Frequently Asked Questions

Can I customize the watermark appearance?

Yes. You can control the watermark text, font size (12-120pt), opacity (5-50%), rotation (horizontal, diagonal, vertical), color (gray, red, blue, black), and position (center, corners). Preview the result before downloading.

Is the watermark permanent?

The watermark is embedded directly in the PDF. It appears on every page and is visible when the document is viewed, printed, or shared. It cannot be easily removed by the recipient.

Can I add image watermarks?

Currently MiOffice supports text watermarks. Image watermark support (logos, signatures) is planned for a future update. Text watermarks cover most use cases including DRAFT, CONFIDENTIAL, and company names.

Does the watermark appear on all pages?

Yes, the watermark is applied to every page in the PDF. This ensures consistent branding or marking throughout the entire document.

Is my PDF uploaded to a server?

No. MiOffice processes everything 100% client-side in your browser. Your PDF never leaves your device. This makes it safe for confidential documents, contracts, and proprietary materials.
