Legal & privacy

Is this signature legally valid?

Signing a PDF in your browser produces a simple electronic signature. For the documents most people actually sign, that is exactly what the law expects.

United States

ESIGN Act (2000) & UETA

European Union

eIDAS (2014)

United Kingdom

Electronic Communications Act 2000

Worldwide

Recognised in most jurisdictions

Where a signature may not be enough. A small number of documents still require a handwritten signature or notarisation — wills and testamentary documents, some court filings, and certain government or immigration forms. If you are signing something in that category, check the receiving party’s requirements first. For contracts, agreements, invoices, NDAs, offer letters, leases, and everyday paperwork, a simple electronic signature is the standard.

FAQ

Sign PDF online: frequently asked questions

How do I sign a PDF without printing it?

Open the PDF in the signing tool, create or select your signature, drag it into position on the page and resize it, then download the finished file. Nothing needs to be printed, scanned or installed, and the document is never uploaded.

Is it safe to sign a PDF online?

It is safe with a tool that processes the file locally. This one reads, modifies and writes the PDF in your browser, so the document never reaches a server. You can confirm that yourself by opening your browser's network tab and watching for a request carrying the file — there is none.

Can I sign a PDF on my phone or tablet?

Yes. The tool works in a mobile browser and supports touch input, so you can draw your signature with a finger or stylus, place it on the page and save the signed PDF directly to your device.

Does the signed PDF have a watermark?

No. The downloaded PDF is the document with your signature applied and nothing else added — no watermark, no footer, no branding.

Is an electronically signed PDF legally binding?

In the ordinary case, yes. ESIGN and the state UETA provide that a signature may not be denied legal effect solely because it is electronic. What matters is intent to sign, attribution to the signer, and the ability for each party to retain and reproduce the record.

Can more than one person sign the same PDF?

Not in a single coordinated workflow — this tool signs a document once, locally. If several parties need to sign in sequence, or you need reminders and a completion certificate, use a platform built for sending documents and tracking signatures.

Why Use an Online PDF Signing Tool?

Signing a PDF document used to require printing it out, signing with a pen, scanning it back in, and emailing the result. That process wastes paper, takes several minutes per document, and often produces blurry scans. An online PDF signing tool lets you complete the entire process in your browser — upload, sign, download — without ever touching a printer.

When should you sign a PDF online?

Online PDF signing is ideal for any document that requires your signature but doesn't need notarization or witness signatures. Common use cases include:

Employment contracts and offer letters: Most employers accept digitally signed PDFs for onboarding paperwork.
Rental leases and housing agreements: Landlords and property managers routinely accept e-signed leases.
Non-disclosure agreements (NDAs): Standard NDAs between businesses can be signed electronically.
Tax forms (W-9, W-8BEN): The IRS accepts electronic signatures on most tax documents.
Client approvals and project sign-offs: Freelancers and agencies use e-signatures to close projects quickly.
School and university forms: Enrollment applications, scholarship forms, and consent documents.

Is online PDF signing legally valid?

In most countries, yes. The United States ESIGN Act (2000) and the EU's eIDAS regulation both recognize electronic signatures as legally binding for the vast majority of commercial and personal documents. A signature created by drawing or typing in a browser-based tool qualifies as a simple electronic signature (SES) under these frameworks, which is sufficient for contracts, agreements, forms, and most other paperwork.

The key legal requirement is that all parties must consent to conducting the transaction electronically. As long as this consent exists, your e-signed document carries the same weight as an ink-signed version.

How to get the best result when signing PDFs

For the most professional-looking result: create your signature first using our signature generator, then upload it when signing the PDF. This gives you full control over font style, ink color, and stroke width before you place it on the document. Position your signature on or just above the signature line, resize it to match the surrounding text, and rotate it slightly if the line is angled.
