Built for visible feedback
A note next to a paragraph, a circle around a number or a signature image can be more useful than editing the document itself. You can adjust added marks before exporting a copy.
Built to keep files local
The browser editor reads a chosen PDF on your device. The Chrome extension can fetch a public linked PDF directly from its source site with a site-specific permission. Reusable signature images stay in browser storage.
Built with explicit boundaries
The editor can change the PDF’s own text, but it does not remove confidential content from the file: whiteout only covers it. For that, use a verified redaction tool. A visual signature is not a cryptographic signature.
