Load your video, scrub to the frame you want, and press Capture. Download the still image as a JPG or PNG.
Scrub the video to the exact moment you want using the timeline, then capture — the tool grabs the frame currently showing in the preview.
JPG gives a smaller file and is fine for most thumbnails; PNG is lossless and better if the frame contains sharp text or graphics you want to keep crisp.
No, this tool reads the frame directly from the video element and a canvas, so it works instantly without downloading the larger video-processing engine.
