How to convert FLAC to MP3
Drop your FLAC files into the box above, or click Choose files. You can add several at once.
Pick a bitrate. 192 kbps sounds transparent to most listeners; 320 kbps is the maximum.
Click Convert to MP3. Files are processed on your device; a few minutes of media usually takes seconds.
Download the MP3 files one by one, or all at once as a ZIP.
Why convert FLAC to MP3?
FLAC keeps music exactly as recorded, but an album takes several hundred megabytes. As MP3 it takes a fraction of that, which matters on a phone, an old player or a USB stick for the car.
Many car stereos, older MP3 players, smart speakers and apps don't play FLAC. MP3 plays on all of them.
Your music library stays on your device: files are converted locally, not uploaded.
FLAC vs MP3
FLAC is lossless: it compresses audio like a ZIP file, and decodes to exactly the original samples. MP3 is lossy and removes detail that's hard to hear, which makes it several times smaller.
Keep the FLAC files as your archive and convert copies to MP3 for listening on the go. At 256 or 320 kbps, MP3 is very hard to tell apart from the original.
| Property | FLAC | MP3 |
|---|---|---|
| Compression | Lossless | Lossy |
| Quality | Exact, bit-for-bit | Very good at 192 kbps and above |
| File size | About half of WAV; several times an MP3 | About 1 MB per minute at 128 kbps |
| Best for | Archiving music and CD rips at full quality | Music and podcasts on any device |
| Support | Android, Windows, macOS, VLC and hi-fi players; some car stereos and older players lack it | Every player, phone, car and browser |
Is it safe?
Yes. FLAC to MP3 runs entirely in your browser. Your files are read and converted by your own device using built-in browser technology, so they are never uploaded to a server and nobody else can see them.
You can check this yourself: open your browser's developer tools, switch to the Network tab and convert a file. No upload requests are made.
Audio is decoded and encoded by your browser, using its built-in media engine and a WebAssembly MP3 encoder. Recordings, voice memos and interviews never leave your device.
Files stay in this tab's memory only until you remove them or close the page.
Frequently Asked Questions
Will the MP3 sound as good as the FLAC?
Not bit for bit, since MP3 is lossy, but at 256 or 320 kbps very few people can hear a difference on normal headphones or speakers. For the best copy, choose 320 kbps.
Does it work with 24-bit and hi-res FLAC?
Yes. Hi-res files (24-bit, 96 or 192 kHz) are converted to standard MP3, which is at most 48 kHz. MP3 can't hold hi-res audio, so the extra resolution is not kept.
How much space will I save?
A CD-quality FLAC is typically 700 to 1,000 kbps. At 320 kbps the MP3 is roughly a third of that; at 192 kbps, about a fifth. The result shows the exact size of each file.
Can I convert a whole album?
Yes. Add up to 500 files at once and download them together as a ZIP.
Is there a file size limit?
Each file can be up to 500 MB. Files are read from disk in small pieces, so long recordings don't need to fit in memory.
