Why Use Sign PDF Online?

Three Signature Methods

Choose how to create your signature: draw freehand with mouse or touchscreen, type your name with professional script fonts, or upload an existing signature image. Switch between methods anytime to find what works best.

Precise Positioning

Place your signature exactly where you need it. Use preset positions (bottom-right, bottom-left, center) for quick placement, or use custom coordinates to position anywhere on the page with pixel-perfect accuracy.

Flexible Page Selection

Sign all pages, just the first page, only the last page, or select specific pages individually. Perfect for contracts where you need to initial every page or sign only the signature page.

100% Privacy Guaranteed

Your documents and signatures are processed entirely in your browser. Nothing is uploaded to any server. When you close the tab, all data is gone. Safe for signing confidential contracts and sensitive legal documents.

How It Works

Upload Your PDF

Drag and drop your PDF document into the upload area or click to browse. The tool loads your PDF and shows a preview so you can see exactly where your signature will appear.

2

Create Your Signature

Choose your preferred method: draw freehand on the canvas, type your name and select from 5 elegant script fonts, or upload an existing signature image. Adjust size and color to match your preference.

3

Position & Select Pages

Choose where to place your signature using presets or custom positioning. Select which pages to sign: all pages, first only, last only, or pick specific page numbers.

4

Sign & Download

Click Sign PDF to apply your signature. Preview the result, then download your signed document. The original filename is preserved with '_signed' appended for easy identification.

Tips for Better Signatures

Draw on Tablet for Best Results

If available, use a tablet with stylus for the most natural-looking drawn signatures. The larger drawing area and pen precision create signatures that look hand-drawn.

Always Add the Date

Enable the Date element to add today's date automatically. Choose from 5 formats to match your document's style. Dated signatures are more legally complete.

Add Printed Name for Clarity

Enable Printed Name to add your typed name below the signature. This makes it clear who signed, especially if your handwritten signature is stylized.

Use Initials for Multi-Page Contracts

For contracts requiring initials on every page, enable the Initials element. Use auto-generate from your printed name, or type them manually.

Review Before Signing

Always read documents completely before signing. Electronic signatures are legally binding. Once signed, the document represents your agreement to its terms.

Frequently Asked Questions

Click the 'Draw' tab in the signature creation panel. Use your mouse on desktop or finger on touchscreen devices to draw your signature on the canvas. The tool captures smooth strokes with natural-looking line quality. If you make a mistake, click Clear to start over. When satisfied, click 'Use This Signature' to save it. Your drawn signature is then ready to place on your PDF document.
We offer 5 professionally-designed script fonts: Script (Dancing Script) for classic cursive, Elegant (Great Vibes) for formal occasions, Formal (Allura) for business documents, Bold (Pacifico) for a distinctive look, and Simple (Caveat) for casual handwritten style. All fonts are Google Fonts, rendering beautifully on any device and embedding perfectly into your PDF.
Yes! Click the 'Upload' tab and select any image file (PNG, JPG, GIF). For best results, use a PNG with transparent background so only your signature appears without a white box. If your signature has a white background, it will still work but may be more visible on colored documents. The tool automatically scales your image to fit while maintaining quality.
Yes, in most jurisdictions. The U.S. ESIGN Act and UETA, along with the EU's eIDAS Regulation, recognize electronic signatures as legally binding for most business transactions. This includes contracts, agreements, approvals, and acknowledgments. However, some documents like wills, trusts, and certain government filings may require handwritten signatures. For high-stakes legal documents, consult with legal counsel about specific requirements.
In the 'Apply Signature To' dropdown, select 'Select Pages'. A grid of page numbers will appear. Click each page number you want to sign - selected pages highlight in blue. You can click again to deselect. This is perfect for contracts where you need to sign the final page and initial other pages, or for documents where only certain pages require signatures.
Yes! Below the signature creation area, you'll find color options: Black (traditional), Blue (common for legal documents), Navy (professional), and Red (for emphasis). Click any color to apply it. For drawn and typed signatures, the color applies immediately. For uploaded images, the original colors are preserved - use an image editor if you need to change colors before uploading.
Use the 'Signature Position' options. Quick presets include Bottom Right (most common), Bottom Left, and Bottom Center. For exact placement, select 'Custom Position' to reveal X and Y sliders. X controls left-right position (0% = left edge, 100% = right edge), Y controls top-bottom (0% = top, 100% = bottom). The live preview shows exactly where your signature will appear.
Absolutely. All processing happens 100% in your web browser using JavaScript. Your PDF and signature never leave your device - nothing is uploaded to any server. We use pdf-lib for PDF manipulation and pdfjs-dist for rendering, both running locally. When you close the browser tab, all data is permanently erased. This makes our tool safe for confidential contracts, legal documents, and sensitive business papers.
Electronic signatures are any electronic indication of intent to sign - like a typed name, drawn signature, or scanned image. Digital signatures use cryptographic certificates for verification and tamper-detection. Our tool creates electronic signatures, which are simpler and work for most purposes. For high-security needs requiring certificate-based verification (like government submissions), you'd need specialized digital signature software with PKI infrastructure.
Yes! After creating or uploading your signature, use the Size slider in the signature preview panel. Drag left to make smaller (minimum 50%), right to make larger (maximum 200%). The preview updates in real-time so you can see exactly how it will look on your document. This is useful for matching signature size to signature lines on forms or contracts.
Yes! The interface is fully responsive and touch-optimized. Drawing signatures works with finger or stylus on touchscreens - many users find this creates more natural-looking signatures than mouse drawing. The PDF preview and all controls adapt to smaller screens. For the best mobile experience, use a tablet for more drawing space, though phones work perfectly for quick signatures.
No, password-protected PDFs must be unlocked first. Use our Unlock PDF tool to remove password protection, then return to sign the document. If you don't have the password, you cannot sign the PDF (this is a security feature). After signing, you can re-protect the PDF with a new password using our Protect PDF tool if needed.
Your original PDF file is never modified. The tool creates a new copy with your signature embedded. The signed version downloads with '_signed' added to the filename (e.g., 'contract.pdf' becomes 'contract_signed.pdf'). Your original file remains unchanged on your device. This non-destructive approach means you always have the unsigned version available.
Currently, the tool adds one signature per signing session. For multiple signatures (like signing on page 1 and initialing on page 5), sign the document once, then upload the signed PDF and add the second signature. Each iteration creates a new signed version. We're working on multi-signature support for a future update where you can add several signatures in one session.
Yes! Enable the Date element in the 'Additional Elements' section. Choose from 5 date formats (MM/DD/YYYY, DD/MM/YYYY, YYYY-MM-DD, Month D YYYY, D Month YYYY), add an optional prefix like 'Date:', and position it independently anywhere on the page.
Yes! Enable the Printed Name element to add your typed name alongside your signature. You can add a prefix like 'Name:' or 'Signed by:', customize the font, size, and color, and position it exactly where you want.
Yes! Enable the Initials element to add your initials. You can type them manually or use the auto-generate feature that extracts initials from your printed name. Initials are commonly used for initialing each page of a contract.
Yes! The Custom Text element lets you add any text you need - job title, company name, license number, or any other information. Full styling control with font family, size, and color options.
Yes! Each additional element (Date, Name, Initials, Custom Text) has its own styling options: font family (Helvetica, Times Roman, Courier), font size (8-24pt), and text color. Position each element independently using X/Y sliders.
