Click "Add to page", then drag the signature where it belongs. Use the corner to resize.
Signing a document should not mean printing it, signing with a pen, scanning it back, and emailing it — nor uploading it to a service that keeps a copy. Draw your signature with a finger or mouse, type it in a handwriting style, or drop in a photo of your real signature, then position it on the page. The whole thing happens in your browser, so the contract you are signing never leaves your device.

Why use this tool
Because the print-sign-scan-email loop is slow and produces an ugly document, and the online alternatives ask you to upload a contract you have not even signed yet.
Frequently asked questions
Is this a legally valid signature?
It adds a visible signature image to the document, which is what most everyday agreements, forms and letters need. It is not a cryptographic digital signature (a DSC) of the kind some legal and government processes require — that involves a certificate that proves identity and detects tampering. For ordinary sign-and-return documents, a visible signature is what is expected; where a DSC is specifically required, use the software your certifying authority provides.
Does my file or password get uploaded?
Neither. The PDF and any password you type are handled entirely inside your browser tab by qpdf compiled to WebAssembly. Nothing is sent over the network — you can confirm this in your browser's Network tab, where the engine loads once and then nothing uploads. For a password-protected bank statement or ID document, this is the whole point: the one file you must never hand to a website is exactly the kind these tools handle without one.
Can I reuse my signature?
Within a session, yes — once created, place it on as many pages as you need. For privacy, your signature is not saved between visits: it lives only in the current page and is gone when you close the tab. Uploading a photo of your signature each time keeps it consistent.
Will the rest of the document stay intact?
Yes. Unlike redaction, signing does not flatten the page — your signature is drawn on top of the existing page, and all the original text stays selectable and searchable. Only the signature is added.
