Sign a PDF Online — Draw or Type Your Signature, Free
Sign a PDF in under a minute without printing, scanning, or creating an account. UtilHub's free PDF signer lets you draw your signature with a finger or mouse, type it in a handwriting-style font, or upload a photo of it, then place it on any page, resize it, and add the date or your initials. The signing happens entirely on your device: the PDF is opened and rewritten in your browser, so a contract, lease, or tax form is never uploaded to a server — unlike upload-based signers such as Smallpdf and PDF24, which keep files on their servers for an hour. There is no watermark and no daily limit, and the tool works the same on iPhone, Android, and desktop.

Frequently Asked Questions
How do I sign a PDF on my iPhone or Android phone?
Open this page in Safari or Chrome, tap "Choose PDF", and pick the file from Files, Mail, or Drive. Draw your signature with your finger, tap where it belongs, and download the signed copy. To skip the browser next time, install the tool: in Chrome tap "Install app"; in Safari tap Share, then "Add to Home Screen".
Can I sign a PDF without Adobe Acrobat?
Yes. You don't need Acrobat, Acrobat Reader, or any other software. The signer runs in your web browser, reads the PDF locally, and writes your signature into a new copy of the file. The signed PDF opens normally in Acrobat, Preview, Chrome, and every other PDF viewer, and no watermark is added.
Is my document uploaded when I sign it here?
No. The PDF is processed with JavaScript on your device and never sent to a server, so confidential contracts and forms stay private. You can verify this: open your PDF, turn off Wi-Fi, then place your signature and download the signed copy — it still works. Upload-based signers keep a copy of your file on their servers, even if only temporarily.
Is an electronic signature on a PDF legally binding?
In most countries, yes. Laws such as the US ESIGN Act and the EU's eIDAS regulation recognize electronic signatures for most everyday agreements, as long as the signer intends to sign. Some documents — certain wills, notarized forms, or government filings — require a certificate-based or qualified signature instead, so check what the recipient accepts.
What is the difference between an electronic and a digital signature?
An electronic signature is any mark that shows you agree — a drawn, typed, or scanned signature placed on the page, which is what this tool creates. A digital signature is a cryptographic, certificate-based seal, for example from a CAC card or a qualified provider, that proves the file was not changed after signing. This tool does not apply certificate-based signatures.
