Capture and Annotate a Screenshot Online
This snipping tool runs in your browser and captures whatever you pick from your browser’s own screen share prompt: the entire screen, one window, or a single browser tab. There is nothing to install and no account needed to take the capture.
Once you have the image, you can draw on it directly in the browser: a pen, a highlighter, arrows, rectangles, circles, and text labels, each in a color you choose. Undo a mark, reset the whole thing, and start again as often as you like.
What you get:
- A capture of your screen, a window, or a browser tab, at your screen’s own resolution
- Drawing tools: pen, highlighter, arrow, rectangle, circle, and text
- Download as a PNG, or copy the finished image straight to your clipboard
- Save it to your ScreenApp account to open it again on another device
The tool captures a single frame of what you select. It does not stitch a scrolling page into one long image, and it does not let you draw a custom selection box before capturing, since the browser’s own screen share picker chooses the source. If you need a scrolling capture of a webpage, a browser extension built for that job is a better fit.
How to Snip and Annotate a Screenshot
- Click “Capture Screen” and pick your screen, a window, or a browser tab in the prompt your browser shows.
- Mark it up with the pen, highlighter, arrow, rectangle, circle, or text tool, and undo any mark you don’t want.
- Download, copy, or save it. Download the PNG, copy it to your clipboard, or save it to your ScreenApp account to reach it from another device later.
Sharing the screen you meant to share is the one thing worth checking before you capture: pick the specific window or tab rather than your whole screen if you don’t want other open windows in the shot. See how ScreenApp handles your data.

- vs Windows Snipping Tool: Windows’ own tool is free and built in, with rectangle, freeform, window, and full-screen capture, but it only works on Windows and saves to your local drive. ScreenApp runs in any browser and saves a copy to your account so you can open it from another device.
- vs ScreenClip: ScreenClip’s free plan is capped at 100 files and 1 MB per file, and it also does scrolling captures, which ScreenApp does not. ScreenApp has no file-count cap on the captures you download or copy yourself.
- vs Supademo: Supademo’s snipping tool is free on its own, but the wider Supademo product it feeds into starts at $38 a month per seat, billed annually, once you want the interactive-demo features. ScreenApp keeps annotation and cloud saving on the free plan.
Who Uses the Online Snipping Tool
Customer support teams capture an error message or a settings screen and mark it up with an arrow before sending it to a customer, without opening a separate app.
Software developers grab a window showing a bug and circle the part that’s wrong, then drop the image straight into a ticket.
Educators capture a slide or a diagram, label the parts with text and arrows, and use it in a handout or a lesson.
Content creators save reference images from a browser tab while they’re researching, and mark up the section they want to reuse.
Remote teams capture a shared screen during a call and annotate it afterward to point out exactly what needs to change.
