How do I join audio files together?
Add your audio files, put them in order and choose a format. No gap plays the tracks back to back; a 2 or 5 second crossfade blends the end of each track into the next, like a DJ mix. Files with different formats and sample rates can be mixed.
You can also add videos to use their soundtracks. Everything runs in your browser, so your files are never uploaded.

Questions
Can I merge different formats?
Yes. MP3, M4A, WAV, OGG and FLAC can be mixed in one go.
Which format should I save as?
MP3 plays everywhere. WAV keeps full quality but is about ten times larger.
Does merging lower the quality?
MP3 and M4A are saved at 192 kbps, which sounds the same as the original for most listening.
