What does this tool do?

It places your signature onto any page of a PDF. Draw it with your mouse, trackpad or finger — or type your name in a script style — then click the exact spot on a page preview where the signature belongs, adjust its size, and download the signed document. The signature becomes part of the page, so it prints and displays everywhere.

How to sign a PDF

  • Add the PDF that needs signing.
  • Draw your signature on the pad (a finger works well on touch screens), or switch to the Type tab and enter your name.
  • Pick the page — the tool defaults to the last one, where signatures usually live — and click the preview where the signature should sit.
  • Fine-tune the size with the slider, then apply and download.

Drawn signature vs typed signature

A drawn signature looks like your handwriting because it is: the pad records your strokes and embeds them as a crisp transparent image. A typed signature uses a flowing script font — quicker, tidier, and common for initials or internal sign-offs. Both are accepted in everyday use: approvals, delivery notes, rental forms, permission slips, offer letters. Choose whichever the document's recipient expects.

An honest note on what this is

This tool creates a visual signature — the electronic equivalent of signing with a pen and photocopying. It is not a cryptographic digital signature and doesn't create an audit trail or tamper seal the way certificate-based signing platforms do. For most day-to-day paperwork a visual signature is exactly what's asked for; for high-stakes contracts where verification matters, use a certificate-based service.

Your signature stays on your device

Everything — the PDF, the page preview, your signature strokes — is processed in your browser. Nothing is uploaded, which matters twice here: once for the document, and once for your signature itself, which is not something you want stored on a stranger's server. Close the tab and every trace is gone.

Tips

  • Sign large on the pad and shrink with the slider — it comes out smoother than drawing small.
  • The click point becomes the centre of the signature; you can re-click to reposition before applying.

Frequently asked questions

Is this a legally binding signature?

In many everyday contexts a visual signature is accepted and enforceable, but rules vary by country and document type. For contracts requiring verified digital signatures, use a certificate-based platform; this tool is the electronic version of pen-on-paper.

Is my signature or document uploaded anywhere?

No. The drawing pad, the page preview and the final file all run in your browser. Neither the document nor your signature ever leaves your device.

Can I sign on a phone or tablet?

Yes — the pad responds to touch, and signing with a finger or stylus on a touch screen usually looks better than mouse drawing.

Can I place the signature anywhere on any page?

Yes. Choose the page (the last page is preselected), click the preview where the signature belongs, and adjust the size. You can re-click to move it before applying.

Does the signature print?

Yes — it's embedded into the page content as an image, so it appears in every viewer and on paper, exactly like the rest of the document.
