FLAC to MP3
Make FLAC to MP3 copies of CD rips and hi-res downloads for your phone, car or old iPod. 320 kbps by default, free, unlimited and nothing uploaded.
Your file is converted in your browser and never uploaded to our servers.
How to Convert FLAC to MP3
- 1
Add one FLAC track
Choose a .flac file from your rip folder or a download you bought. It is read straight from your drive; nothing is sent to a server.
- 2
Keep 320 kbps or step down
320 kbps is preselected because this is music you care about. Pick 192 or 128 kbps only when space on the device is tight.
- 3
Convert and save the MP3
The first conversion loads the converter once, about 9 MB. The new file keeps its name, so 03 Harvest Moon.flac becomes 03 Harvest Moon.mp3.
Why Use This FLAC to MP3 Converter
Your albums stay on your computer
FFmpeg runs inside the browser tab as WebAssembly. A hi-res track of tens of megabytes is converted where it sits instead of crossing your connection twice.
320 kbps out of the box
The top MP3 setting is the default on this page, because the source is lossless and the copy should stay as close to it as MP3 allows.
Tested with 24-bit 96 kHz files
We ran a 24-bit, 96 kHz FLAC through it and got a valid 320 kbps MP3 at 48 kHz, the highest rate the MP3 format allows.
No cap, no account
No sign-up, no watermark and no file count. Convert track after track until the playlist is done.
Keep the FLAC or Carry the MP3? A Side-by-Side
Sizes are approximate: MP3 figures come from the bitrate, FLAC varies with the music.
| FLAC (your archive) | MP3 320 kbps | MP3 192 kbps | |
|---|---|---|---|
| Audio | Bit-for-bit lossless | Lossy, close to the source | Lossy, fine for casual listening |
| One minute, CD quality | Roughly 5 to 7 MB | About 2.4 MB | About 1.44 MB |
| Hi-res 24-bit, 96 kHz | Kept in full | Becomes 48 kHz | Becomes 48 kHz |
| Car stereos and older players | Often not supported | Plays almost everywhere | Plays almost everywhere |
| Apple Music and iTunes library | Will not import | Imports normally | Imports normally |
| Source for future copies | Yes, convert from it again | No, quality only drops | No, quality only drops |
Who Converts FLAC Audio Files to MP3
People who own their music in lossless form and need a copy that plays on the gear they actually use.
CD collectors with ripped libraries
You ripped your discs to FLAC once so you would never rip them again. MP3 copies are the travel version; the rips stay on the drive.
Hi-res store downloads
24-bit albums are big and many phones and players can't use the extra resolution anyway. A 320 kbps MP3 takes a fraction of the space.
Bandcamp and label purchases
You picked FLAC at checkout to have the best copy. Convert the tracks you want on a device and keep the purchase as bought.
Car USB sticks
Many head units read MP3 but skip FLAC. Since file names carry over, numbered tracks keep their album order on the stick.
iPhone and Apple Music
Apple Music and iTunes will not add FLAC files to the library. MP3 imports and syncs like any other song.
Older iPods and MP3 players
Classic players and budget clips often predate FLAC support. An MP3 at 320 kbps works on all of them.
What Happens to 24-bit, 96 kHz FLAC in an MP3
MP3 stores at most 48 kHz, and it has no bit depth in the FLAC sense: the encoder works from the decoded audio and writes a lossy stream. So a hi-res FLAC to MP3 conversion keeps the music but not the hi-res part. In our test, a 24-bit 96 kHz file came out as a 320 kbps MP3 at 48 kHz, resampled automatically.
That is fine for a car, earbuds or a phone speaker. If you want the extra resolution later, for a better DAC or a new player, it is still in the FLAC. A CD rip at 44.1 kHz keeps its sample rate unchanged, and a mono recording stays mono.
Before You Load MP3s on a Phone or Car Stick
- Name files with a leading track number, such as 01, 02, 03, before converting, so players that sort by file name keep the album order.
- Make one folder per album for the MP3s; the converter saves single files to your downloads, not a folder tree.
- Open a few MP3s in your player or a tag editor and check title, artist, album and cover art, since this converter focuses on the audio.
- Convert long or hi-res albums on a desktop browser, because phones with little memory can fail on very large files.
- Check the free space on the stick or phone: a 50-minute album at 320 kbps is about 120 MB.
- Keep the FLAC folder backed up somewhere separate from the device copies.
FLAC to MP3 Mistakes Collectors Make
Mistake: Deleting the FLAC rips once the MP3s play fine.
Do this instead: Keep them. A lost FLAC means ripping the CD again, or buying the album again if it was a download.
Mistake: Making a 192 kbps copy from the 320 kbps MP3.
Do this instead: Go back to the FLAC for every new copy. Encoding an MP3 from an MP3 stacks losses.
Mistake: Renaming song.flac to song.mp3 so the car accepts it.
Do this instead: The extension changes, the audio does not. The stereo will still refuse or skip it; convert it instead.
Mistake: Picking 320 kbps for a 96 kHz file to keep it hi-res.
Do this instead: No MP3 setting keeps 96 kHz. 320 kbps is the best MP3 copy; the hi-res stays in the FLAC.
Mistake: Expecting cover art and tags to be perfect without looking.
Do this instead: Check a couple of tracks after converting and fix what's missing in a tag editor before copying the whole album.
Privacy, Price and Honest Limits
Your music never leaves the device
The FLAC is opened read-only in your browser and only the MP3 is written. Many online converters upload the file to their servers first; this one does not.
Free and unlimited
No account, no daily limit, no watermark and no email asked for. The only download is the converter itself, once, about 9 MB.
What it does not do
It converts one file at a time, so an album means repeating the steps per track. Tags and cover art are not guaranteed to carry over. For a whole library, a desktop batch tool is quicker.
