Private by design

Most online screenshot tools upload your image to their servers to process it. Shotmark doesn't — every pixel is handled locally in your browser, so a screenshot of your dashboard, your inbox or your bank stays yours. There's no account, no tracking of your images, and nothing to leak.

Capture without leaving the page

The Chrome & Edge extension grabs the visible area or a full, scrolling page — then lets you copy it, edit it, or save a PNG in one click. Annotation, redaction and OCR all run right inside it, still 100% on your device.

Coming soon to the Chrome Web Store & Edge Add-ons. Use the web app today.
