We really care about keeping your information private.The thing that sets us apart is that we do everything to protect your privacy.Most online tools that add watermarks do things in a way that's not safe.You have to upload your document to their website and then they do something with it and after that you can download the document with a watermark.During this time you have no idea what is happening to your document.At OncePDF we do things differently.We do all of our work in your web browser so everything stays on your computer.This means that OncePDF is doing all the work with your document locally inside your web browser and that is a big deal for your privacy.OncePDF and your privacy are very important, to us and we want you to feel safe when you use OncePDF to add watermarks to your documents.

Protect and Share Safely
Once you’ve successfully watermarked your documents, you might want to optimize them before sending them out. A high-resolution logo can sometimes increase your file size, but you can easily use our PDF compression tool to shrink it down for a quick email attachment. Or, if you realize you only need to send a specific section of your newly branded document, you can quickly split your PDF pages to isolate exactly what you need.
Watermarking is a crucial step in professional filing and document sharing. It sets a clear boundary, establishes ownership, and deters unauthorized sharing. And if you’re dealing with incredibly sensitive information, pairing a solid watermark with a strong password using our PDF protection tool creates an unbeatable defense for your files. We believe that robust security and professional branding should be accessible to everyone, without sacrificing speed or privacy. So go ahead and stamp your mark on the world, knowing your files are completely safe with you.
