FAQ
Can I edit or remove a mark after drawing it?
Yes. Switch to the Select tool to drag any mark to a new spot or delete it, and double-click a text label to reword it. Every change can be undone and redone with the buttons or Ctrl / ⌘ + Z.
Which marks can I add?
Rectangles, circles (ellipses), arrows, numbered step badges, text labels and a freehand pen. Each one can use any color, an adjustable thickness, and a solid or dashed line style.
Will the marks stay sharp at full resolution?
Yes — annotations are rendered onto the image at its own resolution when you export, so a mark keeps exactly the thickness you saw in the editor, even on 4K screenshots.
Is my image uploaded anywhere?
No. The editor runs entirely in your browser and the annotated image is saved directly to your device — nothing is ever uploaded.
