What a drawn signature is
What you draw here is an image, placed where you choose on the page. It is the digital equivalent of initialling a printed document and scanning it again, and it covers the great majority of everyday uses: a purchase order, an authorisation, a form to send back.
French law and the eIDAS regulation recognise this form as a simple electronic signature. It is admissible, but if it is disputed, the person relying on it must establish that it belongs to the person it names — the image itself does not prove that.
What it does not do should be said plainly: it detects no change to the document. An amount under the signature can be altered with nothing to flag it, because the image and the text are two independent layers that do not watch each other.
Your signature never leaves your machine
The stroke is captured in the browser, embedded into the document on your device, and the signed file downloads straight away. Nothing is transmitted, and no server keeps the image of your signature — which, for a signature specifically, is not a detail.
You can go offline once the page has loaded: signing will still work.
Signature or seal: which one you need
The question arises as soon as the document commits someone. Two criteria settle it, and they are not the ones people expect.
If the point is to show agreement between people who know and trust each other, a drawn signature does the job. If a third party must be able to check later that the document has not moved — a client receiving an invoice, a body receiving a certificate — you need an electronic seal, which is computed from the content and fails on a single altered byte.
The two are not exclusive and often go together: the drawn signature shows who signed, the seal guarantees that what was signed has not changed since.
Common questions
Does this signature hold up legally?
It is a reproduced handwritten signature: worth what a scanned initial is worth, and fine for most everyday uses. For a signature whose integrity can be proven, see the electronic seal.
Are my files uploaded to the internet?
No. This tool runs entirely in your browser: the document is opened on your device, processed there, and never sent anywhere. You can even go offline once the page has loaded.
Is it free, and do I need an account?
Free and unlimited, with no account and no sign-up. This tool costs us nothing because it runs on your machine, so we have no reason to ration it.
