Add Watermark

Stamp text or an image watermark across every page of a PDF.

Coming soon

We're polishing this tool — read on to learn what it'll do, or try one of our working tools above.

Watermarking is how you mark a PDF as confidential, draft, or owned-by-someone before you share it. Converterzilla will let you place a text or image watermark across every page with control over rotation, opacity and position — all without uploading the document anywhere.

How Add Watermark will work once it ships

This tool isn't live yet — the steps below describe the planned experience, not something you can do today.

  1. Drop the PDF. Choose the document you want to watermark. We handle multi-page PDFs of any reasonable size.
  2. Set up your watermark. Type text or upload an image, then set rotation, opacity and which corner (or center) you want it placed in.
  3. Apply and download. Converterzilla stamps every page with your watermark and saves the result as a new PDF.

What Add Watermark will offer

Text or image

Choose between a text stamp like CONFIDENTIAL or upload your company logo as an overlay.

Adjustable opacity

From a faint background mark to a bold stamp — pick the visibility level that fits your use case.

Original stays untouched

We produce a new file. Your original PDF on disk is never modified.

Questions we expect about Add Watermark

Yes — select a page range to limit which pages receive the watermark.

Yes. Watermarks are baked into the PDF, so they appear in print and on screen exactly as configured.

Once burned in, a watermark can't be cleanly removed — it becomes part of each page's content.
