Questions

Does the sound change pitch?

No. The sound is sped up or slowed down without sounding higher or lower.

What speed is best for Reels?

1.25× to 1.5× makes a slow clip feel lively without looking rushed. 0.5× is great for a slow-motion product reveal.

Is it free?

Yes, completely free with no sign-in, no watermark and no daily limit.

Is my video uploaded?

No. The tool runs inside your browser with FFmpeg, so your video never leaves your device. Nothing is stored anywhere.

Why does the first run take a little longer?

The first time, your browser downloads the video engine (about 30 MB). After that it is ready for the rest of your visit.
