Quick Answer: How to Sign a PDF Instantly
Signing a lease, employment offer, or freelance NDA does not require printing paper, finding a pen, and scanning the signed page back to your computer.
- Go to welovepdfs.com/sign-pdf on your phone, tablet, or PC.
- Drop your contract into the workspace.
- Draw your signature with your finger or mouse, or choose a stylized typed cursive font.
- Position and resize your signature on the page, then download your finalized document.
Three Ways to Add Your Signature: Draw, Type, or Upload
Our signing workspace supports three flexible signature styles:
1. Draw by Hand
Use your finger or stylus on mobile screens, or drag your mouse on desktop. Our smooth Bezier smoothing algorithm turns hand gestures into natural ink strokes.
2. Type Cursive
Type your full legal name and choose from curated calligraphic script fonts that render an elegant, professional handwritten signature instantly.
3. Upload Scan
Sign a blank piece of paper, snap a photo, and upload the image. Our background removal filter automatically makes the white paper transparent.
Step-by-Step Signing Guide
- Upload the agreement: Drop your document into Sign PDF.
- Create signature element: Click "Add Signature" and choose your preferred creation method.

- Add date and initials: Click "Add Text" to insert today's execution date, your printed name, or job title.
- Bake and download: Click "Sign & Download". The signature graphic is composited directly into the document's vector content stream.
Are Electronic Signatures Legally Binding?
Yes. In virtually all developed legal jurisdictions—including the United States (ESIGN Act, 2000), the European Union (eIDAS Regulation 910/2014), the United Kingdom, Canada, and Australia—an electronic signature holds the same legal standing as a wet-ink pen signature on paper.
Courts verify three criteria:
- Intent to Sign: The signer intentionally attached their mark to approve the terms.
- Consent to Electronic Business: Both parties agree to execute agreements digitally.
- Retention & Reproducibility: The resulting contract is stored and reproducible by all parties.
Why Signing Locally Protects Your Signature from Theft
Your handwritten signature is your personal legal stamp. When you upload a PNG of your signature to commercial cloud signature portals, that image is stored indefinitely in third-party database tables, making it vulnerable to unauthorized access or rogue employees.
Because WeLovePDFs runs 100% inside your browser using client-side WebAssembly, your signature graphic is rendered locally in RAM and baked directly into your PDF. Zero image data is ever stored on any server.
