Getting a clean thumbnail

Video platforms usually want a thumbnail at a specific pixel size, but a raw video frame rarely matches that ratio exactly. This tool solves that by scaling the current frame so it fully covers your chosen preset dimensions, then cropping the overflow evenly from the center, so faces and subjects near the middle of the frame stay in frame. If you just want the native frame with no cropping, pick Original resolution.

Video Thumbnail Grabber FAQ

Is my video uploaded anywhere?

No. The file stays on your device and every thumbnail is drawn to a local canvas element. Nothing is sent to a server.

How does the preset size cropping work?

The frame is scaled to cover the target width and height, then centered and cropped to fill it exactly, similar to how video platforms generate thumbnails.

What does "Suggest 3 thumbnails" do?

It automatically captures frames at 25%, 50% and 75% of the video's duration so you can quickly compare a few candidates.

Can I choose the original resolution instead?

Yes, select "Original resolution" from the size dropdown to grab the frame at the video's native size with no cropping.
