How it works

Complete the job in three clear steps

Choose one PDF and an authorized signature image from your device.
Set the page and output options, then create a PDF containing the signature image.
Inspect the downloaded result before replacing or deleting the original document.

Important

Check the result before relying on it

Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.

Practical details

What this Lucaden tool does

The signature file is embedded as visible page content at the selected position. This is a visual signing aid, not a certificate-backed digital signature and not independent proof of identity.

The document stays in browser memory during processing. Lucaden creates a new output file and never modifies the source on your device.

Page and corner selection

Questions

About this tool

Is this a cryptographic digital signature?

No. It places an image and does not create a certificate-backed signature or validate signer identity.

Can I use a transparent signature?

Yes. A transparent PNG usually blends most naturally with the page.
