Is this signature legally binding?

Electronic signatures created with this tool may be legally valid depending on your jurisdiction and the nature of the agreement. For critical legal documents, consult with a legal professional about the specific requirements.

Can I add multiple signatures to different pages?

Yes. Navigate through the document and add signatures to multiple pages independently. Each signature can be positioned and sized separately.

What file format is the signed document?

The signed document is a standard PDF file viewable in any PDF reader. The signature is flattened into the page as an image overlay.

Can I remove a signature after placing it on the page?

Yes. Before downloading, you can remove any placed signature and reposition it. Once downloaded, the signature is permanently part of the PDF.

Digitally sign PDFs using typed text, uploaded signatures, or freehand drawing

Beginner4 min read

Introduction

Sign PDF lets you add digital signatures to documents using typed text, an uploaded signature image, or freehand drawing with your mouse or touch device. There is no need to print, sign, scan, or fax anything — the entire signing process happens digitally in your browser. Electronic signatures are legally recognized in most jurisdictions under frameworks like the ESIGN Act (US), eIDAS (EU), and Kenya's Kenya Information and Communications Act. While Zilita's tool provides the signature placement mechanism, it is designed for informal to semi-formal document signing where a drawn or typed signature is acceptable. The signed PDF downloads as a standard PDF file that can be shared immediately. All processing runs client-side, so your unsigned documents and signature data never leave your computer. This is particularly important for contracts and agreements that contain confidential terms.

What the Tool Does

Upload any PDF, choose your signature method — type your name in a calligraphy font, upload an image of your handwritten signature, or draw your signature using a mouse or touchscreen. Position and resize the signature on the page, then apply it. You can add multiple signatures to different locations within the same document. The tool embeds the signature as a transparent PNG overlay on the PDF page at the coordinates you specify. You can also add a date stamp and optional signing location text below the signature. The final document is flattened into a new PDF, ensuring the signature appears correctly in any PDF reader regardless of fonts or system capabilities.

Why It Is Useful

The traditional sign-print-scan cycle adds hours or days to document workflows. An agreement that could be signed in 30 seconds takes a full day when it involves printing, manually signing, scanning, and emailing back. Digital signature tools eliminate all of that friction. For freelancers, remote teams, and businesses that handle frequent agreements, the time savings are substantial.

Practical Examples

Signing a Freelance Contract

A graphic designer receives a two-page client agreement via email. Instead of printing and signing, they upload the PDF to Sign PDF, type their name in the calligraphy font, add the date, and email the signed document back within two minutes.

Approving an Internal Request

A department head needs to approve a purchase requisition PDF. Using a tablet, they draw their signature freehand on the signature line, add a date stamp, and forward the signed PDF to the finance team immediately.

Benefits

Eliminates the print-sign-scan cycle, reducing signing time from hours to minutes
Three signature methods accommodate different comfort levels and device capabilities
No account creation or subscription fees — sign as many documents as you need
Client-side processing keeps contract contents and signature data private
Signed documents are standard PDFs compatible with all PDF readers

Tips

For a professional look, use the typed signature option with the cursive font — it reads as a signature while being perfectly legible.
If uploading a signature image, use a PNG with a transparent background on white paper for the cleanest result.
Draw signatures slowly for the smoothest result. Fast mouse movements produce jagged lines.
Add a date stamp to create a clearer record of when the document was signed.

Frequently Asked Questions
