Drop in your FLAC files and get MP3 files back. Everything runs in your browser: nothing is uploaded, there is no file size limit and you do not need an account.
Accepts: images (PNG, JPG, WebP, GIF, BMP, SVG, ICO, AVIF, HEIC), PDF, Word (.docx), Markdown, HTML, TXT,
spreadsheets (XLSX, XLS, ODS, CSV, TSV), JSON, XML, YAML, and video (MP4, MOV, WebM, MKV) or audio. Video can become GIF (first 15 seconds), WebM or MP4 (recorded in real time, so it takes as long as the video), a still image, or just the audio. Mixed batches are fine.

How to convert FLAC to MP3
Drag your FLAC files into the box above, or click it to choose them.
MP3 is already selected as the output format.
Press Convert Files, then Download All. Several results arrive as one ZIP.
Why convert FLAC to MP3?
MP3 is much smaller than FLAC, so more music fits on a phone, player or USB stick.
FLAC is lossless compressed audio. MP3 is the universal audio format, supported by practically every player.
Your files never leave your device
Most online converters upload your files to a server. This one does the work inside your browser, so your FLAC files stay on your computer or phone. That also means no waiting for uploads and no cap on file size.
Good to know
Your browser has to be able to decode the source file; current browsers handle MP3, WAV, M4A, OGG and FLAC. MP3 output is 128 kbps.
Frequently asked questions
Are my FLAC files uploaded to a server?
No. The conversion runs inside your browser on your own device. Your files are not sent to us or anyone else. Besides loading this page and, for some formats, a small helper library, nothing is downloaded or uploaded while you convert, and you can confirm that in your browser's developer tools (Network tab).
Is there a limit on file size or number of files?
We do not set one. The only limit is your device's memory, so for very large batches (thousands of files, or very big videos) work in several groups.
Do I need to sign up, install anything or accept a watermark?
No. There is no account, no install and no watermark. Open the page, add your files and download the results.
How do I convert many FLAC files at once?
Drag them all in together or pick them in the file chooser. They are converted one after another, and Download All saves the results as one ZIP (a single result downloads directly).
Are there any limitations converting FLAC to MP3?
Your browser has to be able to decode the source file; current browsers handle MP3, WAV, M4A, OGG and FLAC. MP3 output is 128 kbps.
