Screenshot Annotator
Add arrows, boxes, text, and blur — all in your browser.
About this tool
Most screenshots need two things before anyone else sees them: something pointing at the part that matters, and something covering the part that should not be public. This does both — arrows, boxes, and text to direct attention, blur to hide customer names, email addresses, and billing details.
It runs entirely in your browser on a canvas. Nothing is uploaded, which is the point when the screenshot contains production data.
Common questions
Is the blur reversible?
No. The blur is rasterised into the exported image rather than stored as a layer, so the original pixels are gone in the file you download. That is what you want for redaction — a blur applied as an overlay in some editors can be peeled off by anyone who opens the source file.
Does my screenshot get uploaded?
No. Editing and export both happen locally via the canvas API, so the image never leaves your device.
What should I redact before sharing a product screenshot?
Customer names and emails, billing and card details, API keys and tokens, internal URLs and subdomains, and anything in a browser address bar or notification. Session identifiers in URLs are the one people forget most often.
