How to convert MP3 to FLAC

Choose an audio file

Choose an MP3 file or drag it onto the page.

Download your audio

Download the new FLAC that was converted from your original MP3 audio.

MP3 input

MP3 is a widely supported compressed audio format.

FLAC output

FLAC preserves quality with lossless compression.

When to use it

Place the decoded MP3 audio in a lossless FLAC container.

Know the tradeoff

FLAC cannot recover detail already removed by MP3 compression, and the output will usually be much larger than the source MP3.

Start with one file

Choose an MP3 audio file or drag it into the page to start.

Frequently Asked Questions

This page is built for MP3 files. If your source file is different, open the matching converter for that format.

FLAC cannot recover detail already removed by MP3 compression, and the output will usually be much larger than the source MP3.

Long clips take more time and memory to process. Very large files can exceed the available browser memory, especially on phones. Try a shorter clip if conversion fails, and keep this tab open until the download is ready.
