How the Video Thumbnail Generator works
This tool loads your video into a hidden HTML5 <video> element entirely in your browser — nothing is uploaded to a server. Dragging the timeline slider seeks the video to that exact timestamp; once the browser reports the frame is ready (the seeked event), the current frame is drawn onto a <canvas> using drawImage. Clicking "Capture frame" exports that canvas as a PNG (lossless, larger file) or JPG (adjustable quality, smaller file) using canvas.toBlob, ready to download.
This is useful for picking a custom thumbnail for a video upload, grabbing a preview image for a blog post or social share, or extracting a single still from a screen recording. Supported video formats depend on your browser's built-in decoders — MP4 (H.264) and WebM work in virtually every modern browser.
Private & free — this tool runs entirely in your browser.
