Is my signature uploaded?

No. Your signature is drawn on a local canvas and embedded into the PDF in your browser.

Which page is signed?

Choose the page and position with the controls. The signature is stamped only on that page.

Is this legally binding?

It produces a visual signature. Legally binding e-signatures depend on your jurisdiction and may require a certificate-based provider.

Understanding sign pdf

This tool adds a visible signature: you draw with a mouse, trackpad or finger, or upload a signature image, then place it on the page. The result is what most day-to-day agreements need — a visual mark of assent on a document.

It is not a cryptographic digital signature. There is no certificate, no timestamp authority and no tamper-evidence. For qualified electronic signatures under eIDAS or comparable frameworks, use a certified provider.

Drawing happens on a canvas at device pixel ratio, so signatures stay smooth on high-DPI screens and phones, where a finger-drawn signature usually looks better than a mouse-drawn one.

When you would use it

—Signing a rental agreement or NDA sent as a PDF.
—Approving an internal expense form without printing it.
—Adding initials to each page of a contract annexe.
—Placing a scanned handwritten signature on a letter.

Practical tips

Sign with a finger on a phone or tablet; the result is far closer to your real signature than a mouse stroke.
Upload a transparent PNG if you already have a scanned signature — it blends into the page cleanly.
Flatten sensitive agreements by exporting to images afterwards if you want the signature not to be separable.

Troubleshooting

Nothing draws on the canvas: Make sure a PDF is loaded first — the drawing surface appears with the document preview.
The signature looks too big: Resize before placing; a signature roughly 4–6 cm wide matches a handwritten one on paper.
