FAQ
Frequently asked questions
Can I use my own image as a watermark?
Currently text-only with full control over font, color, opacity and position. Image watermark is on the roadmap.
Does the watermark appear on every page?
Yes — applied uniformly across every page in the file.
Is Filigrane PDF really free?
Yes — every tool on PDFLabz is free with no daily limit, no account, and no watermark.
Are my files private?
100%. This tool runs entirely in your browser using JavaScript. Your files never reach our servers.
Is there a file size limit?
Up to 100 MB per file. Larger files just take longer because everything runs locally on your device.
Do I need to install anything?
No installation. Any modern browser (Chrome, Firefox, Safari, Edge) on any OS works.
