QUICK ANSWER

Watermark selected PDF pages with text or an image

Watermark PDF adds a visible text or image mark to selected PDF pages. The current controls cover single or tiled layout, a nine-position grid, tile density, size, opacity, rotation, color, layer order and page selection. Use a short status label for review copies, or choose a transparent image when the mark must match an existing brand or workflow. The result is generated locally in the browser.

Label a PDF without changing its text

Review dense pages so the watermark stays secondary to the content.

BEFOREBefore: a clean copy with no distribution label.

AFTERAfter: a readable text or image watermark with controlled opacity and range.

HOW TO USE

How to watermark a PDF

Start with a low-opacity preview, then increase contrast only as much as needed to keep the document readable.

Choose a PDF and wait for the first page preview.
Select Text or Image. For an image watermark, choose a PNG, JPEG or WebP file.
Choose Single for one mark or Tiled for repeated marks, then set the position and density.
Adjust size, opacity, rotation, color and whether the mark sits over or behind content.
Choose all pages, a range, odd, even or excluded pages.
Set a file name, apply the watermark and inspect pages inside and outside the selected range.

PARAMETER GUIDE

Watermark settings explained

A watermark should identify status or ownership without hiding totals, signatures, body text, QR codes or page instructions.

Watermark settings explained
Setting	Effect	When to choose it
Text	Renders a typed label	DRAFT, CONFIDENTIAL or internal status
Image	Places an uploaded image	Logo, approved seal or branded mark
Single	One mark on each selected page	A clear but restrained status mark
Tiled	Repeats the mark across the page	Broad visual notice or review copy
Over content	Keeps the mark visible above page content	When the label must be obvious
Behind content	Places the mark below page content	When readability is more important than prominence

EXAMPLES

Watermark examples

Draft review: use a short text label, moderate opacity and a single central or corner position.
Confidential circulation: use a repeated light mark, but keep account numbers and signatures readable.
Branding: use a transparent image and inspect its edges on both white and colored page backgrounds.

LOCAL PROCESSING

Local processing and responsible use

The PDF and selected watermark image are read by browser code and the new file is generated locally. A visible watermark is an ordinary page mark, not proof of identity, notarization, certificate signing or tamper resistance. Use an approved signing process when your organization needs those properties.

LIMITATIONS

Limitations and export checks

A watermark does not cryptographically protect a PDF or prove who approved it.
Behind-content marks can become difficult to see on busy backgrounds.
Tiled marks can cover important text if size or opacity is too high.
Password-protected, damaged or memory-heavy PDFs may fail to render or export.

TROUBLESHOOTING

Watermark troubleshooting

If the mark hides text, reduce size or opacity, change the position or use Behind content.
If an image has a visible box, use a transparent PNG or remove the background before uploading.
If only some pages should be marked, verify the selected range and inspect the first page just outside it.
If the result looks different from the preview, open the downloaded PDF and check the same page at 100% zoom.
