It sounds backwards, but WAV to WEBM is a real need: plenty of platforms and tools only accept video, so Flippy re-packs your WAV audio inside a WEBM wrapper. Where WEBM accepts your WAV'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 WAV to WEBM job: raw voice recordings and studio session exports, bound for embedding on the open web, royalty-free.
WAV is audio with nothing taken away: every sample intact, every megabyte accounted for. It was born in 1991, Microsoft and IBM, and its real weak spot is being carried around: it refuses to shrink.
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 WAV 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 WAV to WEBM: none to pick. Where the WEBM container accepts your WAV's audio codec, the stream is copied bit for bit; where it doesn't, Flippy re-encodes it once and leaves the levels alone.

| Weak spot | being carried around: it refuses to shrink | life outside the browser: editors, TVs and Apple devices get picky |
| Typical size | about 10 MB per minute at CD quality: ten times the size of an MP3 | 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 WAV |

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 WAV behind: WEBM simply opens in more of the places that matter.
Seconds for most WAV 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.
