Is this legally valid?

A visual signature on a document is what most everyday signing means. It does not include cryptographic certificate-based signing (Adobe-style digital IDs) — where a counterparty requires that specific standard, this tool is not it.

A normal PDF with the signature flattened into the page — it looks and prints the same in every PDF reader, and the signature cannot be dragged off like an annotation.

Can I sign multiple pages at once?

Yes — choose "Every page" to place the same signature on all pages, or "Current page" for a single specific page.

Sign a PDF Online — Free, Private, No Upload

Signing a lease, an NDA, or a freelance contract should not mean uploading that contract to a signing service's servers, creating an account, or paying a monthly fee for three signatures a year. This tool draws your signature into the PDF entirely inside your browser: draw it with your mouse or finger, type your name in a handwriting font, or upload a photo of your signature — then drag it exactly where it belongs and download.

How it works: 1) Drop your PDF — it renders locally and never leaves the device. 2) Create the signature once (draw / type / upload). 3) Drag it into position on the page preview, choose the target — current page, last page, or every page — and download the signed document.

The signature is flattened into the page as a regular image, so it opens and prints correctly in every PDF reader, with no watermark and no account. Being honest about what this is: it places your signature visually — it does not apply cryptographic (PKI/digital ID) verification, which is what banks and some legal workflows require.
