Free tool

Pull the thumbnail out of your video

Grab one frame at the moment you scrubbed to, or a whole evenly spaced set across the clip. PNG, JPEG or WebP, at full size or scaled down, zipped in one click.

Your file never leaves this tab. It is read, edited and written by your own browser, so nothing is uploaded and nothing is stored.

Why this one

What this tool gets right

One frame or ninety

Take the exact frame under the playhead, an evenly spaced set across the clip, or one every few seconds for a contact sheet.

Seeks, does not play

Each frame is decoded from the key frame just before it, so pulling stills out of an hour-long file takes seconds, not an hour.

Your edits come with it

Crop, rotation and mirror all apply to the stills, and the trim handles decide the stretch of the clip they are sampled from.

Download one or zip them all

Click a frame to save it, or take the whole set as a zip. The zip is built in the tab, like everything else here.

How it works

Three steps, about thirty seconds

01

Drop the file in

Choose a file or drag it onto the page. It opens straight away, because there is nothing to upload.

02

Set it up

Drag the handles or type exact numbers. The preview applies the same operations in the same order the encoder will.

03

Export and download

Your machine does the encoding, with a real progress bar. The file lands in your downloads folder, unmarked.

Making a thumbnail people actually click

The frame that best represents a video is rarely the first one. Openings are often a fade, a slate or an empty room, which is exactly why platform-chosen thumbnails look so lifeless. Extract an evenly spaced set first and look at them together. The frame you want usually has a face turned toward the camera, one clear subject, and enough contrast to read at the size of a phone thumbnail. Take that one at full size, then crop it to the shape the platform wants.

Contact sheets, storyboards and QA

A set of stills at a fixed interval is a fast way to see a whole clip at a glance: where a shot changes, where the lighting drifts, whether a rendered export has a corrupt stretch in the middle. It is the same trick editors have used since film, and it is quicker to scan than scrubbing. Use the interval mode for that, keep the width small so the set stays light, and take the zip. Nothing here is uploaded, so it is also safe to do on footage you are not allowed to send anywhere.

What this tool will not do

  • It will not fetch a video from YouTube, TikTok, Instagram or any other platform. You have to have the file.
  • It will not repair a corrupt or partially downloaded file. If a player cannot open it, neither can this.
  • It will not add anything to the picture: no captions, no logos, no filters. It edits the file you brought.
  • Speed is your hardware. A long 4K clip on a phone will take minutes where a laptop takes seconds.

Questions, answered

JPEG for a video thumbnail: it is small, and every upload form on earth takes it. WebP when you control the page it will sit on, since it is meaningfully smaller at the same quality. PNG only when you need the pixels exactly as they were decoded, for example to compare two frames or to work on a still in an editor.
Yes. Scrub the timeline to the moment you want, switch the selection to 'This frame' and extract. The still is decoded at that timestamp rather than approximated from a nearby key frame.
Two reasons, both small. A player may be showing the frame nearest to your seek rather than the one at it, and a lossy format re-compresses the picture on the way out. Pick PNG and the still is exactly what the decoder produced.
Up to 400 in a single run, which is a deliberate ceiling. An interval of a tenth of a second across an hour would be thirty-six thousand images and a frozen tab, so the count is capped rather than left to trip over.
No. The file is opened by your browser with the File API and rewritten with WebCodecs, the same video machinery your browser uses to play a video. Nothing is sent to a server, so there is no upload wait, no queue and no copy of your file sitting in someone's storage bucket.
There is no limit we impose. The practical ceiling is your machine: the file is read in small pieces rather than loaded whole, so multi-gigabyte sources open instantly, and if you turn on 'write straight to disk' the result never has to fit in memory either. On a phone, expect long clips to be slow.
None of the three. Because the work happens on your machine, this costs us nothing to run, so there is nothing to gate. You get the file you made, unmarked.
Anything current: Chrome, Edge, Safari 17 and up, and Firefox 130 and up. The tools use WebCodecs, so a very old browser will report that it cannot encode, rather than producing a broken file.
