Supported formats and limitations

Your video never leaves your device. Processing runs in your browser with FFmpeg.wasm; there is no upload, no account and no server copy.
The video engine (about 32 MB) is downloaded only after you choose a file and press Process — never automatically when the page loads.
There is no artificial usage limit and no account. Real speed and maximum size depend on your device and browser: large or long videos are slower and may run out of browser memory. A warning is shown for very large files, but no file is hard-blocked for size alone.
The thumbnail is one still frame. It has no audio and no animation.
JPG is smaller and suits photos; PNG is larger but keeps sharp text and graphics cleaner.
No artificial usage limit: capacity depends on your device and browser. Large or long videos are slower and may run out of browser memory.

Frequently asked questions

What time should I pick?

Pick a moment with a clear subject and good light, usually a few seconds in rather than the very first frame, which is often black or blurred.

Can I edit the thumbnail after?

Yes. Open the downloaded image in any image editor to add text or crop it.
