Inserting a digital signature into a PDF offers a secure, efficient method to confirm authorship, protect content, and eliminate physical paperwork.

First, load the document you need to sign through the WPS PDF application.

The Sign function can be accessed via the top ribbon interface once your document is ready.

This section provides choices for generating a fresh signature or selecting one you’ve saved before.

Begin by choosing Create Signature if you haven’t set up a signature yet.

Sign by hand with your mouse or touch device, input your name for an automated elegant version, or import a scanned image of your actual handwritten mark.

After creating your signature, position it where you want it to appear on the document.

You can adjust the scale and orientation of your signature to fit perfectly.

When ready, press Apply to permanently seal the signature into the file.

You may save a new version of the document or directly update the existing file with the signed copy.

Digital signatures created with WPS PDF are encrypted and tamper proof, meaning any alteration to the document after signing will invalidate the signature and alert recipients.

Your digitally signed documents remain legally enforceable and verifiable across jurisdictions.

You can insert several signature boxes, perfect for multi-party agreements, NDAs, or wps官网 team-based forms.

Enhance your signature with an embedded date and time marker for audit clarity.

After signing, you can review the signature status through the Signature Panel, which displays information about each signer and the timestamp.

You can save your signed files as PDF, JPEG, or PDF.

From contracts and invoices to applications and agreements, WPS PDF digitizes your signing process — cutting costs, protecting data, and accelerating delivery.

With military-grade encryption and user-friendly controls, WPS PDF stands out as the ideal solution for both personal and enterprise-level document signing needs.
