FAQ

Questions, answered

How do I annotate a screenshot in Chrome?

Install Snap, open it on the page and press Snap. Press Finish to open the editor, then use Rectangle (R), Arrow (A), Text (T) or Redact (B) to mark up the capture. Export a PNG or PDF, or paste the flow into Figma.

Can I blur or hide sensitive information?

Yes. The Redact tool pixelates any area you draw over, and the pixelation is applied in every PNG, ZIP, PDF and Figma export. Pixelation hides details from casual viewing but is not a guarantee, so avoid capturing passwords or secrets at all.

Are my original screenshots changed?

No. Annotations are stored separately with each step, so the original capture stays untouched in the editor. You can move, edit or delete annotations at any time.

Can I annotate a whole flow, not just one screenshot?

Yes. Every step in a flow can have its own boxes, arrows, text and redactions, and the whole annotated flow exports together as a PDF, a ZIP or a Figma paste.

Is Snap’s annotation tool free?

Yes. Snap is free in the Chrome Web Store, with no account and no sign-up. Your screenshots and annotations stay in your Chrome profile.
