Frequently Asked Questions

Frequently Asked Questions

Learn more about how TyagiHub's private client-side watermark offline engine works.

Does applying a watermark reduce the quality of my PDF files?
No, not at all! TyagiHub uses a native vector-based overlay system that appends watermark paths directly onto the original PDF canvas coordinates. Text is rendered as high-fidelity vector outlines to ensure zero quality degradation.
Can I apply watermarks to password-protected documents?
Yes, you can. When a secure or password-encrypted file is dropped into our workspace, our local decrypt utility prompts you for credentials prior to starting the layout rendering stream.
What is the difference between Overlay and Underlay options?
Overlay: The watermark text or image is stamped directly on top of the pages, covering the document lines completely. This provides excellent security safeguards.
Underlay: The watermark is positioned strictly behind existing written elements, which renders it elegantly as a subtle background pattern without sacrificing document legibility.
Are my uploaded files safe? How are they stored?
Your files are 100% safe. TyagiHub processes files strictly in-memory using client-side WebAssembly wrappers right inside your browser sandbox. None of your bank reports, identifiers, or drafts are transmitted over the network to remote clouds.
