How to make a video cover from a single frame
Scrub to the right moment or enter a timestamp, then export JPEG/PNG — with tips on size and format.
A cover is just one still. Upload the video, move to the frame you want, and capture.
The first frame is often black; starting near 10% into the clip is usually safer.
Use a smaller max edge for social thumbnails; keep original size for later cropping.
Everything runs locally so your footage never leaves the device.
