How to convert FLAC to MP3

Three steps — everything runs in your browser, nothing to install.

  1. Add your FLAC files

    Drag one or more .flac files onto the drop zone, or click it to open a file picker. Your files stay on your device — nothing is uploaded.

  2. Select an MP3 bitrate

    Choose 128, 192, 256, or 320 kbps. 320 kbps is the default and gives you the best quality MP3 allows. Conversion starts automatically once files land.

  3. Download the MP3s

    Grab each file individually or hit the ZIP button to download everything at once. Title, artist, album tags and cover art from the FLAC are already embedded in every MP3.

What happens when you convert FLAC to MP3

When you drop a FLAC file, your browser's native FLAC decoder (part of the Web Audio API) unpacks it back to raw PCM audio — the exact samples the FLAC originally compressed losslessly. That raw audio is then fed to the LAME MP3 encoder, compiled to JavaScript and running in a background worker, which encodes it at the constant bitrate you selected.

Before encoding, the tool reads every Vorbis comment tag — title, artist, album, track number, year, genre, composer — and any embedded cover art from the FLAC, and writes them into the MP3 as ID3v2.3 tags. The finished file is assembled in memory and handed back to you as a download. At no point does audio, metadata, or any part of your file leave your device.

This is the same LAME encoder used by fre:ac, foobar2000, VLC, ffmpeg, and dBpoweramp. Same encoder, same bitrate, same output — the software comparison covers this in detail. The difference is delivery: desktop tools need installing and configuring, while this converter is a browser tab you can close when you're done.

Convert FLAC to MP3 — FAQ

How do I convert FLAC to MP3?

Drop your .flac files onto the converter above, pick a bitrate (320 kbps is the default), and download the finished MP3s. The entire conversion runs in your browser — no software to install and no account to create.

Can I convert multiple FLAC files to MP3 at once?

Yes. Drop up to 20 files in one batch. They process one after another, and a typical 4-minute track finishes in 5–15 seconds. Use the ZIP button to download every MP3 in a single archive.

Is converting FLAC to MP3 free?

Completely free — no signup, no daily limit, no paid tier, and no watermark. Because the conversion runs on your own device, there are no server costs to pass on.

Does converting FLAC to MP3 lose quality?

MP3 is a lossy format, so some audio data is discarded during encoding. At 320 kbps the discarded content sits in frequency ranges masked by louder sounds, making the difference inaudible in blind tests for most listeners. Keep your FLAC originals as the lossless archive.

Are my files uploaded to a server when I convert?

No. Decoding and encoding happen entirely on your device using the browser's built-in FLAC decoder and the LAME MP3 encoder compiled to JavaScript. No audio, filenames, or metadata leave your browser.

What bitrate should I pick when converting FLAC to MP3?

320 kbps for the best quality — about 2.4 MB per minute. 192 kbps is a good middle ground when storage matters (roughly 40% smaller). 128 kbps works for spoken word but audibly degrades music.

Do tags and album art survive the conversion?

Yes. Title, artist, album, album artist, track and disc number, year, genre, and composer are read from the FLAC's Vorbis comments and written into ID3v2.3 tags. Embedded cover art is carried across at full resolution.

Can I convert 24-bit or high-resolution FLAC files?

Yes. The MP3 format caps out at 48 kHz, so higher sample rates are resampled to 44.1 or 48 kHz. The content above 22 kHz that gets trimmed is inaudible, and 320 kbps gives the encoder enough room to handle the rest transparently.

More ways to convert

Converting a whole album or a large collection? The batch converter handles up to 40 files per run and delivers them as a single ZIP. Want the highest-fidelity result? The quality converter locks the bitrate to 256 or 320 kbps and explains what “without losing quality” actually means for a lossy format.

Prefer a desktop tool? The guide How to Convert FLAC to MP3 (4 Free Ways) walks through VLC, fre:ac, and the ffmpeg one-liner with exact settings. And if you're still deciding whether to convert at all, FLAC vs MP3 compares the formats head to head.
