Useful PDF controls

Add a watermark across the pages that matter

A PDF watermark can mark ownership, review status, confidentiality, or a draft version without changing the original file. The editor keeps the common controls close to the preview so you can create a clear result before downloading a copy.

  • Use text or a logo

    Type a short label such as Confidential, Draft, Approved, a copyright notice, or a brand name. You can also use a PNG or JPG logo when a visual mark fits the document better than text.

  • Choose the right pages

    Apply the watermark to every page, the first page only, or a custom set such as 1, 3-5. This is useful when a cover needs a visible status label but appendices or signed pages should remain cleaner.

  • Balance visibility and readability

    Control opacity, size, rotation, and placement so the watermark is clear without making the document hard to read. Repeating the mark across a page is available for stronger draft or proof protection.

  • Keep the PDF local

    The selected PDF is opened in the browser, watermarked in the browser, and downloaded as a new file. Apply Watermark does not create an upload queue, account library, or remote document copy.

Four-step browser workflow

How to add watermark to PDF online

The workflow stays focused: select the PDF, choose the mark, pick pages, and download a watermarked copy.

  1. Select a PDF from your device

    Choose the document you want to watermark. Keep the untouched original in its normal folder, especially when the file is part of a contract, client proof, or archive.

  2. Create the watermark

    Enter text or choose a PNG/JPG logo, then adjust its color, size, opacity, rotation, and placement. The sample page gives a quick sense of how the mark will read.

  3. Choose all or selected pages

    Watermark every page for consistent protection, or target only the pages that need the mark. Custom page ranges are counted from page 1.

  4. Download a new PDF

    The finished document downloads as a separate PDF. Open it once before sharing to confirm spelling, placement, page coverage, and readability.

Useful answers

Questions people ask before they begin

These short answers cover the practical details that matter most before you use the page.

Does the PDF get uploaded?

No. The selected PDF is read and modified in the browser. Apply Watermark does not receive the document, create a cloud copy, or require an account.

Can I watermark every page at once?

Yes. Choose all pages to add the same watermark throughout the PDF, or choose a custom page range when only certain pages need the mark.

Can I use an image logo?

Yes. PDF logo watermarks support PNG and JPG files. A transparent PNG usually gives the cleanest result on top of existing page content.

Will the original PDF be changed?

No. The editor creates a new watermarked PDF download. Your original file remains unchanged on your device.
