Add Watermark

Add Watermark

Stamp a watermark across every page of a PDF.

Add a text or image watermark – DRAFT, CONFIDENTIAL, a company logo – to every page or just a range. Control opacity, rotation, position and layering (behind or on top of content).

Files auto-deleted within 1 hour · no signup for basic use

How it works

Four calm steps.

  1. 01

    Drop your file

    Drag the PDF you want watermarked onto the upload card, or click to pick it from your device. You can also paste a link to a file hosted online.

  2. 02

    Design the watermark

    Type text or upload a PNG. Tune opacity, rotation, position and font. Live preview shows the result.

  3. 03

    Preview before you commit

    Check the outcome in the browser first. Reorder, remove, or re-run with different settings – nothing is final until you press download.

  4. 04

    Download the result

    Save the watermarked PDF to your device, share a temporary link, or send it straight to Google Drive or Dropbox. Files are wiped from our servers within one hour.

Why Add Watermark

Built to be the last add watermark tool you try.

Behind or in front

Layer under content for subtle branding, or over for hard-to-remove stamps like 'DRAFT'.

Batch-friendly

Apply the same watermark to dozens of files at once with a Pro plan.

Private by default

Uploads travel over TLS, files are encrypted at rest, and every trace is deleted within 60 minutes. We do not read, index, or train on your documents.

No signup required

The free tier handles most day-to-day work. You only create an account if you want history, larger files, or batch automation.

FAQ

Questions people ask.

Can watermarks be removed later?

Not easily – once flattened, they're baked into the page rendering.

Any transparency limit?

Any opacity between 5% and 100% is supported.

Is PDF Books Lib really free?

Yes. The free tier covers everyday use – you can watermark several files per hour without an account. Pro unlocks larger uploads and batch jobs.

What happens to my files?

They live in an encrypted staging area for at most one hour, then they are permanently deleted. Nobody on our team can browse them.

Do I need to install anything?

No. Everything runs in your browser against our servers – Windows, macOS, Linux, iOS and Android are all supported.

Is Batch-friendly free to use?

Yes. Batch-friendly is free on the no-signup tier with no watermark added to your files. A paid plan only lifts batch and file-size limits for heavy users.

Do I need to install software or create an account for Batch-friendly?

No. Batch-friendly runs entirely in your browser - there is nothing to download and no account is required to get started.

Are my files private when I use Batch-friendly?

Yes. Uploads travel over an encrypted connection, are processed in an isolated pipeline, and are permanently deleted from our servers within 60 minutes. We never read, index or train on your documents.

What is the largest file Batch-friendly can handle?

On the free tier Batch-friendly accepts files up to 100 MB. Larger documents are supported on the paid plan, or you can split a big file first.

Does Batch-friendly work on mobile and every browser?

Yes - Batch-friendly is fully responsive and works in Chrome, Safari, Edge and Firefox across Windows, macOS, Linux, iOS and Android.

Will Batch-friendly change the rest of my document?

No. Batch-friendly only applies the change you make and leaves the rest of the pages, fonts and layout exactly as they were.
