ConvertWhat happens when you convert FLAC to OGG
- OGG is lossy, so files are far smaller. Pick a bitrate; the default 128 kbps sounds great for music.
- Opus works at 48 kHz, so audio is resampled to 48 kHz if needed.
- Mono and stereo are kept (or choose either); surround sound is mixed down to stereo.
- Tags such as title, artist and cover art aren't copied yet.

Frequently asked questions
Is it safe to convert my files here?
Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.
Is it free? Are there limits?
It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.
Can I convert many FLAC files at once?
Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
Will converting FLAC to OGG reduce quality?
OGG removes sounds most people can't hear to make the file smaller. At the default bitrate most listeners won't notice a difference; pick a higher bitrate to be safe.
Which bitrate should I choose?
For music, 192 kbps MP3 or 160 kbps AAC sounds near-identical to the original, and Opus sounds great at 128 kbps. For speech and podcasts, 64–96 kbps is plenty.
Are tags and cover art kept?
Not yet. The sound is converted, but title, artist and album art aren't copied.
