Questions people ask
Are my files uploaded?
No. The files are joined in your browser with a WebAssembly build of ffmpeg. They stay on your device.
Can I join different formats?
Yes. For example an MP3 and a WAV can be joined. They are converted to the format you choose.
How many files can I join?
Up to 20, each up to 300 MB.
Will there be a gap or a click between tracks?
Tracks play back to back with no gap unless you set a silence. Files that start or end with their own silence keep it.
Why does it take a moment to start?
The converter is about 30 MB and downloads the first time you use an audio or video tool. After that your browser keeps it.
