FLAC to MP3 Converter
Convert FLAC to MP3 at up to 320 kbps and take your lossless albums to the car, the gym or any player that refuses FLAC. Drop a whole album or a folder of them; title, artist and album tags are copied, and 24-bit or high-resolution files are handled automatically. The music is converted in your browser, so nothing is uploaded and there is no size cap.

How to convert FLAC to MP3
Step 1: Drop your FLAC files on the box above. A whole album, or several, is fine.
Step 2: Keep Bitrate at 320 kbps for the best MP3 quality, or choose 192 kbps to save space.
Step 3: Press Convert. Each track keeps its title, artist and album tags.
Step 4: Download the MP3s as one ZIP and copy them to your player or phone.
Good to know
Settings explained
- Bitrate
- 128 kbps is fine for speech, 192 kbps for music, 320 kbps is the MP3 maximum.
- OGG codec
- Godot, Unity and older players need Vorbis. Vorbis uses the FFmpeg engine (≈31 MB, downloaded once).
- Opus: Smaller
- Vorbis: Games, older players
Formats
Batch-friendly: add many files and they are processed one after another — if one fails, the rest still finish.
How it runs
- Hardware video engine
- Video is decoded and encoded by your device’s media hardware through WebCodecs — usually several times faster than real time.
- FFmpeg (when needed)
- Older formats and a few filters use FFmpeg compiled to WebAssembly. It downloads once (about 31 MB) the first time it is needed and is cached for offline use.
FLAC vs MP3: is there a big difference?
In file size, yes; in what you hear, usually not. FLAC keeps every bit of the original recording and is usually two to three times the size of a 320 kbps MP3. A well-encoded 320 kbps MP3 is very hard to tell from FLAC on phones, earbuds and car stereos. FLAC is the archive; MP3 is the copy you carry.
| FLAC | MP3 (320 kbps) | |
|---|---|---|
| Compression | Lossless: decodes to the exact original | Lossy: removes sound you are unlikely to hear |
| 45-minute album (CD quality) | About 240–330 MB | About 108 MB |
| Hi-res (24-bit, 96 kHz) | Supported | Becomes 48 kHz (the MP3 maximum) |
| Plays in Apple Music, many car stereos | Often not | Yes |
| Re-convert later without loss | Yes | No |
What is a FLAC file?
A FLAC file (Free Lossless Audio Codec) is audio compressed without losing anything, in the same way a ZIP compresses a document: decode it and you get back the exact samples of the original recording. It is open and royalty-free, which is why lossless download stores, CD-ripping software and many audiophile players use it.
The catch is support. Apple Music and iTunes do not import FLAC, many car stereos and older players skip it, and lossless files fill a phone quickly. Converting a copy to MP3 solves all three.
Does converting FLAC to MP3 lose quality?
Yes, technically, because MP3 is lossy; in practice, at 320 kbps the loss is extremely hard to hear. Keep the FLAC files as your master copy so you can make new MP3s, or AAC or Opus files, whenever you need them without stacking losses.
| Bitrate | Size per album hour | Choose it when |
|---|---|---|
| 320 kbps (default) | 144 MB | You want the best MP3 and space is not tight |
| 256 kbps | 115 MB | Good headphones, a bit less space |
| 192 kbps | 86 MB | Phone or car listening, large libraries |
| 128 kbps | 58 MB | Audiobooks or spoken word ripped to FLAC |
Hi-res, 24-bit and surround FLAC
High-resolution FLAC converts without extra settings. The MP3 format tops out at 48 kHz, so 96 and 192 kHz files become 48 kHz MP3s and 88.2 or 176.4 kHz files become 44.1 kHz, using a high-quality resampler. Bit depth does not exist in MP3, so 24-bit sources simply give the encoder more detail to start from. Multichannel FLAC, such as a 5.1 mix, is mixed down to stereo, because MP3 holds two channels at most.
Why convert FLAC to MP3 here
- Whole albums at once. Drop every track; they are converted in turn and saved as one ZIP.
- Tags kept. Title, artist and album come along, so your player sorts the MP3s correctly.
- No upload of big files. A lossless album is hundreds of megabytes; here it never leaves your computer.
- 320 kbps by default. The page starts at the MP3 maximum because a lossless source deserves it.
Tips & troubleshooting
Want smaller files without MP3’s compatibility limits? The audio converter can turn FLAC into M4A (AAC) or Opus instead.
Need an editable copy rather than a smaller one? Convert FLAC to WAV in the audio converter; it stays lossless.
Albums at different loudness? After converting, normalize audio brings every track to the same level.
Converting from WAV or AIFF masters instead? Use WAV to MP3 or AIFF to MP3.
FLAC to MP3 Converter FAQ
Is a 320 kbps MP3 as good as FLAC?
Not technically, since FLAC is lossless and MP3 is not, but most listeners cannot reliably hear a difference on everyday equipment. Keep the FLAC as your archive and use the 320 kbps MP3 for listening.
Does converting FLAC to MP3 lose quality?
Yes, a little, because MP3 discards detail to save space. At 320 kbps the loss is very small. Never delete your FLACs after converting: going back from MP3 to FLAC cannot restore what was removed.
Are artist and album tags kept when converting FLAC to MP3?
Yes. Title, artist and album tags are copied from the FLAC into the MP3’s ID3 tags, so music players and car stereos list the tracks correctly.
Can I play FLAC on an iPhone?
The Files app and some third-party players can, but the Apple Music app does not import FLAC. Converting to MP3 (or M4A) is the simple way to get lossless rips into your iPhone’s music library.
How do I convert FLAC to MP3 on a Mac?
Open this page in Safari or Chrome, drag the FLAC files from Finder onto the drop zone and press Convert. The MP3s are saved to Downloads. The Music app cannot do it, because it does not import FLAC in the first place.
