Steps for this task

Clean up a signature photo and place it in a PDF

  1. 01

    Prepare the signature photo

    Photograph the signature on bright paper and keep it as one PNG or JPEG. A dark or complex background may not separate cleanly.

  2. 02

    Clean the signature

    In Remove a signature background, adjust crop, rotation, and removal strength while checking that the ink remains. Save a transparent signature PNG.

  3. 03

    Place it on the PDF

    In Stamp a PDF, choose one unencrypted PDF and the signature PNG, then adjust page, position, size, and opacity.

  4. 04

    Check the new PDF

    Apply it to the current or all pages, save a new PDF, and open it once more to check the placement. An image is not a legal signature by itself.

Frequently asked questions

Frequently asked questions

Can every photo background be removed?

The cleanup targets bright paper. It does not provide AI separation for dark or complex photo backgrounds, so review the result before saving.

Will the source PDF change?

No. The tool saves a new PDF and leaves the source unchanged. Encrypted or damaged PDFs are not supported.

Is the result a legally recognized e-signature?

Placing an image on a PDF does not prove identity or guarantee a legal or certificate-based electronic signature. Check the receiving organization’s requirements.
