It is an electronic signature, the same kind you make by signing a printout and scanning it, and in most places for most agreements that is accepted. What it is NOT is a digital signature: there is no certificate proving who signed, and nothing that would show the document had been altered afterwards. If a counterparty has asked specifically for a digital or certificate-based signature, this is not that, and any tool telling you otherwise is selling you an assurance it cannot deliver. ### Where does my signature go after I draw it? Nowhere. It is drawn on a canvas in your browser, trimmed, and written straight into the PDF in memory. It is not stored, not sent anywhere, and gone when you close the tab. That matters more here than on most tools: a signature is the one thing you should be least willing to upload to a stranger. ### Can I sign more than one page? Yes. Move between pages and click where the signature goes on each. The image itself is embedded once no matter how many pages carry it, so initialling a long contract does not multiply the file size. ### Can I use a photo of my real signature instead of drawing one? Yes. A PNG with a transparent background works best. A JPG will carry its white background as a visible box, so if you photographed a signature on paper, remove the background first or draw it here instead. ### Does signing change anything else in the document? No. The signature is appended to the page's content, not merged into it, so nothing already on the page is re-rendered or recompressed. Page size, rotation, bookmarks and form fields all survive. ### Can it sign a password-protected PDF? Not while it is locked. Remove the password first with the unlock tool, which needs the password you already know, then sign the result. ## Related tools - [Unlock PDF and password protect PDF](https://filetity.com/protect-pdf): Remove PDF password protection when you know the password, or add AES-256 encryption. - [Watermark PDF](https://filetity.com/watermark-pdf): Stamp text like DRAFT or CONFIDENTIAL across the pages of a PDF. - [Fill PDF form](https://filetity.com/fill-pdf-form): Fill in a PDF form online, and lock the values if you want to. - [Redact PDF](https://filetity.com/redact-pdf): Black out parts of a PDF so the text underneath is actually removed.
