FLAC to MP3 Converter – Free Online

How to Convert FLAC to MP3 Online

Upload your FLAC file

Drag and drop your .flac file onto the page or click to browse. You can select several FLAC files at once to batch-convert them.

MP3 is preselected

The output format is already set to MP3, so you can convert immediately. If you need to, adjust the audio codec, bitrate or sample rate in the settings panel first.

Convert and download

Click Convert. The MP3 file is processed on your own device; nothing is uploaded to a server. When it finishes, click Download to save it (or Download all to get a batch as a ZIP).

Why Convert FLAC to MP3?

FLAC keeps every bit but many phones, cars and portable players cannot play it, and the files are five to six times larger than MP3. Converting FLAC to MP3 at 320 kbps gives you near-transparent quality in a file that plays on absolutely everything.

The converter decodes the FLAC in your browser, preserves album, artist and title tags, and encodes at the bitrate you choose. Batch-convert an entire album by dropping all the tracks at once.

Private by design: your FLAC file is converted on your own device and never uploaded.
MP3 preselected: the output format is already chosen, so it is a one-click conversion.
Batch friendly: convert several FLAC files in one go and download them as a ZIP.
No limits, no watermark: free for files of any size, with nothing stamped on the output.

FLAC vs MP3

FLAC (Free Lossless Audio Codec): FLAC (Free Lossless Audio Codec) compresses audio to roughly half the size of WAV without discarding a single bit, so it decodes back to the identical original. It is best for lossless music libraries and audiophile listening.

MP3 (MPEG-1 Audio Layer III): MP3 is the universal lossy audio format. It plays on every device made in the last twenty-five years and offers small files with good quality at 192 to 320 kbps. It is best for music players, podcasts, phones and sharing.

In short: keep FLAC when the priority is lossless music libraries and audiophile listening, and switch to MP3 when the file is headed for music players, podcasts, phones and sharing. Need a different target? The full Audio Converter supports every format listed below.

FLAC to MP3 FAQ

Will I hear the difference between FLAC and 320 kbps MP3?

In blind tests almost nobody can distinguish them on normal equipment. Keep the FLAC as your archive and use MP3 for portable devices.

Are the tags kept?

Yes. Title, artist, album, genre and year are copied into the MP3's ID3 tags and can be edited before converting.

Is this FLAC to MP3 converter free?

Yes. Converting FLAC to MP3 on MediaConverter.io is completely free, with no watermark, no sign-up and no daily conversion limit.

Are my FLAC files uploaded to a server?

No. The converter runs inside your browser using WebAssembly and WebCodecs, so your .flac file is read and converted on your own device. Nothing is uploaded, which keeps private recordings private and means there is no waiting in an upload queue.

Is there a file size limit for FLAC to MP3?

No fixed limit. Because processing happens locally, the practical limit is your computer's memory and patience; multi-gigabyte FLAC files convert fine on a desktop browser. Very large files take longer on phones.

Will converting FLAC to MP3 reduce quality?

MP3 is a lossy format, so the FLAC audio is decoded and re-encoded. Keep the bitrate at 100% (or pick 256 to 320 kbps) and the difference is inaudible for almost all listeners.

Which browsers support the FLAC to MP3 converter?

Current versions of Chrome, Edge, Firefox and Safari on desktop all work. Chrome and Edge are fastest because they expose hardware-accelerated WebCodecs decoders.
