No. Your PDF never leaves your device. Everything happens entirely in your browser using the PDF.js rendering engine and pdf-lib export library. Nothing is transmitted or stored anywhere.

You can add freeform text in any font size and colour, tick/checkmark symbols, today's date, and hand-drawn signatures. All annotations are placed at the exact pixel position you choose on any page.

Select the Signature tool, then click Draw / Update Signature in the sidebar. Sign with your mouse or finger on the pad, click Use Signature, then click anywhere on the PDF to place it. You can resize and reposition it freely.

This tool adds annotations on top of the PDF at any position — it works on any PDF whether or not it has interactive form fields. For PDFs with AcroForm fields, click directly on the field area and add a text annotation on top.

Hover over any annotation to reveal the red × button in its corner, then click it. You can also select an annotation and press Delete or Backspace.

Yes. Use the Previous / Next buttons in the sidebar to navigate. Each page has independent annotations. All pages with their annotations are included on export.

The tool uses pdf-lib to embed all annotations permanently into the PDF. Text, checkmarks, dates and signatures are written directly into the pages. The result is a standard PDF that opens in any viewer.
