How do you add a digital signatuer. Is it possible?
Hello,
yes, with our online tool https://tools.pdf24.org/en/sign-pdf - there are two ways:
- Handwritten signature: After loading your PDF, the signature window opens. You can draw, type, upload or photograph your signature and then place it on the page.
- Digital signature with a certificate: Switch to Sign. Choose a signature with Choose signature… and click the page to place it, or tick Sign without a visible signature. Under Certificate you can choose:
- PDF24 certificate (self-signed): any later change to the document becomes detectable, but PDF programs cannot confirm who signed, as this is not a personal certificate.
- Sign in the browser (key stays local): with your own certificate file (.p12/.pfx) and its password. The certificate file and key do not leave your device.Optionally you can request a timestamp and enter name, reason and location. The document is signed when you click Save PDF.
Hello, a short update: the page https://tools.pdf24.org/en/sign-pdf now also explains in its FAQ how to sign a PDF digitally with a certificate: switch to Sign, then use the PDF24 certificate (self-signed) or your own .p12/.pfx file, optionally with a timestamp.
