Can the watermark be removed by the recipient?

It is drawn into the page content, so it is not a layer that can be toggled off in a reader. Someone determined enough could still edit it out with professional software, so treat a watermark as a clear signal of intent rather than a security control.

Should it go behind or in front of the text?

In front, at low opacity, is the usual choice — it stays visible even over images while leaving the text readable. Reduce opacity rather than moving it behind if it feels overpowering.

Can I use my logo instead of text?

Yes. A PNG with a transparent background works best, since the transparency is preserved and the logo will not sit in a white box.

Tiling repeats the watermark in a grid across each page instead of placing it once in the centre. It is harder to crop out, which suits documents you expect to be screenshotted.

What Watermark does

A watermark marks a document's status before it is circulated — DRAFT, CONFIDENTIAL, or a company logo. Set the text or pick an image, then adjust opacity, angle and whether it repeats across the page, and it is applied to every page at once.

How it works

The tool opens your document and draws the watermark directly into each page's content — the same layer the page's own text and graphics live in. Text watermarks are drawn with your chosen size, angle and opacity; image watermarks are embedded once and stamped onto every page, with PNG transparency preserved.

Because the mark becomes part of the page content rather than a separate annotation layer, it cannot be toggled off in a PDF reader, and it survives printing, re-saving and conversion. Tiling mode repeats the stamp in a grid so it covers the page rather than sitting once in the centre.

When to use it

A draft is circulating for comments and must not be mistaken for the final version.
A confidential document needs its status visible on every page, not just a cover sheet.
Company material should carry a logo before going to external recipients.
You want a document to be traceable — a per-recipient mark discourages quiet re-sharing.

Advantages and limitations

Advantages

Both text and image watermarks, with control over opacity, angle, size and tiling.
Applied to every page in one operation — no page-by-page stamping.
The mark is drawn into the page content, so it cannot be switched off in a reader.
Transparent PNGs are respected, so a logo does not arrive in a white box.
Tiling covers the whole page, which is much harder to crop or screenshot around.

Limitations

A watermark is a signal, not a security control — professional editing software can remove one with effort.
It cannot protect text from being copied; pair it with the Protect tool if you need to restrict opening.
Marks apply uniformly to all pages; per-page watermarks require splitting the document first.
Encrypted files must be unlocked before a watermark can be added.

Security and privacy

This tool runs entirely on your own device. The file you choose is read into your browser's memory, processed there by JavaScript, and returned to you as a download — no part of it is transmitted to our servers or anyone else's. When you close or reload the page, the browser discards that memory. We never see your document, cannot log it, and have nothing to delete afterwards. You can verify this yourself: open your browser's developer tools, switch to the Network tab, and process a file — you will see no request carrying your document.

Supported files

Input: one standard PDF file (.pdf), plus an optional PNG or JPG to use as an image watermark — PNG transparency is preserved. Encrypted PDFs must be unlocked first. Output: a .pdf with the watermark drawn into every page.

How to use Watermark, step by step

Upload the PDF you want to mark.
Choose a text watermark and type it, or pick an image (a transparent PNG works best).
Adjust opacity, rotation and size until the preview looks right, and enable tiling if you want the mark repeated across the page.
Click Apply to stamp every page on your device.
