mousePDFSign a PDF — without an account, without uploading
Draw your signature with your mouse or finger, type it as text, or insert one — and place it anywhere in the document.
Three simple steps
Open a PDF
Load the document you want to sign.
Create a signature
Draw your signature or type it (handwriting, serif, or sans-serif style).
Place it & export
Drag the signature to the right spot, then save the signed PDF.
Draw it or type it
Your signature can be drawn freely with a mouse, finger, or stylus — or entered as text if you'd rather not draw. Typed signatures come in three styles: handwriting, serif, or sans-serif.
If your document is a form without real input fields, you can first place the text with the form filling feature, then sign it.
The signature is embedded into the page as a transparent image and can be placed as many times as you need at different spots — useful for multi-page contracts with several signature fields.
When to sign digitally?
Rental agreement without a printer. Your new lease arrives as a PDF and you don't have a printer handy. Just draw your signature in the browser and drop it on the last page.
Filling out and signing forms. Government forms and applications often need a signature at the end. With mousePDF you type in the fields and place your signature below — all in one go.
Multi-page contracts. Some contracts require initials on several pages. Create your signature once and place it wherever it's needed throughout the document.
What this signature is — and what it isn't
Your signature is placed on the page as an image. It looks like a signature on paper and serves the same purpose: it shows that you signed the document.
It is not a cryptographic signature. The document gets no certificate, and no PDF viewer will show a green tick reading “signature valid”. Anyone who needs a qualified electronic signature — required for certain contracts and for dealings with public authorities — needs a trust service provider that verifies identity. mousePDF cannot do that, and we will not pretend otherwise.
Why not? A qualified signature requires that someone has verified your identity and holds a private key on your behalf. That is precisely a service with a server and an account — the opposite of what mousePDF is built for. For the far larger part of everyday life, an image signature is enough: delivery notes, registrations, consent forms, internal approvals.
What an image signature cannot do
An image sitting on a PDF page can be extracted again with the right tools — and in theory placed under a different document. There is nothing mousePDF can do about that, and no other PDF tool either: using a signature as an image means accepting that risk. The same is true of a scanned paper signature, which any photocopier reproduces.
If that risk is too great, only a different kind of signature helps. A qualified electronic signature binds the document cryptographically to a verified identity — it cannot be lifted off, because it is not a picture. That requires a trust service provider, as described above.
What helps in everyday practice: do not leave the signed PDF lying around openly. To stop unauthorised people opening it at all, you can set a PDF password.
Frequently asked questions
Is a signature created this way legally equivalent to a real digital signature? +
No — mousePDF inserts a visual image of your signature; this isn't a qualified electronic signature under eIDAS. It's typically sufficient for informal agreement, internal approvals, or quickly signing a scanned form.
Can I sign in several places in the document? +
Yes, the same or a new signature can be placed as many times as you like, including on different pages.
Is my signature stored anywhere? +
No, it only exists in your browser's memory for as long as the page stays open.
Can I save my signature for later use? +
Not across sessions — the signature exists only in your browser's memory while the page is open. Once you close or reload the page, it's gone. That's intentional: we don't store your signature anywhere.
Is my signature legally binding? +
For many everyday cases a simple electronic signature is enough, and that is what this is. Where a qualified electronic signature is required it will not do — that needs a trust service provider who verifies your identity. If in doubt, ask the other side which form is required and accepted.
Is my signature stored anywhere? +
No. It is created in your browser and stays there. There is no upload, no account and nothing filed on a server — your personal signature is one of the last things you should hand over to someone else's service.
Can I place the same signature on several pages? +
Yes. Once drawn, it can be placed, moved and resized as often as you like before you export.
