Then draw and place your signature
Tip: after choosing a page, click the preview where the signature should go.
Quick answer: To sign a PDF online free, add the document, draw your signature with your finger or mouse (or type your name in a script style), pick the page, click the preview exactly where the signature should sit, and press Apply & download. Everything stays on your device.
Printing a contract, signing it with a pen, and scanning it back is a 2010 workflow. This tool lets you draw your real signature on a touchscreen (or type it in a handwriting style), then place it precisely on the signature line of any page – tap the live preview and the signature lands where you tapped.
Because contracts, offer letters and agreements are exactly the documents you should never upload to random servers, this signer works fully client-side: the PDF, the preview and your signature image are all processed in your browser tab only. Note that this adds a visual signature (what most everyday paperwork needs); it is not a cryptographic digital certificate.
How to sign a PDF
- Add your PDF and wait for the page preview.
- Draw your signature in the signature box – or switch to Type and enter your name.
- Select the page, then click/tap the preview exactly where the signature should go; adjust size with the slider.
- Click Apply & download to save the signed PDF.

Honest limitations
- This creates a visible ink-style signature, not a certificate-based digital signature – fine for everyday agreements, but some government portals require certified e-signatures.
- One signature placement per run; run the tool again to sign multiple spots or pages.
- Locked PDFs must be unlocked first.
Frequently asked questions
Is a drawn signature legally valid?
In many situations, yes – most jurisdictions (including under Pakistan's Electronic Transactions Ordinance and similar laws elsewhere) accept electronic signatures for ordinary contracts when both parties intend to sign. For court filings or documents requiring certified digital signatures, check the specific requirement first.
How do I get a transparent signature?
It is automatic. The drawing canvas exports as a transparent PNG, so only your ink appears on the document – no white box.
Can I save my signature for next time?
For privacy, we don't store anything. A quick tip: after drawing once, screenshot or download the signed PDF; you can re-draw in a few seconds on your next document.
The signature appears in the wrong place – why?
Placement uses your exact click point on the preview as the signature's center. Zoomed browser views can shift perception, so click precisely on the signature line and use the size slider to fit.
Does the recipient see anything different?
They receive a normal PDF with your signature flattened onto the page – it looks identical everywhere and cannot be accidentally moved.
