This tool lets you draw a signature with a mouse, trackpad or finger and place it anywhere on a page of your PDF — replacing the print, sign, scan cycle that most people still go through for a single line on a single page.
The signature you draw is trimmed to its own bounding box, so surrounding blank space on the drawing pad does not become an invisible rectangle on the page. It is embedded as a transparent PNG, which means the paper texture and shading of the underlying page show through exactly as they would if you had signed the printout. Its aspect ratio is preserved inside the box you place, so the signature is never stretched.
Your signature never leaves the browser. It is drawn on a local canvas, embedded into the document in memory, and downloaded — there is no account, no signature stored on a server, and no copy of your document anywhere.
-signed suffix; your original is untouched.The distinction matters and is worth being precise about. What this tool produces is a visible image of your signature placed on the page, the digital equivalent of signing a printout. It is the appropriate and accepted form for the vast majority of everyday paperwork: internal approvals, delivery notes, rental agreements, consent forms, school letters.
A cryptographic digital signature is something else entirely. It binds the document to a certificate issued by a trusted authority, proves mathematically that not a byte has changed since signing, and identifies the signer. That requires a certificate you have obtained and installed, and software such as Adobe Acrobat that can apply it. If a contract explicitly demands a qualified electronic signature, you need that route, not this one.
In many jurisdictions a signature applied electronically with intent to sign is valid for ordinary agreements, and this is the same category as signing a printout. Anything requiring a qualified or certificate-based electronic signature needs dedicated software instead. Check what the specific document demands.
One signature is placed per pass. To sign several pages, apply the signature, then load the resulting file again and sign the next page.
No. It exists only on a canvas in your browser tab for the length of the session. Nothing is saved, uploaded or associated with an account.
No. It is embedded as a transparent PNG trimmed to its own bounding box, so the page shows through around the strokes.
Not on this tool. As a workaround, photograph your signature on white paper, remove the background in an image editor, and place it with Add PDF Pages or an image editor of your choice.
No. The existing pages are preserved as they are; only the signature image is added to the page you chose.
