3 Ways to Create Your Signature

Draw your signature: Use your mouse to draw naturally, just as you would with a pen. On a touchscreen device (phone, tablet), use your finger or stylus for an even more natural signature. This produces the most authentic-looking result.

Type your signature: Type your name and select from several handwriting-style fonts. This is the fastest option and looks professional for most business documents.

Upload a signature image: Sign on white paper with a dark pen, photograph it (or scan it), upload the image. PDFBro automatically removes the background and isolates the signature stroke.

Placing Multiple Signatures and Initials

Many contracts require both a full signature on the final page and initials on each preceding page. PDFBro lets you add multiple signature instances to the same document.

Workflow: 1. Upload the document 2. Create your full signature 3. Place it on the signature line on the final page 4. Create your initials (draw just your initials) 5. Place them at each page's initial line

All signatures are embedded into one downloaded PDF.

Is an Electronic Signature Legally Valid?

In the United States, the ESIGN Act (2000) gives electronic signatures the same legal standing as wet ink signatures for most contracts and transactions. The EU eIDAS regulation provides equivalent recognition across Europe. Similar laws exist in the UK, Canada, Australia, and most countries.

Electronic signatures are valid for: contracts, NDAs, employment agreements, lease agreements, consent forms, and most business documents.

They may NOT be sufficient for: wills and trusts, court orders, real estate deeds (in some jurisdictions), and certain government forms. Always verify with a legal professional for high-stakes documents.

• 1

  Save your signature image as a transparent PNG after your first signing — reuse it directly via 'Upload' next time instead of redrawing.

• 2

  Use the Initials option for multi-page documents — create a smaller version of your signature for initialing each page.

• 3

  Dark ink on white paper gives the cleanest result when uploading a photo of your physical signature.
