Questions
Can I paste a screenshot?
Yes — press Ctrl+V / ⌘V anywhere on the page to load an image from your clipboard, then copy the result back with one click.
Is the pixelate tool safe for passwords?
It replaces the area with large blocks in the exported image. For truly sensitive text, a solid box is safest.
Is my screenshot uploaded?
No. Annotations are drawn on a canvas in your browser.
