How to Sign a PDF Without Adobe Acrobat (Free, Legal)
Add an electronic signature to a PDF without Adobe Acrobat or DocuSign — free, browser-based, legally valid. Draw, type, or upload your signature.
Adobe Sign costs $22.99+/month. DocuSign starts at $15/month. For personal and small business PDF signing, FixMyPDF is a completely free alternative — no subscription, no account, no limits on how many PDFs you sign.
What You Need to Sign a PDF Without Acrobat
Just a modern browser. Go to fixmypdf.in/tools/pdf-sign on any device. Upload the PDF. Create your signature (draw, type, or upload an image of your handwritten signature). Position it on the document. Download the signed PDF. No software needed beyond your browser.
Is a Browser-Based Signature Legally Valid?
Yes — in most jurisdictions. The US ESIGN Act (2000) gives electronic signatures the same legal weight as handwritten ones for most contracts and agreements. EU eIDAS regulation similarly recognises electronic signatures. The key requirement is intent to sign and some form of authentication — clicking "Download Signed PDF" demonstrates both.
Three Signature Methods
Draw with your mouse, trackpad, or finger for a natural handwritten look. Type your name in a cursive font for a clean professional signature that's widely accepted. Upload a photo of your handwritten signature on white paper for the most authentic appearance. All three are available free in our tool.
Acrobat Sign vs FixMyPDF for High-Stakes Documents
For mortgages, wills, notarised documents, and high-value contracts, a certified e-signature platform (Adobe Sign, DocuSign) provides an audit trail, signer verification, and tamper detection that proves who signed and when. For everyday contracts, NDAs, forms, and approvals, our free tool provides a legally valid signature.
Built-In Signing Tools on Mac and Windows
Mac's Preview has a built-in signature tool (Markup → Signature). Windows Edge has a Draw tool that works for basic signing. Both are free options — our tool adds the "Type" and "Upload" signature methods that built-in tools lack, plus more precise positioning controls.
No Watermarks on Signed PDFs
Unlike DocuSign's free preview tier which adds a DocuSign logo to all documents, our tool produces a clean signed PDF with only your signature and no promotional content from us.
