Add image / stamp

Place an image on a PDF — a seal, a logo, a mark. Transparent PNGs stay transparent, so nothing lands inside a white rectangle.

No sign-up. Open it and use it.

How to do it

  1. Drop a PDF onto the page.
  2. Upload the image.
  3. Position it with the 3×3 grid or exact coordinates, set opacity and rotation, and download.

This one needs an upload, and is deleted afterwards

Browsers cannot do this calculation, so the file goes to our server. It is deleted automatically 60 minutes after the job finishes, and the working copy lives in a memory filesystem that is wiped whenever the server restarts.

We do not log file names and do not log file contents — that is a hard rule in our engineering standards, not a setting.

What it does — and what it doesn't

Common questions

My seal has a white box around it.
That image has no transparency. Save it as a transparent PNG and upload again.
Can it go on every page?
Yes — apply to the whole document.
How is it different from Signature stamp?
Signature stamp lets you draw on screen and always returns the "this is not a digital signature" note. Use this one for logos and mark images.
