated extension of PNG: full 24-bit color with 8-bit alpha per frame, in a stream that plain PNG decoders read as a normal still image. It delivers the smooth, semi-transparent animation that GIF's 256-color palette never could, and it is the format behind many messaging-app sticker packs.
A .wmv file contains Windows Media Video, Microsoft's proprietary codec family, almost always wrapped in an ASF container. The extension was everywhere on Windows XP-era PCs, from downloaded clips to Movie Maker exports, but it has faded as MP4 became universal. For this route the practical draw is excellent support across legacy Windows software and vC-1 encodes hold up reasonably well for their age — balanced against effectively abandoned by Microsoft itself, which is worth knowing before you commit a large batch.
Why convert APNG to WMV?
The practical trigger for this conversion is usually a mismatch: with .apng, files grow quickly for long or high-motion animations, where animated WebP/AVIF or video compress far better. Switching to .wmv buys you excellent support across legacy Windows software, which is why it is the better fit for playing old Movie Maker projects and family archives. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
APNG vs WMV at a glance
| Aspect | Animated PNG (.apng) | Windows Media video (.wmv) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Container — quality depends on the codecs and settings inside |
| How it stores data | adds three chunk types to PNG: acTL (animation control), fcTL (frame control), and fdAT (frame data) | aSF container carrying WMV1, WMV2, or WMV3 (VC-1) video, typically with WMA audio |
| Strongest at | animated stickers (Apple's iMessage and LINE both build on APNG) | playing old Movie Maker projects and family archives |
| Weak spot | files grow quickly for long or high-motion animations, where animated WebP/AVIF or video compress far better | effectively abandoned by Microsoft itself |
Pick WMV as the output
Select .wmv in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if WMV is selectable, the route is real and validated.
Convert on your device
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid WMV file. Outputs keep the original filename with the .wmv extension.
APNG to WMV questions, answered
Will converting APNG to WMV lose quality?
Since apng is lossless-oriented and wmv is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .wmv itself requires.
Is it private to convert APNG files here?
Yes — the .apng file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Where will the WMV file work?
Windows 10 and 11 still play .wmv out of the box, but macOS dropped support after the QuickTime plugin era ended, and no browser or mobile OS will touch it. Conversion to MP4 is required for web or cross-platform use.
Will the WMV file be bigger or smaller than my APNG?
It depends on the content: aSF container carrying WMV1, WMV2, or WMV3 (VC-1) video, typically with WMA audio. Convert one representative file first and compare before batch-processing a large set.
