Convert FLAC to MP3 Online

Upload a FLAC file and convert it to MP3 for easy sharing and playback on any device. Fast, free, browser-based conversion.

How it works

  1. Upload your FLAC file. Drag your FLAC audio into DomeScribe. Files at any sample rate — including hi-res 96 kHz and 192 kHz — are fully supported.
  2. Check lossless audio details. DomeScribe reads the FLAC metadata and shows bit depth, sample rate, channel layout, and embedded album art so you can verify the source before converting.
  3. Pick your target MP3 bitrate. Select a bitrate that balances quality and file size. At 320 kbps the difference from the FLAC source is nearly imperceptible to most listeners, while 192 kbps offers a good middle ground.
  4. Convert and download the MP3. Click Convert to transcode your lossless FLAC into a portable MP3. The output retains ID3 tags and album art, ready for any MP3 player or smartphone.

Frequently asked questions

Why convert FLAC to MP3 instead of keeping the lossless file?

FLAC files are significantly larger and not universally supported — many car stereos, basic MP3 players, and some streaming apps cannot play them. Converting to MP3 with DomeScribe makes your music portable and compatible with virtually every audio device in existence.

At what MP3 bitrate will I stop noticing the difference from FLAC?

Most listeners cannot distinguish FLAC from 256 kbps or 320 kbps MP3 in blind tests. If storage is not a concern, 320 kbps — DomeScribe's highest MP3 setting — is the safe choice. For large libraries where space matters, 192 kbps offers a good balance of quality and efficiency.

Does DomeScribe preserve album art and tags when converting FLAC to MP3?

Yes. DomeScribe reads Vorbis comments and embedded cover art from the FLAC file and writes them into the MP3's ID3v2 tags. Artist, album, track number, genre, and cover images all transfer automatically.

Can I batch-convert my entire FLAC music library?

DomeScribe processes one file at a time through the web interface, but each conversion is fast — typically just a few seconds per track. You can upload and convert files in rapid succession to work through a library efficiently.

Will converting hi-res FLAC (96 kHz / 24-bit) to MP3 cause problems?

Not at all. DomeScribe automatically handles the resampling from high sample rates down to 44.1 kHz or 48 kHz, which is standard for MP3. The encoder applies proper dithering and anti-aliasing filters to ensure a clean, artifact-free result.
