Your files never left your device
No. Everything runs in your browser - your file never leaves your device. How this is verifiable
An audio file often carries more information than what is audible at first glance: the recording software, a device name, sometimes even a comment field with the real name of the author or the original file path. Before a voice memo, an interview recording or a self-produced track is shared onward, it is worth a look at these invisible fields - and this tool removes them with one click.
Technically, this deliberately involves NO re-encoding: ffmpeg copies the audio data stream bit-for-bit unchanged into a new container and only deletes the container metadata (ID3 tags for MP3, Vorbis comments for OGG, MP4 atoms for M4A, FLAC comment blocks). That is not only faster than re-encoding, it also guarantees the sound itself does not change - no second lossy pass, no quality loss.
The process runs entirely locally in the browser via ffmpeg.wasm. Several files can be cleaned in one batch; each keeps its original format (an MP3 stays MP3, a FLAC stays FLAC).
| Input formats | MP3, FLAC, M4A, OGG |
|---|---|
| Auto-conversion | WAV, MP4 |
| Output format | MP3 |
| Batch processing | Yes |
| Processing | Locally in your browser (WebAssembly) |
| File upload | None |
Limitations: Supports MP3, FLAC, M4A and OGG - other containers are not offered. An embedded cover image also counts as metadata and is removed along with the rest. The result keeps exactly the source format (no format conversion). If one file in a batch fails (e.g. no audio track), the rest are still cleaned.
No, everything runs locally in the browser.
No. The audio data stream is copied unchanged (stream copy), only the metadata disappears.
Yes, an embedded cover counts as metadata and is removed as well.
Because there is no re-encoding - only the metadata is removed, the audio is only copied, not recalculated.
