Generate Video Thumbnail (Free, Online, No Upload)

Generate a thumbnail image from any video right in your browser. Nothing gets uploaded to a server. Pick a specific timestamp or let the tool grab a frame automatically. The extraction runs locally using FFmpeg compiled for your browser, so your video stays on your device.
