Snapmark - Screenshot & Annotate

Capture the visible area, a selection, a full page or any window, then annotate with arrows, highlights, text, blur and more.

Snapmark captures anything on your screen and lets you mark it up in seconds. Everything happens on your computer: no account, no uploads, no tracking. CAPTURE • Visible area – the part of the page you're looking at • Selected region – drag a box around exactly what you want • Full page – scrolls and stitches long pages into one image, including pages with their own inner scrollbar • Any window or your whole screen – pick from Chrome's own picker Start from the toolbar button, a keyboard shortcut or the right-click menu: • Alt+Shift+V – visible area • Alt+Shift+S – selected region • Alt+Shift+F – full page • Alt+Shift+D – window or desktop ANNOTATE • Tapered arrows that grow with their length, and curved arrows with a draggable bend • Lines, rectangles (optionally rounded) and ellipses • Pen and highlighter • Text labels and speech-bubble callouts • Numbered step badges for tutorials and bug reports • Blur or pixelate to hide passwords, emails and other private details • Spotlight to dim everything except the area that matters • Emoji stamps • Crop Every annotation stays a separate object, so you can select it, move it, resize it, change its colour, size or opacity, duplicate it or delete it at any time. Full undo and redo, zoom and pan. SAVE AND SHARE • Download as PNG or JPG, with a quality slider for JPG • Copy to the clipboard and paste straight into email, chat or a document • Local history: your captures are saved in your browser with their annotations, so you can reopen and keep editing later. You choose how many to keep, and you can delete them whenever you like. PRIVATE BY DESIGN Snapmark works entirely offline. Screenshots never leave your device, and there are no servers, analytics or ads. It only touches a page when you start a capture, using Chrome's "active tab" permission. It has no standing access to any website. The source code is open and MIT licensed: https://github.com/jay2u/snapmark GOOD TO KNOW • Chrome doesn't let extensions read its own pages (chrome://, the New Tab page), the Chrome Web Store or PDF viewer. On those pages, full-page capture falls back to the visible area. Window and desktop capture still works. • To capture local files, turn on "Allow access to file URLs" in the extension's details. • Very tall pages are capped at 30,000 pixels of page height.
