It sounds backwards, but WMA to WEBM is a real need: plenty of platforms and tools only accept video, so Flippy re-packs your WMA audio inside a WEBM wrapper. Where WEBM accepts your WMA's codec the sound crosses over untouched; where it doesn't, it's re-encoded once. The WEBM that comes out is built for embedding on the web without licensing worries.
A classic WMA to WEBM job: aging Windows Media libraries, bound for embedding on the open web, royalty-free.
WMA is Windows' old house band: big in the early 2000s, mostly retired now. It was born in 1999, Microsoft, and its real weak spot is the modern world: Apple devices, browsers and most apps have moved on.
WEBM is video the way browsers like it: open, royalty-free and built to stream. A Matroska-based container restricted to VP8/VP9/AV1 video with Vorbis or Opus audio. That makes it the right destination when what you need is embedding on the web without licensing worries.
Drop your WMA file into the flipper above, or click to browse for it.
Check the output format: WEBM is already selected for you.
Hit Convert, give it a moment, then download your new WEBM.
Settings for WMA to WEBM: none to pick. Where the WEBM container accepts your WMA's audio codec, the stream is copied bit for bit; where it doesn't, Flippy re-encodes it once and leaves the levels alone.
| WMA | WEBM | |

| Best for | keeping aging Windows Media software and old archives happy | embedding on the web without licensing worries |
| Weak spot | the modern world: Apple devices, browsers and most apps have moved on | life outside the browser: editors, TVs and Apple devices get picky |
| Typical size | MP3-ish sizes; the famous 'CD quality at 64 kbps' claim never quite landed | for video content, often smaller than the equivalent MP4: VP9 and AV1 squeeze harder than H.264; wrapping audio alone stays about the size of the WMA |
| Plays on | Windows Media Player and legacy Microsoft software; little else without help. | Every modern browser; hit-and-miss in editing apps and on Apple hardware. |
No. Wrapping audio in a WEBM container doesn't touch the sound itself: it's the same stream in a different box.
About the same, plus a sliver of container overhead. The audio stream is unchanged; WEBM just adds a video-shaped envelope.
Every modern browser; hit-and-miss in editing apps and on Apple hardware. That's the usual reason people leave WMA behind: WEBM simply opens in more of the places that matter.
Seconds for most WMA files: there are no pictures to encode, so wrapping the audio as WEBM is nearly as fast as copying it. Both files auto-delete within an hour.
