Sign X PDF

Sign a PDF in your browser

Sign X PDF lets you add a visible signature to a PDF directly in your browser. The PDF is processed locally on your device instead of being uploaded to Sign X PDF servers. No account is required. When you finish, save the updated PDF to your device.

Your PDF is processed locally in your browser and is not uploaded to Sign X PDF servers.

What this tool does

Create a signature by drawing, typing, uploading an image, or using the camera where available, then place it on the page and export a new PDF.

Open a PDF or supported image.
Create or choose a signature (draw, type, upload, or camera).

Signature creation and PDF export run with client-side libraries in your browser after the page assets load.

FAQ

Q1 Is this a certificate-backed digital signature?

A1 No. Sign X PDF places a visible signature (drawn, typed, or image). It does not apply certificate-based cryptographic signing, timestamping, or signature verification.

Q2 Is the PDF uploaded to sign it?

A2 No. Signing is designed to run locally in your browser. Ordinary site assets still download over the network.

Q3 Can I use a photo of my signature?

A3 Yes. You can upload a signature image or capture one where your browser allows camera access.

Q4 Is drawing on a PDF the same as a digital signature?

A4 No. Drawing places a visible mark. A certificate-backed digital signature uses cryptography and a digital certificate. Sign X PDF only places visible signatures.
