How to Sign a PDF Free Without Adobe Acrobat
Add your signature to a PDF for free without Adobe Acrobat or any paid software. Draw, type, or upload your signature in any browser.
Adobe Acrobat used to be the standard way to sign PDFs, but at £17.99/month it is expensive for a task that should be simple and free. FixMyPDF's signature tool lets you draw, type, or upload a signature image and embed it in any PDF — no account, no subscription.
Three Ways to Add Your Signature
Draw: use your mouse, trackpad, or touchscreen to draw your signature directly. This produces the most natural-looking result. Type: enter your name and choose a handwriting-style font. Upload: if you have a PNG of your signature (transparent background works best), upload it as an image signature.
Step-by-Step: Sign a PDF Without Adobe
Go to fixmypdf.in/tools/pdf-sign. Upload your PDF. Choose your signature method (draw, type, or upload). Position the signature on the page — drag to move, resize as needed. Navigate to other pages if you need to sign in multiple places. Download the signed PDF.
Is This Legally Binding?
Electronic signatures created by adding an image of a signature to a PDF are legally valid in most jurisdictions for standard business documents — contracts, agreements, forms. This is equivalent to printing, signing, and scanning. For documents requiring qualified electronic signatures (certain regulated financial, legal, or government contexts), a dedicated eSignature platform with identity verification is required.
Signing on Mobile
On iPhone or Android, open the tool in your browser, upload the PDF, and use your finger to draw your signature on the touch screen. This produces a natural-looking handwritten signature.
Privacy
Your document and signature are processed entirely in the browser. Neither the PDF nor the signature image is sent to any server.
