Frequently asked questions
How do I change video speed?+
Drop your video here. Pick a speed factor and range; the clip is re-recorded at the new pace. Then download the output — all in your browser.
Is there a size or length limit?+
There's no fixed limit, but processing runs on your device, so very long or high-resolution videos use lots of memory and time. Trim first or use shorter clips for best results.
Why is the output a WebM / GIF / WAV?+
These are the formats browsers can create natively without ffmpeg. WebM video, GIF animation and WAV audio all play widely and keep the tool 100% client-side.
Is my video uploaded?+
No. Everything is processed locally using your browser — your footage is never sent to a server.
