Join FLAC tracks into one gapless, lossless file - a whole album, a concert or a vinyl side. Need it smaller for the car? Convert the result with FLAC to MP3.

Paste them into a YouTube description or podcast show notes - YouTube turns them into chapters.
Want a cue sheet? After merging, Track start times gives you the exact start of every track - perfect for writing one.
FLAC is lossless, so merging FLAC to FLAC keeps every sample - as long as you join back to back and leave the volume alone.
24-bit tracks are written as a 24-bit FLAC. Tracks with different sample rates have to be converted to one rate, because a file can only have one; for a normal album they all match and nothing is resampled.
Live albums, classical works and DJ sets play straight through, exactly like the original disc.
Browsers can read FLAC but cannot write it, so FLAC output is merged on our server with FFmpeg.
Your tracks travel over HTTPS and are deleted right after merging, and the merged FLAC once you download it. Rather keep everything on your device? Pick WAV - it is just as lossless and merges entirely in your browser (see Merge WAV).
| Album | FLAC | WAV | MP3 320 |
|---|---|---|---|
| 45 min, 16-bit / 44.1 kHz | about 270 MB | 455 MB | 105 MB |
| 45 min, 24-bit / 96 kHz | about 1.1 GB | 1.5 GB | 105 MB |
Our server takes up to 300 MB of FLAC per merge - a normal CD album fits. For hi-res albums, merge in two halves or save as WAV in your browser.
Drop the FLAC tracks into the box, press A-Z to sort them and press Merge. One FLAC file downloads when our server is done.
No. FLAC to FLAC with back to back joins is bit-perfect, and 24-bit tracks stay 24-bit. Only effects you switch on (loudness, fades, crossfades) change the audio.
Yes - keep Back to back. The tracks join with no pause and no click, just like a gapless CD.
Yes. After merging, Track start times lists where every track begins in the merged file. Copy them into your cue sheet or show notes.
For FLAC output, yes - browsers cannot write FLAC. Your tracks are deleted right after merging. WAV output merges entirely in your browser.
Up to 20 tracks and 300 MB in total for FLAC output. Save as WAV to merge up to 50 tracks in your browser.
Yes - free, no account and no watermark.
