Convert FLAC to MP3

FLAC to MP3 converter that runs entirely in your browser. 100% free, no signup, no upload — your files never leave your device. One-click batch conversion.

FLAC is lossless (half the size of WAV with identical audio) — great for archiving, awkward for phones and cars. Converting FLAC to MP3 makes the file play anywhere at about 1/8th the size; pick 320 kbps for near-no audible loss or 128 kbps for voice.

About formats

FLAC

FLAC (Free Lossless Audio Codec) is an open-source lossless audio format that compresses audio without discarding any information, typically reducing file size by 50-60% compared to WAV while allowing perfect reconstruction of the original signal. FLAC is the preferred format for high-fidelity music archives and audiophile collections.

MP3

MP3 (MPEG-1 Audio Layer III) is the most popular lossy audio compression format, designed by the Moving Picture Experts Group. It drastically reduces file size while preserving near-CD quality by discarding sounds that are inaudible to most listeners. MP3 is supported by virtually every audio player, device, and platform ever made.

Frequently Asked Questions

Is converting FLAC to MP3 free?
Yes. This FLAC → MP3 converter runs entirely in your browser and is completely free — no account, no credits, no watermark.
Which devices and platforms can I use to convert FLAC to MP3?
Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.
Are my FLAC files uploaded to a server?
No. Files never leave your device. The entire FLAC → MP3 conversion runs locally in your browser, so your data stays private.
Can I convert multiple FLAC files at once?
Yes — batch conversion is supported. Add as many FLAC files as you like and convert them to MP3 in one pass, then download the results together.
What is the maximum file size?
There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.
Will I lose quality converting FLAC to MP3?
Yes — MP3 uses lossy compression, so the converted file will discard some information from your lossless FLAC. Choose a high quality setting to minimise the visible loss.
Does MP3 support transparency?
No — MP3 has no alpha channel. Transparent areas of your FLAC file will be filled with a solid background colour in the converted file.
Will the converted MP3 file be smaller than the FLAC?
Usually yes. Converting from a lossless or uncompressed format to a lossy one dramatically reduces file size. Typical savings range from 50% to 90%, depending on the quality setting you choose.
