Combine multiple audio files into one, in whatever order you pick. Even if the formats or sample rates differ — MP3, M4A, WAV — they're automatically matched before stitching, and the result is saved as MP3. Reorder with the up/down buttons in the list. Everything runs inside your browser, so the files are never uploaded to a server.

- 1Select or drag in 2 or more audio files to merge (add more as needed).
- 2Use the up/down buttons in the list to set the order to stitch them in.
- 3Click Merge and download the resulting MP3.
When it comes in handy
For example, it's handy for stitching together voice memos or lecture recordings you captured in several separate takes.
Files recorded on different apps or devices, with mismatched formats or sample rates, are automatically converted to a common format before stitching, so there's no need to convert them beforehand.
What happens with mismatched formats
Stitching requires every segment to share the same audio format (sample rate and channels), so each file is automatically converted to 44.1kHz stereo before being joined. The result is always saved as MP3.
