Video thumbnail picker
Scrub the timeline, grab any frame as PNG or JPG.
About this tool
Scrub through any video, pick the exact frame you want, and save it as a PNG or JPG image. The right tool for choosing a custom YouTube thumbnail, picking a clean still for a podcast cover, or grabbing a hero image from product footage.
The captured frame uses the source video's full resolution, so the saved image is as crisp as the video itself. The whole tool runs in your browser - no upload, no quality loss from server-side re-encoding.

Frequently asked questions
Yes - the captured frame uses the source video's full pixel dimensions. A 4K video gives a 3840×2160 image.
The on-screen preview is downscaled for performance. The exported file always uses the source resolution.
JPG is fine - YouTube re-encodes thumbnails anyway, and JPG is smaller for upload.
Use the Frame Extractor tool for batch extraction at a fixed rate.
Most video formats only allow seeking to keyframes; the nearest keyframe to your requested time may be a fraction of a second away. For frame-exact capture, ask for an offset slightly past the moment you want and the encoder will land on it.
Yes by default. Use the resize option if you want a smaller thumbnail for social media or a video gallery.
