Description
Drag over any part of a page → get a PDF stamped with URL, title & time. For QA, audits & compliance. 100% local. Stop typing timestamps onto screenshots. ProofStamp turns anything visible in your browser into a professional, labelled PDF evidence document — in one drag. How it works 1. Click ProofStamp and drag over the part of the page you need 2. Check the preview, add an optional label ("TC-1142 fail") 3. Download a PDF stamped with the page URL, title, and capture time (local + UTC) Why people buy it • Report-ready: A4 PDF with a clean metadata block — paste straight into audit or QA documentation • Accurate: capture time recorded in local time AND UTC • Fast: about 20 seconds from "I see it" to saved proof • PNG option when you just need the pixels Private by design Everything happens on your computer. No accounts, no uploads, no tracking, no analytics. The only network request this extension can make is checking your license key with Gumroad when you activate. Permissions, in plain English "Read the page you're on when you click" (activeTab/scripting) — used only to show the selection overlay and capture your chosen region. "Downloads" saves your file. "Storage" remembers your settings locally. Free trial, one-time price Your first 3 captures are free with every feature. Unlocking forever costs $7.99 once — no subscription, no account. License keys are delivered instantly by Gumroad. What it doesn't do (on purpose) No full-page scrolling capture, no cloud sync, no editing suite, no legal chain-of-custody claims. One job, done extremely well. Support: onceworks.tools@gmail.com — I answer fast. FAQ Q: Does it work offline? A: Yes — capture and PDF creation are fully local. Q: Where are files saved? A: Your Downloads folder. Q: New computer? A: Paste the same license key from your Gumroad receipt.
