PDF Signing Tool FAQ
Is this PDF signing tool free to use?
Yes, our PDF signing tool is completely free to use with no hidden costs, no signup required, and no limitations on the number of documents you can sign.
Are electronic signatures legally binding?
Yes, electronic signatures are legally binding in most countries under laws like ESIGN Act (USA), UETA, and eIDAS (EU). Our tool creates valid electronic signatures suitable for contracts, agreements, and legal documents.
Is my PDF document secure when using this tool?
Absolutely. Your PDF files are processed entirely in your browser and never uploaded to any server. Your documents remain private and secure on your device at all times.
Can I sign a PDF on my phone?
Yes. The signer works in the browser on iPhone, Android phones and tablets. Draw your signature with your finger or type it, tap the page where it should go, drag it into place and download the signed PDF. There is nothing to install.
Can I add initials, the date or text to a PDF?
Yes. Besides your full signature you can place your initials, a date in the format you choose and any text, such as your printed name or job title. Each one can be moved, resized, rotated or copied to every page, for example to initial each page of a contract.
What is the difference between an electronic signature and a digital signature?
An electronic signature is any mark of agreement on a document, such as a typed name or an image of your handwritten signature. That is what this tool adds to your PDF. A digital signature is a certificate-based electronic signature that cryptographically seals the file and identifies the signer; it needs a certificate from a trust provider, which this tool does not issue. Most everyday agreements accept a simple electronic signature, but some documents, such as wills, notarized papers or certain government forms, need a specific method. If you are unsure, ask whoever requested your signature. This is general information, not legal advice.
