A letterhead mark, on your computer
Stamp a logo on a PDF
No files yet. Drop them above. They stay on your computer.
Stamp logo puts a PNG, JPG, or WebP on chosen pages: corners or center, with margin, scale, and opacity. Rotation stays at 0. First page only is the usual letterhead job and is the default. This is a focused sibling of Watermark, not a second DRAFT tile tool. For diagonal text, use Watermark PDF.
The logo is drawn with pdf-lib in the browser. Nothing is uploaded. You download a new PDF. Unlock encrypted files on your computer first. Close the tab and the working files are gone.

Stamp a logo without an online brand service
Watermark PDF is for tiled or diagonal words. This page is the quiet logo in the corner. Neither encrypts the file. Both run locally.
Need diagonal DRAFT text instead? Use Stamp DRAFT.
Questions
How is this different from Watermark PDF?
Watermark is for text or a tiled/diagonal stamp. Stamp logo is a single upright mark, often on the first page only.
Can I stamp only the first page?
Yes. First only is the default. Switch to All or tick pages if you need more.
Does a logo protect the file?
No. It is a picture on the page. Use Protect PDF for a password.
Will the original be overwritten?
No. You download a stamped copy.
Is the logo uploaded?
No. It is embedded locally. Close the tab and the working files are gone.
