About PDF Signature Tool
What is the PDF Signature Tool?
The PDF Signature tool is a secure web utility that lets you add professional handwritten or electronic signatures to your PDF documents. Simply upload your PDF, create your signature using drawing tools, styled typing fonts, or image uploads, position it visually on your document, and download your signed file instantly.
Draw Signature Mode
The Draw signature option lets you use your mouse, laptop trackpad, or touch screen on mobile devices/tablets to write out your signature. Adjust ink color (Black, Blue, Red) and stroke thickness to replicate your natural handwriting. Make changes easily with convenient clear and undo controls.
Type Signature Mode
The Type signature option generates elegant, professional handwritten signatures based on the name you type. Select from a variety of distinct cursive script fonts to match your personal style. The tool renders your name into a high-quality signature image with a transparent background, ready for document placement.
Upload Signature Image
The Upload option allows you to import an image of your signature. If you have a scanned or photographed copy of your physical signature, you can upload it (ideally in transparent PNG format, though JPG works too). The tool processes the image, allowing you to scale and place it onto your PDF page.
Interactive Click-to-Place Positioning
Avoid the headache of guess-work coordinates. Our tool renders a high-quality visual preview of your PDF document. Just click anywhere directly on the page preview, and the signature box will move instantly to that exact spot. You can adjust dimensions and fine-tune locations before finalizing.
100% Secure Client-Side Execution
All PDF rendering and editing are performed locally on your device. We use browser-native rendering engines (`pdfjs-dist`) and local binary editors (`pdf-lib`) to handle the PDF. Your files and signatures are never uploaded to any server or cloud database. Your privacy and security are fully guaranteed.
Are Electronic Signatures Legally Binding?
Yes! In most regions worldwide (including under the US ESIGN Act and the EU eIDAS regulations), simple electronic signatures are considered legally binding for general agreements, invoices, HR documents, NDAs, and business proposals. For highly specialized deeds or wills, verify local regulations.
No Limits, Completely Free
Sign as many documents as you need with no subscription fees, registration prompts, or limits on usage. The tool is open-access and operates with no watermarks, retaining the pristine formatting and layout of your original PDF. Share your signed files immediately with clients, vendors, or colleagues.
