Frequently Asked Questions
What does watermarking a PDF do?
Watermarking adds a semi-transparent text overlay to every page of your PDF. It is commonly used to mark documents as "Confidential", "Draft", or to add branding.
Can I customize the watermark text?
Yes. You can type any text you want in the input field before adding the watermark. Common choices include "CONFIDENTIAL", "DRAFT", "DO NOT COPY", or your company name.
Will the watermark affect the readability of my PDF?
The watermark is applied with low opacity (15%) so it remains visible but does not obscure the underlying content of your document.
Is my PDF uploaded to a server?
No. All processing happens entirely in your browser. Your file never leaves your device, ensuring complete privacy.
