How many files can I join?

There is no fixed count, but total duration is limited by the memory available to your browser and device.

Are my files uploaded?

No. Every file is decoded and merged locally.

A crossfade lowers the ending track while raising the next track during a short overlap.

Can I mix different input formats?

Yes, when your browser can decode each format. The combined output is WAV.

Does joining recompress the audio?

Inputs are decoded to PCM samples and the joined result is written as WAV without lossy output compression.

Can I trim a file before joining it?

Use Audio Cutter first, then add the exported clip to Audio Joiner.
