Frequently Asked Questions
Is the PDF watermark tool free?
Yes. The Aservus PDF Watermark Tool is completely free with no registration, no account, and no cost. There are no usage limits, no subscription tiers, and no Aservus watermarks added to your output file — only the watermark you create yourself.
Is it safe to use?
Yes. Your files are transmitted over an encrypted HTTPS connection and deleted from our server immediately after your watermarked PDF is ready for download. We do not store, read, or share your documents at any point.
Can I use my company logo as a watermark?
Yes. Switch to the Image tab in the settings panel and upload a PNG or JPG logo file. You can control the scale of the image and its position on the page using the 9-point placement grid. The logo is embedded into every page of the PDF automatically.
Does it watermark all pages of the PDF?
Yes. The tool automatically applies your watermark to every page of the PDF. You do not need to configure it page by page. Long documents such as contracts, reports, and e-books are fully covered in a single click.
Can I control the transparency of the watermark?
Yes. The Opacity slider lets you set the watermark from fully solid (100%) to nearly invisible. A typical setting for a confidentiality stamp is 30–50% opacity so the document content remains clearly readable beneath it.
Does this work on Mac, iPhone, and Android?
Yes. The Aservus PDF Watermark Tool is entirely browser-based and works on any operating system and device — Windows, Mac, Linux, iPhone, iPad, and Android — with no software to install and no plugins required.
