About the Free PDF Sign & Fill Tool

Need to sign a PDF or fill out a PDF form without printing, scanning or buying Acrobat? This free tool lets you draw a real signature, type text into any spot, and stamp a date — then flattens it all into a finished PDF, right on your device. It's perfect for the everyday American paperwork moment: an offer letter, a lease, a permission slip, a tax form, an NDA or a vendor agreement that needs your signature today.

Draw your signature once with a mouse, trackpad or finger and drop it onto any page at any size. Use Add text to fill names, dates, checkmarks and answers onto flat (non-fillable) forms, with adjustable font size and color. Everything is draggable, so you can line it up exactly over the signature line or form field before you download.

Unlike most "free" e-sign sites that upload your documents to a server and gate downloads behind an account, this tool runs 100% in your browser using the open-source pdf.js and pdf-lib engines. Your signature image and PDF never leave your computer or phone — nothing is transmitted, stored, or seen by anyone, which matters for legal, financial and HR documents. It works on Windows, Mac, iPhone, iPad, Android and Chromebook with no install.

Can I fill out a form that is not fillable? ▾

Yes. Use Add text to type names, dates, answers and checkmarks directly onto any flat PDF, with adjustable font size and color, then position each one exactly where you need it.

Is a drawn signature legally valid? ▾

Does it work on iPhone, iPad, Android and Mac? ▾
