How to use the video thumbnail generator

  1. Choose a video (MP4, WebM, MOV).
  2. Pick a grid size and click Create contact sheet — frames are taken evenly across the whole video, with timestamps.
  3. Or drag the slider to any moment and click Save current frame for a full-size thumbnail.

A contact sheet shows the whole video at a glance — handy for choosing a YouTube thumbnail, checking a long recording, sharing a preview with a client or archiving home videos. Frames are captured by your browser’s own video player, so nothing is uploaded and the original file is untouched.
