Sign PDFs Electronically

Our free online PDF sign tool provides a simple way to add your signature to PDF documents without printing, signing by hand, and scanning. Whether you need to sign contracts, agreements, forms, or any other documents, our browser-based tool makes electronic signatures accessible to everyone. Simply upload your PDF, draw your signature using your mouse or touchscreen, and download the signed document.

Draw Your Signature

The signing tool features an intuitive canvas where you can draw your signature using mouse strokes or touch input. The signature is captured as a high-quality PNG image and then embedded into your PDF at the bottom right of the last page. The drawing canvas provides a smooth, natural signing experience that closely mimics signing on paper.

Client-Side Processing for Privacy

We understand that signed documents often contain sensitive information. Our PDF sign tool processes everything directly in your browser using JavaScript, meaning your documents and signatures never leave your device during the signing process. This ensures complete privacy for your personal signature and the documents you sign. No data is transmitted to external servers at any point.

Legality of Electronic Signatures

Electronic signatures are legally binding in most countries and industries. In the United States, the ESIGN Act and UETA provide legal recognition for electronic signatures. The European Union recognizes e-signatures under eIDAS. Many other countries have similar legislation. As long as the signature demonstrates intent to sign and is associated with the signatory, electronic signatures typically carry the same legal weight as handwritten signatures.

Common Use Cases

Electronic PDF signatures are widely used for contract signing, agreement execution, form submission, approval workflows, and any scenario requiring documented consent. Businesses use e-signatures for remote contract execution. Real estate professionals use them for digital lease signing. HR departments use them for remote employee onboarding documents. Our tool makes electronic signatures accessible without expensive software subscriptions.

Free and Instant Access

Our PDF sign tool is completely free with no watermarks, registration, or usage limits. Sign as many documents as you need without paying fees or creating accounts. The signed output is yours to use for any purpose, whether business contracts, personal agreements, or any document requiring your signature.
