Extract a frame from a video
A player with a filmstrip rather than a form. Tap a tile to jump, drag the scrubber to get close, then step one frame at a time until you are on the right one. What you save is the video's own pixels at its full width and height, not a screenshot of a player with its controls in the way.

How to use it
- 1
Open a video
Drop a file on the panel or tap to choose one. MP4 with H.264 and WebM open in every browser, and nothing is uploaded.
- 2
Jump with the filmstrip
Twelve tiles spread evenly across the clip show you roughly where each shot sits. Tap one and the player goes there.
- 3
Land on the frame
Drag the scrubber to get close, then use the frame buttons to step one frame back or forward. The readout gives the time, the frame number and the pixel size.
- 4
Save it
One button writes the current frame at the video's own resolution. Advanced options adds the format and a way to save a whole run of frames.
A frame is not a screenshot
Screenshotting a paused video gives you whatever the player was showing: scaled to the window, often with a control bar across the bottom and a play button in the middle. This draws the video element onto a canvas sized to its own videoWidth and videoHeight, so a 4K clip yields a 4K image even in a small browser window, with nothing on top of it. The message after saving names the pixel size it actually wrote.
Why the filmstrip is the timeline
A bare slider tells you nothing about what is at a given position, so finding a shot means dragging blind and waiting for each seek. Twelve thumbnails across the clip turn that into looking. A separate detached copy of the video does the seeking that fills them, so the strip can populate without disturbing the player you are scrubbing, and the tile you are currently on is named as well as outlined.
Which files will open, and why
Browsers only decode the codecs they ship. H.264 in MP4 and VP8 or VP9 in WebM work everywhere. AV1 is close but still patchy on older Apple hardware. HEVC depends on the operating system, and ProRes, DNxHD and most AVI files were never web formats at all. If a file refuses to open, the fix is to save it again as MP4 with H.264 in any editor, which every browser will then read.
Limits
- The browser has to be able to decode the file. MOV, AVI and many HEVC clips will not open.
- The frame rate is measured from the clip and snapped to the nearest common rate. Set it yourself if the guess is wrong.
- A run saves at most sixty frames, and they arrive as separate downloads.
- Stepping a frame seeks by time, so a variable frame rate clip can land either side of the one you wanted.
What it does not do
- It does not trim, cut or re-encode the video.
- It does not crop the frame. Save it, then crop it in the image cropper.
- It does not pull out audio or subtitles.
Questions people ask
Is the video uploaded?
No. The file is opened straight from disk into the page and read there, so nothing leaves your machine. That matters for footage that is not public yet, or for anything with a person in it who has not agreed to be on somebody else's server. Closing the tab discards it.
My file will not open. Why not?
The browser has to decode it, and not every format qualifies. MP4 with H.264 and WebM work everywhere. MOV, AVI, ProRes and many HEVC clips do not, because those codecs are not ones browsers carry. Saving the file again as MP4 with H.264 in any editor will fix it.
Is the saved image really full resolution?
Yes. The frame is drawn onto a canvas set to the video's own width and height, not to the size it happens to be displayed at in the page. A 4K clip gives a 4K image even in a small window, and the message after saving tells you the pixel size it wrote.
How accurate is stepping by one frame?
The rate is measured from the clip itself, by reading the presentation time of successive frames and snapping to the nearest common rate. A step then moves by exactly one of those, which is right for constant rate footage. Variable rate clips can land either side, so set the rate yourself in Advanced options.
What is the filmstrip for?
It is the coarse timeline. Twelve tiles spread evenly across the clip let you see roughly where a shot changes instead of dragging blind. Tap one to jump there, then use the scrubber and the frame buttons for the exact moment. The tile you are sitting on is labelled, not just outlined.
Can I save more than one frame?
Yes. Under Advanced options, mark a start and an end with the two buttons, choose how many frames to skip between saves, and it walks the range for you. Up to sixty frames arrive as separate downloads, named with the frame number so they sort into order on disk.
PNG, JPEG or WebP?
PNG keeps every pixel and suits a frame you will edit, crop or key. JPEG is much smaller and fine for a thumbnail or a rough reference. WebP sits between them, close to JPEG in size but noticeably cleaner on flat colour and text. The choice sits under Advanced options.
