Convert FLAC to MP3

Upload a FLAC file and convert it to MP3 in your browser.

Why convert FLAC to MP3?

FLAC stores audio using lossless compression, but its files are often larger than MP3 files.

This tool converts your FLAC into a 320 kbps MP3. The smaller output is more convenient for portable devices, sharing, and applications that do not support FLAC.

MP3 uses lossy compression, so some audio information is permanently discarded during conversion. Keep the original FLAC if you may need the lossless version later.

What to expect

The output is a constant-bitrate MP3 encoded at 320 kbps, the highest standard MP3 bitrate. It uses approximately 2.4 MB per minute of audio, although metadata and file overhead may make the final file slightly larger.

MP3 is widely supported by phones, computers, car stereos, portable audio players, and audio applications.

Common reasons to convert FLAC to MP3

Create smaller copies of a music library for a phone, prepare audio for an older player or car stereo, or share a file with someone whose software does not support FLAC.

Frequently asked questions

Does converting FLAC to MP3 reduce quality?

Yes. FLAC is lossless, while MP3 uses lossy compression and permanently removes some audio information.

The tool uses 320 kbps to limit compression, but the MP3 is not identical to the FLAC.

Will I hear a difference?

That depends on the recording, playback equipment, listening environment, and listener.

A 320 kbps MP3 applies less compression than lower-bitrate MP3 files, but the conversion is still lossy.

What bitrate will the MP3 use?

The output is encoded as a 320 kbps constant-bitrate MP3. This setting is fixed and does not depend on the FLAC file's bitrate or compression level.

What happens to multichannel or high-sample-rate FLAC files?

Mono and stereo FLAC files using an MP3-supported sample rate normally keep their original sample rate and number of channels.

Multichannel FLAC files are converted to stereo. Files using an unsupported high sample rate are resampled to 48 kHz.

Can I convert the MP3 back to FLAC to restore the original quality?

No. Converting the MP3 back to FLAC will not restore information discarded during MP3 encoding. It will produce a lossless file containing the already compressed MP3-quality audio.

Keep the original FLAC if you may need the lossless version later.

How much smaller will the MP3 be?

The amount saved depends on the FLAC file's duration, sample rate, bit depth, number of channels, and compression ratio.

The resulting 320 kbps MP3 uses approximately 2.4 MB per minute.

Is my FLAC file uploaded?

No. Your FLAC file is processed in your browser and is not uploaded to a server. Very large files may still be limited by the memory and processing resources available on your device.
