Sign PDF Documents Online — Free & Private
Signing PDF documents used to require printing, signing by hand, scanning, and emailing back. The DoctorDocs PDF Signer eliminates every one of those steps. Open your PDF, draw or type your signature, place it on the page, and download the signed document — all within your browser.
Unlike cloud-based e-signature services that upload your sensitive contracts to third-party servers, DoctorDocs processes everything locally using client-side JavaScript. Your NDAs, rental agreements, employment contracts, and legal filings never leave your device. No account needed, no subscription, no file size limits.
Key Capabilities
Three ways to sign
Draw freehand with a mouse, trackpad, or touchscreen; type your name in one of four handwriting-style fonts (Elegant, Classic, Modern, Casual); or upload a photo of your physical signature.
It's a visual signature, not a cryptographic one
The signature is stamped onto the page as an image, the same way a scanned wet signature would look on paper. If a document specifically requires a PKI-based digital signature, check what your counterparty or jurisdiction actually needs first.
100% local processing
Your PDF and signature are processed entirely in your browser. Nothing is uploaded to any server — relevant for NDAs and confidential contracts.
Multi-page placement
Navigate through a multi-page PDF and place the signature on any page — useful for contracts that need a signature on more than one page.
How to Use

Frequently Asked Questions
Is an electronic signature added here legally binding?
Yes. In most jurisdictions including the US (ESIGN Act), EU (eIDAS Regulation), and India (Information Technology Act 2000), electronic signatures applied with clear signer intent are legally recognized for most agreements and business contracts.
Are my signed documents stored on your servers?
No. The entire PDF signing workflow operates 100% client-side in your browser. Your confidential agreements, NDAs, and financial paperwork are never uploaded or retained.
Can I draw, type, or upload an image of my signature?
Yes. DoctorDocs lets you draw your signature using a trackpad, mouse, or stylus; type your name in elegant calligraphic script; or upload a clean PNG scan of your physical handwritten signature.
Can I sign multiple pages within the same PDF?
Yes. You can navigate through all pages of your multi-page document and place your signature, initials, or the current date wherever required before downloading.
