FLAC, WAV, ALAC (m4a container) - these are lossless. Useful for archival or editing.

MP3: VBR q:a 2 (~190 kbps). AAC / M4A: 192 kbps. Opus: 96 kbps (modern codec, better quality-to-size ratio). FLAC: lossless. WAV: uncompressed 16-bit PCM.

Yes - ffmpeg preserves channel count. Upload 5.1, get 5.1 back (if the target format supports it).

Is the conversion safe?

Yes. Small files convert inside your browser - never uploaded. Larger ones land on our server temporarily and are wiped automatically: 200 MB after 10 min, 100 MB after 20 min, 50 MB after 30 min, smaller after one hour. You can also delete them instantly after download.

Yes - 200 MB max per file. Larger files get rejected for performance and cost reasons.

Do you preserve original quality?

Depends on the pair. Lossy compression (e.g. JPG, MP3) always trims something - we set sensible defaults. Lossless (FLAC, PNG, ZIP) keeps everything 1:1.

Do I need an account?

No. The converter works right away - no signup, no login, no payment.

Fine. Tools run on free software (ffmpeg, LibreOffice, Calibre, ImageMagick). Your files stay yours, no claims from us.

What if the conversion fails?

You get a specific error. Common causes: corrupt source, encrypted format, file too large, or an unusual variant. Open in the source app, save again, re-upload.
