Grab your screen or a window straight from the browser, draw and write on it, and save it as PNG, JPEG or WebP.
Your browser will ask which screen, window or tab to share. One frame is grabbed and the share stops immediately. Nothing is uploaded.
Asks the browser for a one-off screen share, copies a single frame from it and stops the share immediately. What you get is a full-resolution capture of the screen, window or tab you picked in the browser’s own prompt, shown on a canvas you can draw on with a pen, add text to, or erase parts of. You can also drop an existing screenshot to annotate it. The download is made from that canvas in the format you choose, and Copy puts it on the clipboard for pasting into a chat or a document.
A 2560 × 1440 capture of a dashboard saved as PNG is about 1.8 MB with perfectly crisp text; the same capture as WebP at quality 85 is around 260 KB and still readable, and as JPEG at 85 about 420 KB with faint ringing around small text. Circling a button with a 4 px red pen and adding a 32 px label takes two clicks in the panel. On a laptop the capture prompt appears within a second; on a second monitor pick that screen in the prompt.
Use it when you need a picture of what is on screen without installing anything: a bug report, a step in a how-to, a receipt from a web page, a chart from a dashboard. It captures whole screens and windows, not a hand-drawn region, so trim the result with Crop Image afterwards if only part matters, and hide anything private with Censor Photo before sharing. For arrows, boxes and callouts beyond the pen, pass the capture to Image Annotation. Screen capture needs a desktop browser such as Chrome, Edge or Firefox over HTTPS; phones do not offer it to web pages.
Entire screen and A window only choose which tab the browser prompt opens on; the final choice is made in that prompt. Draw uses the colour and line width; Erase clears what you drew, and its size is four times the line width. Text is typed in the panel first, then placed by clicking on the capture, aligned left, centre or right from that point. Clear marks returns to the untouched capture. PNG keeps screen text exact; WebP is much smaller and nearly as sharp; JPEG is for photo-like captures. The file name accepts a {date} token.
Why does the browser show a picker instead of taking the picture? Browsers require you to choose what to share every time, for privacy. Pick the screen, window or tab and click Share; the frame is grabbed right after and the share stops on its own.
Can it capture a chosen area only? Not directly; browsers only offer whole screens, windows or tabs. Capture the window, then trim with Crop Image.
Why does nothing happen on my phone? Mobile browsers do not expose screen capture to web pages. Use the phone's own screenshot shortcut and drop the image here to annotate it.
Is the capture uploaded? No. The frame stays in your browser's memory; the download and the clipboard copy are made locally.
