How to sign a PDF

PDFDistrict adds your signature as an image on the page you choose. Draw it with a mouse, finger or stylus, or type your name and pick a style. A preview of the page lets you drag the signature into position and resize it; tick “Apply to all pages” if you want it (for example, as initials) on every page.

A step-by-step version: how to sign a PDF for free.

Practical use cases

Signing a form or agreement that was sent as a PDF.
Initialing every page of a document.
Signing from a phone without installing an app.

What this signature is — and isn’t

This adds a visible signature image to the page. It is not a certificate-based digital signature and it does not verify your identity. Whether a visible signature is accepted depends on who is asking for it; for documents that require a verified or certified signature, use a service designed for that.

Common problems

Click “Sign PDF” and nothing downloads: the signature box is empty — draw or type a signature first.
The typed signature looks different on another device: the three typed styles use fonts available on your device; what you see in the box and the preview is what is placed in the PDF.
The signature is too small or large: drag the page preview position, and adjust the size so it fits the signature line.
