FAQ

Is FLAC really lossless compared to MP3 or AAC?

Yes. FLAC compresses without discarding data, so the audio you download is bit-for-bit identical to the source track.

What sample rates and bit depths are supported?

We keep the original sample rate (up to 192 kHz) and 16- or 24-bit depth by default. You can down-sample in Advanced settings.

Can I keep album art or metadata?

Artwork isn’t embedded automatically, but you can add tags later with any FLAC editor such as Mp3tag or MusicBrainz Picard.

Is there a maximum upload size?

Files up to 100 MB are accepted. Larger videos convert more slowly but follow the same secure workflow.

Will the converter split multi-channel audio?

No. We export the original channel layout—stereo, 5.1, or more—directly into the FLAC file without down-mixing.

How is my privacy protected?

Uploads travel over HTTPS, are processed only in volatile memory, and are auto-deleted minutes after conversion.
