Sign PDF with Image

Sign a PDF with an image of your signature

Add a signature image to your PDF, place it where it belongs, adjust the size if needed, and export the updated file in a lightweight signing flow.

Add image guide

Use your existing signature image

Start with a PNG or JPG of your signature. The workflow is built for practical document signing, not for complex signature design.

Resize before export

After placing the signature image, use the corner handles to make it smaller or larger until it fits the signature line.

Swap the signature cleanly

If you picked the wrong signature file, replace only the selected signature object instead of adding another image by mistake.

Trust note

A lightweight signing helper, not a compliance promise

This workflow is useful when a team needs to place a signature image into a PDF quickly. It helps with positioning, replacement, and export, but it should not be confused with regulated e-signature infrastructure.

For many practical internal documents, this is enough. For highly regulated or certificate-backed signing requirements, users should still rely on a dedicated e-sign solution.

Best for practical document workflows

Add a signature image, adjust it visually, and export the updated PDF without extra complexity.

FAQ

Can I sign a PDF by adding an image of my signature?

Yes. Choose your signature image file, place it on the page, resize it if needed, and export the updated PDF.

Can I replace the signature image later?

Yes. Select the signature image object first, then use Replace Selected to swap it without creating another object.

Does this page describe a handwritten signing workflow?

No. This workflow is for placing an existing image file of your signature inside the PDF, not for drawing a signature with a pen tool.
