Electronic signatures and when they are accepted
A drawn signature placed on a PDF is a simple electronic signature. Many countries accept these for everyday agreements, such as rental contracts, job offers, school forms and invoices, as long as both sides agree to sign electronically.
Some documents still need more: wills, property deeds and some government forms may require a wet-ink signature, a witness or a certified digital signature. Check what the other party needs. For a clean result, sign on the final version of the document, then add a watermark such as COPY to any duplicates you share, or merge the signed pages with supporting documents.

Frequently asked questions
Is my file uploaded to a server?
No. Everything happens inside your own browser, so the file never leaves your device. That makes it safe for contracts, statements, ID documents and anything else private. Once the page has loaded, the tool even works offline.
Is a drawn signature legally valid?
In many countries an electronic signature like this is accepted for everyday agreements, but some documents, such as wills or property deeds, need special formalities. Check what the other party or the law requires.
Is this a digital certificate signature?
No. It places an image of your signature on the page. It does not add a cryptographic certificate.
How do I sign on a phone?
Draw in the signature box with your finger, then tap the page where it should go.
Can I use a scanned signature?
Yes. Choose Or upload an image and pick a PNG or JPG of your signature. A PNG with a transparent background looks best.
Can I sign several pages?
Tick Put the signature on every page to add it to all pages in the same position.
Is my signature saved anywhere?
No. It exists only in this browser tab and disappears when you close it.
Does it work with password-protected PDFs?
No. Remove the password first, then open the file here.
Can I move the signature after placing it?
Yes. Just click somewhere else on the page before you download.
Can I sign a PDF on my phone?
Yes. Draw your signature with your finger, tap where it should go on the page and download the signed PDF.
How this tool works. These PDF tools run entirely in your browser using two widely used open-source libraries: PDF.js, the PDF engine built into Firefox, to read and render pages, and pdf-lib to create and edit files. Each tool is tested with typed documents, phone scans and photo-heavy files before it goes live, and nothing you open is sent to a server.
