June 6, 2026 · By PDFWinner Team

There are three quick ways to add your signature to a PDF — draw it, type it, or upload a photo. Here’s how.

Below we cover exactly how to do it — free, in seconds, and entirely in your browser. Because everything runs on your own device, it works the same on Windows, Mac, Linux, Android and iPhone, with nothing to install and no account to create.

Why adding a signature to a pdf matters

Getting this right saves time and avoids the usual headaches — files that are too big to send, broken formatting, or documents that look different on someone else’s screen. With Sign PDF the process is quick and repeatable, and your documents stay private because they are never uploaded to a server.

Draw, upload or type

Create your signature by drawing it, uploading a photo of it, or typing your name in a signature font.

Place it precisely

Drag the signature onto the exact spot and resize it before exporting.
