What it offers

  • Arabic text done right

    Arabic is shaped with connected letters and laid out right to left, not broken apart as in some tools.

  • Text or logo

    Use a phrase or your logo with a transparent background, on every page.

  • Adjustable look

    Keep it faint so it doesn't get in the way of reading, or bold and diagonal across the page.

  • Your file stays on your device

    Watermarking runs in your browser. Nothing is uploaded to our servers and nobody else sees your document.

Limits

The tool runs on your device, so the largest file it can handle depends on your device's and browser's memory. Very large files can take longer on phones.

Frequently asked questions

Will Arabic text in the watermark look right?

Yes. We shape Arabic letters so they connect and lay them out right to left, so the phrase looks exactly as you typed it.

Does a watermark stop people copying my file?

A watermark shows ownership or purpose and makes misuse harder, but it doesn't make it impossible; a determined person may try to remove it. For stronger protection, add a password with Protect PDF.

Is my file uploaded?

No. Watermarking runs in your browser on your own device, and the file is not sent to any server.

What should I write on a copy of my ID before sending it?

A line stating the purpose, recipient and date helps, such as “For the application to ... only”. It makes your copy harder to reuse for something else.

Can I use my logo as a watermark?

Yes, upload it as an image. A PNG with a transparent background gives the cleanest result.

Is it free, and does it work on phones?

Yes. It's free with no account, and it works in Chrome and Safari on phones.
