Why convert FLAC to MP3?
You have a large FLAC file (studio recording, software export, CD archive) and you want a small MP3 to listen to on your phone, send by email or publish online. Choose 256 or 320 kbps to keep excellent quality.
How to do it, step by step
- Drop your FLAC fileinto the area at the top of the page (or several files at once). On mobile, tap the area and pick the file from your apps.
- Check the output format: MP3 is already selected. For music, 192 kbps is transparent for most listeners and 320 kbps gives the maximum. For voice (memos, podcasts, lectures), 128 kbps is more than enough and halves the file size.
- Start the conversion.The FFmpeg engine loads once (≈ 10 MB), then each file is processed in a few seconds without leaving your device.
- Download your MP3, directly or as a .zip if you converted several files. The name and metadata (title, artist, cover art) are preserved.
The FLAC format (Free Lossless Audio Codec)
FLAC compresses audio with zero loss: the file is 40 to 60% the size of the original WAV but reproduces exactly the same sound. It is the format of choice for audiophiles and music archives. It is free, open, and supports metadata and cover art.
- Quality identical to the original
- Free and open format
- Supports tags and cover art
- Files 5 to 10 times larger than an MP3
- Not played by Apple devices without a third-party app
The MP3 format (MPEG-1/2 Audio Layer III)
MP3 is the most universal audio format in the world. It plays on absolutely everything: car stereos, phones, TVs, game consoles, MP3 players, browsers, editing software. Its compression is slightly less efficient than AAC, but its total compatibility makes it the safe choice for sharing an audio file.
- Compatible with 100% of devices
- Small file size
- Patent-free since 2017
- Less efficient compression than AAC/Opus
- Irreversible quality loss at low bitrates

Frequently asked questions
Does converting FLAC to MP3 lose quality?
MP3 is a lossy compressed format: a conversion always involves re-encoding. At 192 kbps or higher, the difference is inaudible in the vast majority of cases. Just avoid chaining several successive conversions.
Is the FLAC to MP3 converter free?
Yes, with no limit on the number of files, no sign-up and no watermark. Each file can be up to 200 MB.
Are my FLAC files uploaded to the internet?
No. The FLAC to MP3 conversion is performed by FFmpeg directly in your browser (WebAssembly). Your files never leave your computer or phone.
How do I convert FLAC to MP3 on iPhone or Android?
Open this page in Safari or Chrome, tap the drop area, select your FLAC file (from Files, Voice Memos, Downloads or WhatsApp), then tap "Convert". The MP3 downloads to your files.
Can I convert several FLAC files at once?
Yes, add all your files in one go. They are converted one after another and a button lets you download everything as a .zip archive.
