FLAC to MP3 Converter
Bring lossless FLAC down to a portable MP3 while keeping the option to encode at the maximum 320 kbps.

or choose a file from your device — it is processed in this tab and never uploaded
Accepted: FLAC, FLAC in OGG container, WAV, AIFF
Files stay on your device. There is no upload, no queue and no watermark, so a conversion works even with the network switched off after the page has loaded.
Supported formats & processing

How to use this tool
- Add the FLAC fileThe browser decodes the lossless stream to full-precision PCM.
- Choose the bitrate320 kbps for a transparent portable copy, 192 kbps when storage is tight.
- Keep the sample rateFLAC archives are usually 44.1 or 48 kHz, both of which MP3 supports directly.
- ConvertA five-minute track encodes in a few seconds on a modern laptop.
- Download and compareUse the preview player to A/B the MP3 against the FLAC before deleting anything.
About this tool
FLAC is lossless: the file contains exactly the samples that were recorded, compressed at roughly 50–60 percent of the original size with no quality loss. That makes it the ideal archive format — and an awkward one for a phone with limited storage or a car stereo with no FLAC support.
Because the source is lossless, this is the one conversion where the bitrate you choose genuinely determines the ceiling of what you hear. At 320 kbps the difference from the original is very hard to detect in normal listening conditions; at 192 kbps you save about 40 percent more space at the cost of some high-frequency detail.
Features
- Reads FLAC streaminfo to report the real sample rate, channels and bit depth
- Lossless source means the bitrate choice is meaningful
- Up to 320 kbps, the maximum MPEG-1 Layer III allows
- No re-sampling when the source is already 44.1 or 48 kHz
- Preview player for a direct comparison with the original
- Your FLAC archive is never modified — the tool only reads it
Frequently asked questions
Should I keep the FLAC as well?
Yes if it is your only master copy. Keep the FLAC as the archive and use the MP3 for phones, cars and sharing. Storage is cheap; re-ripping is not.
Is 320 kbps MP3 as good as FLAC?
Not bit-for-bit, but for most listeners on most equipment the difference is inaudible. If you need mathematical certainty, keep FLAC or use a lossless-capable player.
Why did the converter report a different bit depth?
MP3 stores decoded samples at 16-bit internally, so a 24-bit FLAC master is reduced to 16-bit during encoding. That is inherent to the format, not a bug.
Can I convert several FLAC files together?
Convert them one at a time, or use the audio joiner to combine tracks into a single MP3 — useful for live albums and DJ sets.
