Why convert FLAC to MP3?
Free Lossless Audio Codec (FLAC) preserves every harmonic detail of studio master recordings with bit-perfect fidelity, but a single lossless album can easily consume 400MB to 1GB of storage. Furthermore, Apple devices (iPhone and iPad Music apps) do not support native FLAC playback. Converting FLAC to MP3 reduces storage consumption by approximately 80% while retaining pristine acoustic fidelity for mobile listening and portable digital audio players.
Quick guide
How to convert FLAC to MP3
Load your FLAC library
Select individual FLAC songs or queue an entire album batch by dragging files into the drop area.
Select audio quality
MP3 is selected as the target. Choose constant bitrate (CBR) up to 320 kbps or variable bitrate (VBR) for maximum efficiency.
Download MP3 files
Client-side FFmpeg decodes the 24-bit/16-bit PCM stream and encodes the MP3. Grab individual files or a ZIP album.
Can humans hear the difference between FLAC and 320 kbps MP3?
In blind ABX listening tests, high-bitrate 320 kbps MP3 audio encoded with modern psychoacoustic models is virtually indistinguishable from lossless FLAC for the vast majority of listeners and playback equipment.
Are FLAC tags like artist, album, and track number retained?
Yes. Vorbis comments embedded in your FLAC files are automatically mapped and written to standard ID3v2 metadata frames in the output MP3.
Do my high-resolution audio files leave my computer?
No. High-resolution FLAC files can be large, but because processing occurs 100% locally in your browser tab, no data is uploaded to remote cloud servers.
