Screenshot annotator
Point things out with arrows, boxes, highlights, and numbered step markers, or pixelate private details before you share. Free, private, no sign-up.
Runs in your browser — nothing is uploaded
Drag to point at something
Redact overwrites the pixels in the exported PNG, so the original isn't kept in the file. Your image never leaves this tab.
Frequently asked
Is the screenshot annotator free?
Yes. It is completely free with no sign-up. Annotate and download as many screenshots as you like.
How do I blur or redact sensitive information in a screenshot?
Pick the Redact tool and drag over emails, names, API keys, or anything private. The area is pixelated and the original pixels are replaced in the PNG you download.
Are my screenshots uploaded anywhere?
No. Everything runs locally in your browser. Your image is never sent to a server.
How do I add numbered steps to a screenshot?
Choose the Step tool and click where each action happens. Markers number themselves 1, 2, 3 in the order you place them, which makes a single screenshot read like a mini how-to.
Can I turn a whole workflow into annotated steps automatically?
Yes. Steperly records a workflow once and produces every step as an annotated screenshot, plus a step-by-step guide, a walkthrough video, and an interactive demo.
Annotating step by step? Record it once instead.
