🔒 Free to use, and private because your privacy matters — your file opens right here in this browser tab, not on someone’s server, and never leaves your device.

The everyday office job: a contract lands in your inbox that needs initialing, a form arrives as a flat PDF with no fields to type into, or a supplier sends a quote you need to mark up before forwarding. This is where you handle all of that — no printing, scanning, or emailing a file to yourself to open on another app.

  • Add text — type directly onto a flat form or contract, no form fields required
  • Sign it — draw your signature once and drop it wherever it belongs
  • Mark it up — highlights, boxes, arrows and lines to flag what matters
  • Fix the pages — reorder, delete, extract, or merge in another PDF

Everything happens on your device, so a signed contract or a form full of personal details never gets uploaded anywhere. When you're done, hit Export and you've got a clean, finished PDF ready to send. New to it? The user guide and the how to sign a PDF walkthrough cover every step.

It works with the PDFs you already have — no conversion step, no “premium” wall on the useful features, and no watermark stamped across your export. Because it runs in the browser, it behaves the same on Windows, Mac, a Chromebook, an iPad or an Android phone: open the file, make your changes, export a finished copy. The three things most people come here to do — type on a flat form, drop in a signature, and tidy the page order before sending — are all on this screen, with nothing to install.
