Sign PDF

Load a PDF, sign it, download it, and at no point does the document leave your computer. That is the whole pitch. You can draw your signature with a mouse or finger, or type your name and pick a script font, then place the signature on any page, resize it until it sits naturally on the line, and add a date beside it. The signed PDF downloads instantly with no signup, no watermark and no trial countdown.

The privacy point deserves a moment, because a lease, an employment contract or a settlement agreement is about the most sensitive file you handle all year. Most e-sign services upload your document to their servers as step one. This tool signs it in your browser using the pdf-lib library, so the contract never touches a server I or anyone else controls. I built it after being asked to create an account, verify my email and start a free trial just to put my name on a two-page PDF, an experience I assume you have shared. If your document is actually several files, my merge PDF tool combines them first.

How to use

1. Load your PDF by clicking the upload area or dragging the file in.
2. Draw your signature with your mouse, trackpad or finger, or type your name and choose a script style.
3. Click where the signature should go, on any page of the document.
4. Drag the corners to resize it until it sits naturally on the signature line.
5. Add a date line next to it if the document calls for one.
6. Download the signed PDF and send it back to whoever is waiting.

Why use our sign pdf?

Local processing is the reason this tool exists. Signing happens with JavaScript in your browser, the PDF is loaded into your device's memory, edited there and saved from there. You can load the page, go offline and still sign the document. For contracts, medical forms, financial paperwork and anything with your personal details on it, not transmitting the file anywhere is simply a better default than trusting a company's retention policy.

Speed is the second benefit. No account creation, no email verification, no uploading, no waiting for a link: from opening the tool to holding a signed PDF is realistically under a minute, which matters when a recruiter or landlord is waiting.

Both signature styles are here because people genuinely split on this. Drawing captures your actual signature, which looks right on formal documents. Typing in a script font gives a cleaner result for people who, like me, produce something resembling a seismograph reading when signing with a trackpad. If you want to design your signature once and reuse it everywhere, my signature maker is built exactly for that.

Now the honest part, which most e-sign marketing keeps quiet. What this tool produces is a signature image placed in the PDF, the electronic equivalent of ink on paper. Under the US ESIGN Act and similar laws in the UK, Canada and Australia, electronic signatures like this are broadly valid for most everyday agreements, and you can read the American law itself at the full text of the ESIGN Act. What this is not is a cryptographic digital certificate signature, the kind that embeds verified identity and tamper evidence, which some government filings and high-stakes transactions require. And none of this is legal advice; when the stakes are high, ask the receiving party what they accept.

Finally, there is no artificial scarcity. No three-documents-per-month cap, no premium tier hiding the useful features, no watermark advertising the tool on your contract.

Who is this tool for?

Job paperwork is the most common case: offer letters, contractor agreements, NDAs, tax forms. The employer emails a PDF, you sign here, date it and reply within minutes instead of hunting for a printer. Every remote worker and freelancer knows this loop, and I go through it myself with client agreements every month or two.

Renters sign leases and inspection reports this way constantly. Property managers in the US, UK and Australia increasingly email PDFs and are perfectly happy to receive a signed copy back, and doing it locally means your lease, with your name, address and income details, does not sit on a third-party server. If the agency sends five separate PDFs, merging them into one before signing keeps the paper trail tidy.

Small business owners countersign quotes, invoices and supplier agreements. A signed quote closes deals noticeably faster than an email that says "confirmed". I sign the odd collaboration agreement for this site the same way, and if you invoice clients, my invoice generator produces the PDF you will be signing.

Parents and everyday life fill the rest: school permission forms, sports club registrations, consent forms, insurance paperwork. These arrive as PDFs, need a signature and a date, and absolutely do not justify installing software or starting a subscription.
