Video Thumbnail Generator — Extract Still Frames from Video
A compelling thumbnail is one of the most important factors in whether a viewer clicks on a video. This browser-based video thumbnail generator lets you extract any frame from a video file as a high-quality JPEG or PNG image, giving you precise control over the exact moment you want to capture without any software installation or server uploads.
The tool supports custom timestamp input — type a time in seconds or HH:MM:SS format to jump to any specific frame. Alternatively, use the automatic center-frame option, which calculates the midpoint of the video and extracts a frame from there, providing a statistically likely representative image for use as a preview or poster frame.
Thumbnails generated by this tool are suitable for YouTube video covers, Open Graph `og:image` meta tags, video embeds on websites, and social media previews. JPEG output provides smaller files ideal for web use. PNG output delivers lossless quality suitable for further editing or professional print use. All frame extraction is handled by FFmpeg-WASM locally — your video file is never uploaded, making this tool safe for private recordings.
