How it works
- Drop your audio filesTwo or more: MP3, M4A, WAV, FLAC, OGG and more.
- Put them in orderMove them up or down and pick the MP3 quality.
- Join and downloadOne MP3 with every part, one after another.
Any mix of formats
Each file can be a different format (MP3, M4A, WAV, FLAC, OGG or the sound of a video) at any quality. They are joined one after another, with no gap added, and saved as one MP3 at the quality you pick.
Joining voice notes
Long WhatsApp or Telegram voice messages often arrive as several notes. Save them, drop them here in order, and you get one file you can listen to, send on, or turn into text.

Why your audio never leaves your computer
Online converters upload your file to their servers, convert it there and send it back. That is slow for long recordings, so free plans cap the length or the number of files, and your recording sits on someone else's computer.
Here your own computer does the work, inside this tab. Nothing is uploaded, so there is nothing to cap: no length limit, no daily limit and no sign-up.
Questions
Is there a gap between the parts?
No. Each part starts right after the previous one ends.
How many files can I join?
As many as you like, as long as the joined MP3 stays under about 1 GB, which is many hours.
Is my audio uploaded?
No. The files are joined inside your browser and saved straight back to your computer.
Is it really free?
Yes. Your computer does the work, so a file costs us nothing to convert. No account and no limits.
Is my file uploaded?
No. It is converted inside this browser tab and saved straight back to your computer.
Which browsers work?
Recent Chrome, Edge and Safari on a computer.
Can I use a video file?
Yes. Drop a video and you get its sound.
