About image watermark pdf
Stamp a logo, signature image, or seal as a watermark on every page of a PDF. It sits in the pdf & office shelf alongside 83 other pdf & office tools, needs no account, and keeps the same behaviour whether you open it here or call it through the REST API.
It accepts PDF, PNG, JPG and gives back PDF. It is built for files larger than the usual upload ceiling. The work happens on our servers, and the upload is encrypted per file and deleted an hour later — 24 hours if you are signed in. The same operation is available programmatically at POST /v1/pdf/image-watermark.
Image Watermark PDF questions
Where does Image Watermark PDF process my file?
On our own servers. This tool needs more than a browser tab can provide, so the file is uploaded over TLS, processed on our infrastructure — no third-party processing APIs are in the path — and both the input and the result are deleted within an hour.
Can I run Image Watermark PDF on several files at once?
Yes — select or drop as many as you need and they are handled together.
Do I need an account to use Image Watermark PDF?
No. Image Watermark PDF works without signing in, and that is not a trial — it is how the free tier works. An account only matters for things that need one to exist at all: larger server jobs against your quota, API keys, saved workflows and billing.
Can I run Image Watermark PDF from my own code?
Yes. Every tool on the site is reachable from the REST API with the same slug — `pdf-image-watermark` — and the same options as this page, so anything you can do here you can automate against your own files.
