Capture screenshots of visible tab content or selected areas with annotation tools and instant download.
Screenshots are something every operating system already does, but the result usually lands in a file that still needs cropping, markup, and another app to edit. This tool keeps the entire loop in the tab: capture what is currently visible, or drag a box around a selected area, mark it up, and download a finished image - all without leaving the page. Everything runs in the browser, so a capture never gets uploaded anywhere. What surprises most people: the image records only what is on screen at the moment of capture, never the content you scrolled past.
The toolbar offers two capture modes. Whole-tab capture takes exactly what is currently visible in the page area, leaving out the browser's own chrome such as tabs and the address bar. Area capture dims the page and lets you drag a rectangle, and only the pixels inside it appear in the result. Both modes sample the page as it renders at that instant.
Captured images open in an editing view with a small drawing set: arrows, boxes, highlights, and text labels, plus undo and redo for correcting mistakes. Marks can be moved or deleted while you edit. Downloading produces a single image file with every mark drawn into it - a flat picture, not a layered project you can reopen and re-edit.
No. Capture, annotation, and download all run locally in the browser, and the image never leaves your device. That matters if the screen contains personal or confidential data. The only way the picture reaches anyone is if you send the downloaded file yourself.
The tool captures the tab's page area, not the whole screen, so the browser's tabs, address bar, and any other windows are absent. If you need surrounding chrome or multiple windows in one image, use your operating system's own screenshot shortcut instead.
