About Signing PDFs Online
An electronic signature on a PDF is a digital copy of your handwritten signature. PDFNoob embeds it into the document. The US ESIGN Act of 2000, UETA, and the EU eIDAS regulation give e-signatures the same legal weight as ink. This covers most agreements: contracts, NDAs, employment offers, vendor agreements, and consent forms. A few high-stakes documents still need wet ink. These include wills, some real-estate filings, and court orders. Check local rules if you are unsure.
PDFNoob makes a standard electronic signature. The tool flattens an image of your drawn, typed, or uploaded signature into the PDF page content. This works for everyday business and personal use. For a cryptographic digital signature with a trust service provider certificate, use a certificate-based signing service. That is a different product class than free online signers.
Draw, Type, or Upload: Which Should You Pick?
Drawing your signature with a finger, stylus, or mouse looks most like a paper signature. Typing your name renders it in a cursive font. It is the fastest option when you just need attribution. Uploading a scanned image gives a consistent look across documents over time. A PNG with a transparent background works best.
What About the Rest of the Form?
Most agreements need a printed name, a date, and sometimes initials on every page. PDFNoob lets you add text boxes for each. Place them where the form asks. Type the value. They flatten into the final PDF next to your signature.

Yes. Sign and download the file. Re-upload it and add a second signature in a new spot. Each signature flattens into the PDF before download. The final file shows all signatures in order.
Does the Signed PDF Have a Watermark?
No. PDFNoob never brands your signed document. The output looks like the input plus your signature.
Can I Sign a Password-Protected PDF?
Not directly. Use the Unlock PDF tool with the password to remove protection first. Then sign the unlocked file. We do this for security. We never want to be misused to bypass document protection.
