Choose a PDF and an image (PNG or JPG — a logo works perfectly), set its position, size and opacity, then download the stamped copy. Runs fully in your browser — nothing is uploaded, and your original file is never changed.
Put your logo on every page of a document in one pass — positioned, sized and faded exactly how you set it.

Stamp an image — a logo, a signature graphic, a photo — onto a PDF: nine positions, adjustable width and opacity, on every page, the first page or the last.
A photographer delivers a 12-page proof gallery: her logo at 18% width, 55% opacity, bottom-right of every page. One pass stamps the whole set consistently — the same size, the same corner, the same fade on all twelve pages.
The image is embedded into the document once and drawn onto each chosen page at the position you picked, computed from that page’s own width and height, so mixed page sizes stamp proportionally. Opacity is written as a real PDF transparency value. Nothing is re-rendered: the underlying pages keep their text, vectors and quality.
Yes — upload a PNG with transparency and the see-through areas stay see-through on the page. JPG has no transparency, so its background stamps as a solid rectangle.
Watermark PDF stamps text, tiled or centred, with watermark-style controls. This tool stamps an image file — logos, photos, signature graphics — with page-scope and margin controls.
One image per run, on every page, the first or the last. For a one-off placement on a specific page with click positioning, use Edit PDF.
The image is embedded at its original resolution. A 4 MB photo stamps a 4 MB payload into the file; shrinking the photo first keeps the PDF lean, and the on-page display size is set by the width slider regardless.
No — the PDF and the image are combined in your browser and the result downloads directly.
