Watermark PDF

Stamp a text watermark - like DRAFT or CONFIDENTIAL - diagonally across every page of a PDF, so it's clear at a glance how the document should be treated.

When to use Watermark PDF

For marking a document's status or ownership so it survives being forwarded, printed or screenshotted - drafts that should not be mistaken for final, or a file you are sharing but do not want reused. A watermark deters casual misuse; it is not security. If the content must stay unreadable without permission, use Protect PDF.

Troubleshooting

The watermark is hard to read over dense pages

Shorter text reads better. A single word like DRAFT or CONFIDENTIAL is far clearer than a sentence.

You need to remove a watermark later

Not possible - it is part of the page content now. Always keep the unwatermarked original.

The upload is rejected before anything happens

The file is over the 20 MB cap. Compress it first, or split a long PDF into smaller files and process them separately.

No - it's drawn semi-transparently, so your content stays readable underneath.
