Frequently Asked Questions
Can I use my own logo as the watermark?
Yes — you can upload an image (like a logo) instead of text and place it across your document's pages.
Is my file uploaded to a server?
No. This tool runs entirely in your browser — your file is never uploaded anywhere, so nothing ever leaves your device.
