Free tools for your next audio edit
Convert FLAC to MP3. Keep your audio local.
Create an MP3 from a compatible short FLAC on your device. Choose a bitrate, preview the result and download without an account or audio upload. You can also choose a PCM16 WAV working copy.
Convert FLAC to MP3
Free · localChoose a supported FLAC and prepare an audio file. No audio upload or account required.
FLAC can preserve audio losslessly, but this converter decodes and resamples it and produces a new lossy MP3 or 16-bit PCM WAV. The WAV may not preserve higher bit depth or the original samples. Keep the FLAC. Browser codec support varies. This tool does not separate voices or music, copy tags/artwork, preserve higher bit depth or source codec padding, remove noise, or isolate sound. Input and output must each fit 50 MiB and five minutes; an oversized output is rejected rather than cut. MP3 is a new lossy encode and may add delay or padding. Encoder credits and source are below.

How to convert FLAC to MP3
- 01 / OPEN
Choose a FLAC file
Select a compatible local FLAC no larger than 50 MiB and five minutes. Browser decoding support varies.
- 02 / CONVERT
Choose a bitrate
MP3 is selected by default. Choose 128, 192 or 320 kbps and convert. Decoded audio must be mono or stereo; the output must also fit 50 MiB.
- 03 / LISTEN
Preview and download
Listen to the actual MP3 and check its length before downloading. Keep the FLAC as your original lossless source.

What happens when you convert FLAC to MP3?
FLAC is lossless for the audio it encodes; MP3 discards information to make a smaller encoded file. This converter decodes the FLAC in your browser at 48 kHz and makes a new MP3. Compare quiet passages, dense music and the ending against the original. Higher bitrates generally use more space but cannot recover detail missing from the source.
MP3 encoding may introduce delay or padding, so check alignment if the output will return to a video or multitrack project. The converter does not copy original tags or artwork. Keep the FLAC if you need a lossless archive or plan to make other delivery copies.
You can select WAV above to create 16-bit PCM at 44.1 or 48 kHz. This is a convenient working copy, not a guaranteed lossless FLAC-to-WAV conversion: resampling and reducing a higher bit depth can change the decoded samples. WAV must also fit the 50 MiB output limit. See the FLAC and WAV guide for sample-preserving workflows.
If conversion fails
Check the file and browser
First play the source. The file must fit 50 MiB and five minutes, decode to mono or stereo, and produce an output no larger than 50 MiB. Browser support varies. For a longer, multichannel or unsupported file, try a desktop audio converter and verify the exported file. Renaming the extension does not convert audio.
For a compatible OGG file, use OGG to MP3. To test isolating a voice in a mixed recording, first prepare a supported file and use the separate voice isolator; AI downloads require an account and credits.
MP3 encoder credits
Built with the LAME encoder via lamejs.
The optional MP3 download uses lamejs 1.2.1 by Alex Zhukov, a JavaScript port of the LAME MP3 encoder. Its unmodified script is served separately. See the attribution and source notes, upstream license notice, LGPL-3.0 and GPL-3.0 texts, and complete upstream source package.
A few useful answers
Free FLAC to MP3 converter questions
How do I convert FLAC to MP3?
Choose a compatible local FLAC up to 50 MiB and five minutes, select an MP3 bitrate, then convert, preview and download. Decoded audio must be mono or stereo and the output must also fit 50 MiB. Browser codec support varies.
Does this upload my audio?
No. The browser reads and converts the selected file locally. Download the result before leaving the page.
Is the MP3 as lossless as the FLAC?
No. MP3 is a new lossy encode at 128, 192 or 320 kbps and can discard detail. The browser decodes and resamples the source to 48 kHz. Keep the original FLAC.
Can I convert FLAC to WAV instead?
Yes. Select WAV to create 16-bit PCM at 44.1 or 48 kHz. This working copy may be resampled or reduced in bit depth and is not guaranteed to preserve the original samples. Input and output limits still apply.
Why can't my FLAC file be converted?
Your browser may not decode the file, it may be empty or exceed the size or duration limits, or the decoded audio may have more than two channels. Try a compatible browser or desktop converter.
