Question 1

Which audio formats are supported?

Accepted Answer

Convert between MP3, WAV, OGG, AAC (saved as .m4a) and FLAC. MP3, OGG and AAC are compressed (you choose the bitrate); WAV and FLAC are lossless, so the bitrate option is hidden for them. Drop in any common audio file — including M4A, Opus and more — and pick your target.

Question 2

Is my audio uploaded anywhere?

Accepted Answer

No. Conversion runs entirely on your device — your audio is never uploaded. The only network request is a one-time download of the media engine (about 32 MB), which is then cached. Your file always stays local, so the tool is on-device but not “fully offline”.

Question 3

What’s the difference between lossless and compressed formats?

Accepted Answer

WAV and FLAC are lossless — they keep every detail (FLAC also compresses, so it’s smaller than WAV with identical quality). MP3, OGG and AAC are lossy: they shrink the file by discarding some inaudible detail, and a higher bitrate keeps more of it. Converting a compressed file to a lossless one can’t restore quality that was already lost — it just makes a bigger file.

Question 4

Will converting reduce the quality?

Accepted Answer

Converting to WAV or FLAC preserves the quality you have. Converting to a lossy format (or re-encoding one lossy format to another) discards a little detail each time, so for the best result convert from the highest-quality source you have and choose a higher bitrate.

Question 5

Is it free and private?

Accepted Answer

Completely free, with no sign-up or watermark, and everything runs in your browser — your audio never leaves your device.
