Frequently asked questions

Where do I choose the logo?

Select the document first, then use the watermark image control for your logo. Both files stay on this device.

How is the logo sized?

Its width is a percentage of the displayed page width, constrained to fit the page while retaining its proportions.

Can I use a transparent logo?

Yes. A transparent PNG is suitable; the watermark also has an opacity control.

Does adding a logo lock the PDF?

No. The tool adds an image but does not apply encryption, permissions, or editing restrictions.
