Compress MP3

Upload an MP3 file and get a smaller version in seconds — free, no account required.

FloxerFile shrinks MP3 files by re-encoding them at a lower 96kbps bitrate directly on our servers. Useful for email attachments, saving storage, or faster uploads. No software to install, no data stored after conversion.

Frequently asked questions

Is FloxerFile free to use?
Yes. Compressing MP3 files is completely free, with no account required. You can compress files up to 30 MB.
Will this reduce audio quality?
Yes — re-encoding an already-compressed MP3 at a lower bitrate loses some additional quality (a second lossy pass). It's a real trade-off between file size and fidelity, most noticeable on complex music, less on speech.
What bitrate is the output?
Files are re-encoded at 96kbps, which keeps speech and most music clearly listenable at a much smaller size.
Are my files kept private?
Your files are processed on our servers solely to perform the compression. They are deleted automatically once the download is complete and are never shared or stored long-term.
