Why Choose a No-Signup PDF Signer?
Most online PDF signing tools force you to create an account before you can even preview the tool. SigPDF is different — you can upload your PDF and start placing signatures immediately, with zero friction.
Your documents are processed entirely within your web browser using client-side JavaScript. We never upload your files to any server, making SigPDF one of the most private PDF signing tools available online.
No Watermark, Ever
Unlike many “free” PDF tools that add watermarks to your documents, SigPDF produces clean, professional signed PDFs without any branding or watermarks on your documents.
How It Works
- Upload your PDF by dragging and dropping or clicking to browse
- Draw your signature with your mouse or finger, or type your name
- Click anywhere on the PDF to place your signature
- Download your signed PDF — the signature is permanently embedded
