What video formats are supported?
MP4, WebM, MOV, AVI, and MKV are all supported. Most modern browsers can decode these formats natively without any plugins.
What resolution will the thumbnail be?
The thumbnail is extracted at the full native resolution of your video — exactly as many pixels as the video frame itself, with no upscaling or downscaling applied.
Is my video private?
Yes — the tool uses the browser's built-in Canvas API. Your video file is never uploaded to any server; all processing stays entirely on your device.
What can I use video thumbnails for?
Common uses include creating cover images for video players, social media preview images, blog post illustrations, storyboards, and archiving memorable frames from home videos.
