About this conversion
Only the audio encoding changes: the recording is decoded and encoded again in your browser.
How it works
The audio is converted by ffmpeg compiled to WebAssembly. It loads only when you choose a file and runs in a background thread.
Your browser can
- Built-in image codecs
- Hardware video (WebCodecs)
- Multiple threads
- Create AVIF natively
If something is missing, the conversion takes a little longer but still works.
About WAV (Waveform Audio File Format)
WAV stores audio uncompressed, so it keeps every sample exactly but needs about 10 MB per minute of stereo sound.
- Recording and editing
- Exchanging audio with studios
- Sound effects in games and apps
About FLAC (Free Lossless Audio Codec)
FLAC compresses audio without any loss, typically to about half the size of a WAV file.
- Bit-perfect copy of the original
- Roughly 40 to 60 percent smaller than WAV
- Open, royalty free and well tagged

Frequently asked questions
Are my files uploaded to a server?
No. The conversion runs entirely in your browser with local code. Your files never leave your device, and there is no upload.
Is there a file size limit?
There is no limit on our side, but your browser memory is. Images work for very large files; for videos, files above a few hundred megabytes can fail on devices with little memory.
Will the quality suffer?
That depends on the target format and settings. Use the quality option to balance size and detail; lossless targets keep everything the source contained.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox and Safari. Fast hardware paths are used where available, with a compatible fallback otherwise.
