Frequently asked questions
How do I use it?
Choose your files, adjust the options and press “Merge audio”. When it finishes, download the result.
How does it work?
Runs FFmpeg inside your browser. Pressing the process button loads about 32 MB of engine files from unpkg, with jsDelivr as a fallback. The engine is reused while this page stays open; later visits may download it again depending on browser caching. These hosts receive ordinary connection information such as your IP address, not your selected file. Internet access is needed when resources are not cached. Large clips may take several minutes. Files can be in different formats; they are converted to 44.1 kHz stereo and joined end to end.
Are my files uploaded?
No. Files are processed on your device and never sent to our servers. No account is needed.
