No Windows computer? Use pdfsign in your browser, on any phone or computer. Your files stay on your device.
Contracts, forms, rental agreements, tax papers: the documents you sign are the ones you least want on someone else's server. pdfsign opens them on your own computer, lets you sign, fill in and tidy them up, and saves the result next to the original. Nothing is uploaded, because there is nowhere for it to go.
The problem
The trouble with signing a PDF
Your papers on a stranger’s server
Most signing websites upload the document to sign it: your contract, your address, your ID number.
The print, sign and scan shuffle
The alternative is a printer, a pen and a scanner, and a crooked grey copy at the end.
How it works
Signed in three steps
Open the PDF
Drag it in. It opens on your computer, not on a website.
Fill in and sign
Type into the form, place your signature, add the date and your initials.
Save it
The signed copy is saved next to the original, ready to send.

Questions
Before you download
How can I check that it really doesn’t send my files anywhere?
Unplug your network cable or turn off wifi: pdfsign works exactly the same. For a closer look, open Windows’ Resource Monitor while you use it. Its only connections are to 127.0.0.1, your own computer. In the browser version, open it once, then turn on airplane mode: you can still open, sign and download PDFs, because it all happens on your phone or computer.
Can I use it on my phone?
Yes. Open pdfsign in your phone’s browser. It works on Android and iPhone, with nothing to install; your browser can add it to your home screen if you like. Your saved signatures and profile are kept in that browser, so clearing your browsing data deletes them.
Is it really free?
Yes. Every feature works, with no licence key, no trial, no watermark and no ads, and there’s no account to sign up for. It used to be sold; now it’s simply free.
Windows says “Windows protected your PC”. Is it safe?
Yes. The installer sets pdfsign up just for you, with no administrator password. Because it comes from a small independent developer, Windows may show that blue box the first time: click More info, then Run anyway. Windows shows it for new programs it hasn’t seen many times before, not because anything is wrong with the file.
Do I get updates?
Yes. Every new version of pdfsign is free too. Download it from this page and install it over the old one; your files carry on. The browser version updates itself.
Mac or Linux?
The app you install is for Windows, but the browser version runs on a Mac or Linux too.
