What people use it for

A good still from your video is useful far beyond YouTube.

YouTube custom thumbnails

Pull a sharp frame from your own footage as the base for a custom thumbnail, then add text and graphics in your editor.

Blog & article covers

Use a frame from an embedded video as the post's cover image, so the preview matches what readers will watch.

Social link previews

Create a preview image for a video you're sharing so the link card shows the best moment instead of a black frame.

Video poster frames

Set a still as the poster image for a video on your website — it shows before playback starts and while it loads.

Docs & bug reports

Capture an exact frame from a screen recording to point at a UI issue or illustrate a step in a guide.

Reference stills

Save frames for storyboards, mood boards, colour references, or just to keep a favourite moment as a photo.

How to pick a great thumbnail

The difference between a forgettable frame and a clickable one is usually a few frames either way.

1

Pause between movements

Frames in the middle of fast motion are blurred. Nudge the slider a little either side of the action to find a frame where the subject is still.

2

Look for faces and expression

Thumbnails with a clear, expressive face tend to draw more attention than wide shots. Scrub for the moment the reaction peaks.

3

Leave room for text

If you'll add a title on top, pick a frame with empty space on one side rather than a busy, centred composition.

4

Check it at small size

Thumbnails are usually seen tiny in a feed. Zoom out on the saved image — if the subject is still obvious, it's a good pick.

Common thumbnail sizes

Grab your frame at full resolution, then crop or resize it for where it's going.

Frequently Asked Questions

Drag the slider under the video preview to any point in the clip — the frame shown updates live. Whatever's on screen when you click download is what you get.

A JPEG, sized to your video's original resolution.

No — since the video is never uploaded to a server, this works the same for a small clip or a multi-gigabyte file. That's different from compression, which does have size tiers.

No, this runs entirely in your browser using your device's own processing power. Nothing is sent anywhere.

Any format your browser can play — MP4 and WebM work everywhere, and MOV works in most browsers. If an AVI or MKV file won't preview, compress it to MP4 first with the video compressor, then grab the frame from that.

The frame itself is blurred — usually from fast motion or the camera moving. Try a frame a fraction of a second earlier or later where the subject is still. The image is always saved at the video's full resolution.

Yes. A 1080p or 4K video gives you a frame larger than YouTube's recommended 1280×720, so it stays sharp after you add text in an editor. Keep the final file under YouTube's size limit when you export it.

Yes — scrub to a different frame and download again, as many times as you like, without re-uploading anything.
