Grab a single frame from a video as an image

A thumbnail for a listing, a still for a slide, proof of a moment — the frame comes straight off the local file at native resolution.

The job

Video sites pick their own thumbnails and phones bury frame export behind editors. When you need one specific frame as a picture — for a blog cover, a bug report, an archive — capturing the decoded frame directly is the lossless route.

How to do it

Choose the video, then either type the time (5.5 seconds or 0:05) or scrub the player to the right moment, and capture. The PNG is the frame as decoded — the video's own resolution, no upscaling.

Pause a fraction before the moment and step with the typed seek for the sharpest pick.
For an action frame, ±0.1 s makes a visible difference in motion blur.

Worked example

Capturing the title card of a screen recording produces a clean PNG for a bug report at 1920×1080 — the same pixels the player decoded, not a screenshot with OS chrome and scaling artifacts.

Limits

The browser has to be able to play the file — mp4 and webm are safe, mov depends on the platform. A heavily compressed video yields a compressed-looking frame; the PNG is honest, not enhanced. Files are read locally up to 2 GB.
