How to merge audio files

  2. Drag them into order and set an optional gap.
  3. Click Merge and download one file.
Is my video safe?

Yes. Your video is only used to create your result — it’s never shared and never used to train AI.

Can I mix formats, like MP3 and WAV?

Yes. Everything is matched to the first file's sample rate and channels, then saved in the format you choose.

Is there a length limit?

The merged track can be up to 45 minutes, since it's assembled in your device's memory.
