Why Sign PDFs Online?
Signing documents used to mean printing, signing, scanning, and emailing back β a 10-minute hassle for a 3-second signature. Modern e-signatures eliminate all of that. You draw your signature once, place it on the PDF, and download β done in 30 seconds. For freelancers, small business owners, and anyone who signs contracts regularly, this saves hours every month.
How PDF Signing Works
A signature is an image. Our tool gives you two ways to create it: draw directly with mouse or finger (uses HTML canvas), or type in a script font (rendered as text). The signature is then embedded into the PDF as a transparent PNG image and placed at your chosen position and size on a specific page. Unlike digital certificates, this is a visual signature β it looks like your handwritten signature.
E-Signature vs Digital Signature
These are often confused. An e-signature (what this tool creates) is a visual representation of your signature β legally binding in most business contexts. A digital signature uses cryptographic certificates to verify identity and detect tampering β used in banking, government, and legal filings. For everyday contracts, invoices, and agreements, an e-signature is sufficient and standard.
Legal Validity of E-Signatures
In India, e-signatures are valid under the Information Technology Act, 2000, for most commercial transactions. In the US, the ESIGN Act and UETA give e-signatures the same legal weight as handwritten ones. In the EU, eIDAS regulations recognize e-signatures. As long as both parties agree to the transaction, an e-signature is legally binding for most business purposes. For wills, adoption papers, and some court filings, wet signatures are still required.
