How to convert FLAC to MP3

MP3 plays on every phone, car stereo, speaker and media player, which makes it the safest format for sharing audio. This tool decodes the FLAC with your browser's audio engine and encodes MP3 locally with the LAME MP3 encoder compiled for the web, so the file never leaves your device.

Step 1: Choose your FLAC file
Drag and drop a .flac file onto the converter or click to browse. It works on desktop, tablet and phone.
Step 2: Choose the quality
The audio is decoded and re-encoded on your device.
Step 3: Download the MP3
Save each result individually, or download everything as a single ZIP when you convert several files.

Good to know

The default 192 kbps is transparent for most listeners; choose 320 kbps for music archiving or 128 kbps for speech and podcasts.
Decoding uses your browser's built-in codecs. Chrome and Edge support the widest range of formats.

About the formats

What is FLAC?

FLAC (Free Lossless Audio Codec) is an open, royalty-free audio format maintained by the Xiph.Org Foundation. It compresses audio losslessly: the decoded sound is bit-for-bit identical to the original, yet files are noticeably smaller than WAV. It supports high resolutions, multichannel audio and metadata tags such as artist and cover art.

Use FLAC to archive CDs, store a music library in full quality or download high-resolution releases. It is ideal when you want smaller files than WAV without any loss. For phones with limited storage or players without FLAC support, a copy in AAC or MP3 is more practical.

What is MP3?

MP3 (MPEG-1 Audio Layer III) is a lossy audio format developed largely at the Fraunhofer Institute and standardised by MPEG in the early 1990s. It removes sounds that human hearing is unlikely to notice, shrinking files dramatically. Quality depends on the bitrate: higher bitrates sound closer to the original. Its patents have expired and virtually every player, car stereo and browser supports it.

Use MP3 when compatibility is the priority: podcasts, music for older devices, audio for websites or files you send to anyone. For archiving or editing, keep a lossless original such as WAV or FLAC, because each lossy re-encode adds artefacts.

Frequently Asked Questions

Is FLAC to MP3 conversion free?

Yes. It is free, with no watermark, signup or email required. Local conversions have no artificial file-size or daily cap; the practical limit is your device.

Will the MP3 sound the same as the FLAC?

At the default bitrate the difference is inaudible for most people. Choose a higher bitrate if you plan to edit or archive the audio.

Are tags such as title and artist kept?

Metadata tags are not copied by the in-browser encoder; add them afterwards in your music player if needed.

Is it safe to convert flac to mp3 here?

Yes. The work happens on your own device with WebAssembly and browser APIs, so the file is not uploaded at all. You can even disconnect from the internet once the page has loaded.

Do I need to install anything?

No. Everything runs in a modern browser (Chrome, Edge, Firefox or Safari) on Windows, macOS, Linux, Android and iOS. There is no app, plugin or account.
