Why Convert FLAC to MP3?

FLAC files preserve studio-quality lossless audio, but their large file sizes make them impractical for streaming, portable devices, and sharing.

Converting to 320 kbps MP3 gives near-transparent audio quality at roughly one-tenth the file size, making lossless recordings practical for everyday listening.

Frequently Asked Questions

What bitrate should I use when converting FLAC to MP3?
320 kbps is the recommended setting for converting from lossless FLAC. This maximizes MP3 quality and is indistinguishable from the source in double-blind listening tests for most content.
Will I be able to tell the difference between the FLAC and the MP3?
At 320 kbps, most people cannot distinguish FLAC from MP3 in controlled double-blind tests. The difference is most audible on critical listening headphones with complex orchestral music.
Should I keep the original FLAC after converting?
Yes. FLAC is your lossless master. Keep it archived and use the MP3 for daily listening. Storage is cheap; re-encoding from MP3 permanently reduces quality.
Does the converter preserve FLAC metadata tags?
Yes. The converter copies standard metadata tags including artist, album, title, track number, year, and embedded album art to the output MP3.
Is this conversion really free, and is my file private?
Yes. The browser conversion runs entirely on your device using WebAssembly. Files are never uploaded to a server and are discarded from memory when you close the page. There is no file size tracking, no account link to your upload, and no cloud storage.
Do I need to create an account to convert files?
No. The browser converter works without signing in. An optional account is only needed if you want to save favorites, track conversion history, or upgrade to the desktop app with Polar license activation.
How fast is the conversion?
Most browser conversions complete in a few seconds. Large files (over 100 MB) or heavy formats (video, high-page PDFs) take longer depending on your device's CPU and available memory. The desktop app runs significantly faster using native engines.
