Frequently asked questions
Will the output be exactly 25MB?
The tool estimates the bitrate from the video duration and target size. Most files will be close, but one-pass browser encoding can be slightly above or below the target.
Is my file uploaded?
No. The conversion runs in your browser using WebAssembly. The file stays on your device.
Why is the first conversion slower?
The browser has to load the FFmpeg WebAssembly core the first time. After that, it is usually cached by the browser.
