A useful thing to know
Can I watermark only selected pages?
Yes. Leave Pages empty to watermark every page, or enter ranges such as 1-3, 5. Watermark text is rendered locally so multilingual text can be used.
How we handle your dataWatermark PDF guide
Add a visible label without hiding the document
A watermark can mark a document as draft, confidential, sample, copy or for a particular recipient. FileVoxa lets you choose text, position, opacity, font size and rotation so the label is noticeable without completely covering the underlying page.
Opacity matters. A very dark watermark can make forms and small text difficult to read, while an extremely faint watermark may disappear when printed or viewed on a low-quality display. Test a result and inspect both light and dark areas of the page.
A watermark is a visual notice, not a security control. It does not prevent copying, screenshots or editing by someone with suitable software. Share sensitive files only with intended recipients.
Practical checklist
Keep the page readable
- Use concise watermark text.
- Choose moderate opacity so underlying content stays legible.
- Check different page layouts before final use.
- Keep an unwatermarked original for future editing.
