The Sign PDF tool allows you to securely add legally recognized electronic signatures to any document. Whether you need to sign contracts, invoices, NDAs, forms, or agreements, this tool provides a complete visual signature solution. You can draw your signature using mouse or touch, type your name with professional fonts, or upload an image of your handwritten signature. Add signature dates, specify signer identity, and even password-protect the signed document. All operations are performed online without printing, scanning, or installing software — saving time, paper, and ensuring document integrity.
Use your mouse, trackpad, or touchscreen to draw your signature naturally. The tool captures every stroke precisely, preserving the unique characteristics of your handwritten signature. You can adjust stroke thickness, color (black, blue, or red), and background transparency. After drawing, you can reposition the signature anywhere on the page and resize it without losing quality. This method is ideal for tablets, touchscreen laptops, or anyone who prefers a handwritten look without printing.
If you need a clear, legible signature, choose the type option. Select from over 20 cursive and handwriting-inspired fonts (e.g., Segoe Script, Brush Script, Great Vibes). Customize font size, color, and style (bold/italic). Typed signatures are perfect for formal business documents, reports, and digital forms where readability matters more than a drawn signature. You can also combine typed name with a drawn initial for hybrid authentication.
Upload a scanned image or photo of your actual handwritten signature (PNG, JPG, or transparent background). The tool automatically removes white backgrounds, preserves transparency, and optimizes resolution. You can crop, resize, and rotate the uploaded signature. This method offers maximum authenticity because you use your real, legally binding signature exactly as it appears on paper documents. Ideal for notaries, executives, and legal professionals.
Every signed document should include a date. You can insert today’s date automatically (based on your system timezone) or enter a custom date. The date can be positioned near the signature or anywhere on the page. Choose date formats (MM/DD/YYYY, DD/MM/YYYY, or YYYY-MM-DD). Including the date creates a verifiable timeline and is often required for legal enforceability under e-signature laws (ESIGN, eIDAS).
Beyond the signature itself, you may need to add the signer’s printed name, job title, company name, or “Signed by” label. The tool provides text boxes that you can place anywhere on the document. Customize font, size, color, and alignment. This feature transforms a simple signature tool into a complete document completion tool, allowing you to fill in missing information before signing.
Some documents require multiple signatures – for example, contracts with two parties, approval workflows with manager and director, or multi-page agreements. You can add as many signature fields as needed, each with different styles (drawn, typed, or uploaded). You can also sign the same document at different locations (e.g., signature on page 1, initials on page 3, and date on final page). All signatures are independent and can be added sequentially.
After adding a signature, you can drag it to any location on the page, resize it by dragging corners, and rotate it in 15-degree increments. The visual editor shows real-time preview, so you always know exactly how the final PDF will look. This flexibility ensures your signature fits perfectly into designated signature boxes, regardless of the original PDF layout.
For sensitive documents, you can add a password after signing. The tool encrypts the PDF with AES-256, requiring the recipient to enter the password to open, view, or print the file. You can also set permissions (e.g., allow printing but disable editing). This is crucial for contracts containing personal data, financial information, or trade secrets. The original unsigned document remains unprotected – only the signed output is secured.
Long contracts often require initials on every page to confirm review. The tool includes a dedicated “Initials” mode with smaller signature fields. You can create a simplified initial signature (e.g., two letters) and then click “Apply to All Pages” to place it on every page automatically. You can also manually add initials to specific pages. This saves enormous time when signing 20+ page agreements.
If you frequently sign documents, you can save your signature (drawn, typed, or uploaded) to your browser's local storage. The next time you use the tool, your saved signature appears instantly. You can manage multiple saved signatures (e.g., personal signature, company signature, proxy signature). This feature dramatically speeds up repeated signing tasks like daily invoices, approval forms, or batch document processing.
All signatures are added with transparent backgrounds by default, meaning they overlay seamlessly onto the PDF without covering existing text or lines. You can adjust opacity (10% to 100%) to create a watermark-like effect or a solid signature. Transparency ensures that your signature integrates naturally, just like ink on paper.
Made a mistake? Use undo/redo buttons to step back through signature placements, text additions, or date changes. You can also clear all signatures from the current page or the entire document with one click. These controls give you full confidence to experiment without fear of ruining the document.
After adding all signatures, dates, and text fields, click “Sign PDF” to generate the final document. The signed PDF is downloaded directly to your device. The tool does not store your documents, signatures, or any data on its servers. All processing happens locally in your browser for maximum privacy and security. Your original unsigned file and your signature image are never uploaded to any cloud.
Even if your PDF is a scan of a physical document or a photo converted to PDF, the signature tool works perfectly. You can add digital signatures on top of scanned paper forms, eliminating the need to print, sign by hand, and scan again. This is a massive time saver for remote work, real estate documents, medical forms, and legal paperwork.
The signatures created with this tool are legally binding in most countries. Electronic signatures that include intent (e.g., clicking “Sign”), consent, and attribution (timestamp + signature image) satisfy the US ESIGN Act, EU eIDAS regulation, and UETA. For higher assurance, you can combine the signed PDF with an audit trail (download the signed PDF plus a separate timestamp log). The tool does not provide digital certificates (PKI) but is suitable for 95% of business and personal signing needs.
Our Sign PDF tool offers multiple signature methods, customization options, and legal compliance features for professional document signing.
