Frequently asked questions
Are my files uploaded to a server?
No. Every conversion runs inside your browser tab using the Canvas, Web Audio and MediaRecorder APIs that are built into the browser itself. Your file is read into memory, converted, and offered back to you as a download. It is never transmitted anywhere, and nothing is written to disk or to any storage service.
Do I need an account?
No. There is no sign-up, no email address and no login. Open the page, drop a file, download the result.
Is there a file size limit?
There is no artificial limit. The practical ceiling is your device's available memory, because the whole file is held in RAM while it converts. Very large video files are the most demanding.
