It's perfect for creating video thumbnails for YouTube, blog post featured images, social media previews, or any situation where you need a still image from a video.

Technical Guide
The Video Thumbnail Extractor uses an HTML5 Video element for playback with a timeline slider for seeking. When the user clicks capture, the current video frame is drawn onto a Canvas element at the video's native resolution using drawImage(). The canvas content is then exported as an image using toBlob() with the selected format (image/png for lossless, image/jpeg with configurable quality). For PNG output, the full pixel data is preserved. For JPEG, the quality parameter (0.0-1.0) controls compression. The tool listens for the video's seeked event to ensure the frame is fully rendered before capture. Multiple frames can be captured from different time points without re-uploading the video.
