Signature Placement Tips

  • Find the signature line: Most documents have designated signature areas, usually at the bottom of pages
  • Adjust size appropriately: Signatures should be 150-250 pixels wide and 50-100 pixels tall for standard documents
  • Test placement: Preview the signed PDF before sharing to ensure proper positioning
  • Add date if needed: Some documents require a date alongside the signature

Electronic vs Digital Signatures

It's important to understand the difference:

  • Electronic Signature (eSignature): Any electronic process indicating acceptance of a document. This tool creates eSignatures that are legally valid for most purposes.
  • Digital Signature: A cryptographic signature using certificates and public key infrastructure (PKI). Required for specific legal and regulatory scenarios.

For most business, personal, and even many legal documents, an electronic signature created with our tool is perfectly acceptable and legally binding.

Legal Validity

Electronic signatures created with our tool are legally valid under:

  • ESIGN Act (USA): Electronic signatures have the same legal standing as handwritten signatures
  • UETA (USA): Uniform Electronic Transactions Act recognizes electronic signatures
  • eIDAS (EU): Electronic signatures are legally recognized across European Union member states

However, some documents (like wills, adoption papers, or court orders) may require notarization or wet signatures. Check your specific requirements.

Frequently Asked Questions

Are electronic signatures legally binding?

Yes, electronic signatures are legally binding in most countries for most types of documents under laws like the ESIGN Act (USA) and eIDAS (EU). However, some documents require notarized or wet ink signatures.

Can I sign on my phone or tablet?

Absolutely! Our tool is fully optimized for touchscreen devices. You can draw your signature naturally with your finger on any smartphone or tablet.

What file formats are supported?

We only support PDF files for signing. If you have a Word doc, Excel spreadsheet, or image file, you'll need to convert it to PDF first.

Can I save my signature for future use?

Our tool doesn't store signatures for privacy reasons. However, you can:

  • Create a signature image file (PNG with transparent background)
  • Save it to your device
  • Upload it each time you need to sign a document

Can I add multiple signatures to one PDF?

Currently, you can add one signature per session. To add multiple signatures, download the signed PDF and then upload it again to add another signature.

What signature image format works best?

PNG files with transparent backgrounds work best. They blend seamlessly with the PDF background. JPEG works too but has a white background.

Can I change the signature color?

Drawn signatures are black, typed signatures use black italic text, and uploaded images retain their original colors. Black is standard for most official documents.

How do I create a transparent signature image?

Sign on white paper, scan or photograph it, then use a photo editor to remove the background and save as PNG with transparency enabled.

Is this tool really free?

Yes, completely free with no hidden fees, watermarks, or usage limits. Sign as many PDFs as you need.

Do I need to create an account?

No account needed! Simply upload your PDF, create your signature, and download the signed document. No registration, no email required.
