What video formats are supported?

The tool supports MP4, WebM, and MOV video files. These cover the vast majority of video formats used on the web and in content creation. The video is processed entirely in your browser using the HTML5 Canvas API.

How many thumbnail frames are extracted?

The tool automatically extracts 11 frames at evenly spaced intervals throughout the video (at 0%, 10%, 20%, up to 100% of the video duration). This gives you a comprehensive set of frames to choose from.

Is my video uploaded to a server?

No. All processing happens entirely in your browser using JavaScript and the Canvas API. Your video file never leaves your device, making it completely safe for sensitive or private content.

Can I add text and borders to the thumbnail?

Yes. After selecting a thumbnail frame, you can add a text overlay with customizable position, font size, and color. You can also add a border with adjustable width and color. These customizations are applied when you download the thumbnail.
