Should you convert FLAC to MP3?
Do this to make a lossless recording small enough to share or carry around. Keep the FLAC as the master copy.
FLAC is lossless and MP3 is not
This is the conversion lossy formats were designed for: from 5 to 7 MB per minute to 1 to 2.4 MB. At 192 kbps or more almost nobody can hear the difference in music. Keep the FLAC as your master if you might need to convert again.
Where the MP3 will play
MP3 plays on everything, including car stereos and hardware twenty years old.

What usually goes wrong
About the FLAC. Converting an MP3 to FLAC produces a large file that sounds exactly like the MP3. Lossless compression preserves what it is given, including the damage.
About the MP3. Converting an MP3 to another lossy format compounds the damage, because the second encoder is guessing at audio the first one already threw away.
How to convert FLAC to MP3

Questions
How do I convert FLAC to MP3?
Open this page, add your FLAC file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this FLAC to MP3 converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to MP3 lose quality?
MP3 is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several FLAC files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
