PDF Pen — Sign & Fill Instantly

About

PDF Pen lets you sign, fill, and annotate PDF documents without ever leaving Chrome — and without uploading your files anywhere.

Unlike other PDF tools that require you to upload sensitive documents to their servers, PDF Pen works entirely on your device. Your contracts, tax forms, and personal documents never touch a remote server.

FEATURES

  Sign in Seconds
  Click "Sign PDF" on any PDF to open our clean, fast viewer. Type your name, pick from beautiful handwriting fonts, place your signature anywhere, resize it — done.

  Fill Forms & Add Text
  Click to place text anywhere on the page. Type directly on the document — perfect for filling in forms, adding dates, or writing notes. Multi-line support with Enter.

  Check Boxes
  One-click X marks to fill in existing checkboxes on any form or document.
