Grab frames from a video

Scrub to the moment you want, step frame by frame, and save it at full resolution. Or let the tool suggest six sharp frames for a thumbnail.

Your file never leaves this device. Everything runs in your browser.

How it works

  1. Drop your video.
  2. Scrub to a moment and use the arrows to step one frame at a time, or press Suggest thumbnails.
  3. Grab the frames you like and save them as PNG or JPG.

Questions

What resolution are the images?

The video's own full resolution, the right way up.

How are thumbnails suggested?

The tool looks at 32 frames across the video, skips black, white and blurry ones and near-duplicates, and shows the six sharpest.

PNG or JPG?

PNG keeps every pixel exactly. JPG is much smaller and fine for a thumbnail. YouTube takes either, under 2 MB for most uploads.

Does my video get uploaded?

No. Frames are read in your browser, on your device.
