Add your signature to any PDF document online for free. Draw it with your mouse or finger, type it with a signature font, or upload a signature image. Place it on any page, resize, and download. No upload, no account needed.
Add Your Signature to Any PDF
Upload your PDF and place a signature anywhere on any page. Draw freehand with your mouse, trackpad, or touchscreen. Type your name and choose from signature-style fonts. Or upload an existing signature image (PNG, JPG, SVG). Position it on the signature line, resize to fit, and download the signed document.
Draw, Type, or Upload Your Signature
Three ways to create your signature. Draw it freehand for the most natural look - works great on touchscreen devices. Type your name and pick a handwriting-style font for speed. Or upload a scanned signature image you already have. Each method produces a clean result that looks professional on the document.
Sign PDF Without Uploading to a Server
Your PDF and signature data stay entirely in your browser. Nothing is sent to any server - no cloud processing, no temporary copies, no third-party access. Sign contracts, NDAs, agreements, and personal forms with complete privacy. Close the tab and everything is gone.
Flatten After Signing
After adding your signature, use Flatten PDF to make it a permanent part of the page. This prevents the signature from being moved or removed. For extra security, use Protect PDF to add password protection before sharing the signed document.
