How to sign a PDF
- 1
Add the document
Drop your PDF in. Every page renders so you can scroll to the signature line, however deep in the document it is.
- 2
Create your signature
Type your name and pick a script style, or draw with your finger or mouse — drawing on a phone usually looks most natural. The signature is created as an image with a transparent background so it sits cleanly on the page.
- 3
Place it precisely
Click where the signature belongs. Drag to adjust; it lands exactly where you put it, on the page you put it, at a sensible size relative to the page.

Download the signed copy
The signature is drawn into the PDF itself, not layered on top — it survives printing, forwarding and every reader. Your original file is unchanged.
Is a signature added this way legally valid?
In most jurisdictions, for most everyday documents, yes. Laws like the US E-SIGN Act, eIDAS in the EU and the IT Act in India recognise electronic signatures broadly — what generally matters is intent to sign and consent to do business electronically, not the technology used. An image of your signature placed by you, with intent, on a lease, invoice, NDA or permission slip is how millions of documents get signed every day.
Where this is not enough: documents requiring notarisation, some property and court filings, and workflows that demand a certificate-backed digital signature with cryptographic identity verification (a qualified signature under eIDAS, or DSC-based signing in India). If your counterparty specifies that kind of signature, they need a certificate authority process, not a drawing. For everything else, this does the job — but this is general information, not legal advice for your specific document.
Why signing is the worst thing to upload
A signature service that processes files on its servers ends up holding two things at once: your signature image and the documents you sign. That combination is precisely what identity fraud needs. Even with an honest operator, it's an unnecessary concentration of risk — and the documents people sign (contracts, offers, financial agreements) are among their most sensitive.
Here, the signature is generated on your device and drawn into the PDF on your device. Neither ever exists anywhere else. Load the page, disconnect from the internet, and sign — it works, because nothing about signing a document ever needed a server.
Frequently asked questions
Is typing my name as a signature legally binding?
Broadly, yes — electronic signature laws in the US, EU, India and most jurisdictions focus on intent rather than appearance, and a typed or drawn signature applied by you generally qualifies for everyday agreements. Notarised documents and workflows requiring certificate-backed digital signatures are the exceptions. Treat this as general information rather than advice on a specific contract.
Should I draw or type my signature?
Drawing on a touchscreen most resembles your pen signature and reads as more personal. Typing in a script style is faster and looks tidy. Legally the distinction rarely matters; pick what the document's tone calls for.
Can the signature be moved or removed by the recipient?
Once you download, the signature is flattened into the page content like ink — it isn't a floating annotation someone can drag away or delete in a reader. Editing it out would mean editing the document itself.
Can I sign on my phone?
Yes, and drawing with a finger on a phone usually produces the most natural-looking signature of any method. The tool works in mobile Safari and Chrome with nothing to install.
Is my document or signature uploaded?
No. Both stay on your device — the signature image is generated locally and drawn into the PDF locally. That combination (your documents plus your signature) is exactly what you don't want stored on someone's server.
Can I sign a password-protected PDF?
Remove the password first with the Unlock tool, sign, then re-protect the signed copy with the Protect tool if it needs to stay locked.
