Frequently asked questions
Where do my files get uploaded?
Nowhere. All processing happens locally in your browser using FFmpeg.wasm — files never leave your computer.
What file size is supported?
The limit depends on your browser's available memory. Files up to 1–2 GB usually work comfortably.
Is it free to use?
Yes, completely free and no sign-up needed. The tool runs entirely in your browser: the file never goes to a server, so the server spends neither CPU nor traffic — there is nothing to charge for. No watermarks, no limits on file size or count.
