Preparing pages and checking signatures
Use custom formats, starting numbers, six positions, and page ranges while previewing any page.
Watermarks are visual marks, not irreversible DRM. Existing certificate signatures become invalid when the PDF changes.
Design additions that remain readable without obscuring the document
Watermarks, labels, logos, and page numbers should communicate status or ownership while preserving the original content. Use modest contrast, consistent placement, and explicit page ranges, then review difficult pages before export.
Step by step
- Define the message and scope
Decide whether the addition is a draft label, confidentiality notice, ownership mark, date, or page number, and identify exactly which pages need it.
- Choose placement and contrast
Keep additions away from signatures, form fields, diagrams, and essential text. Use opacity that remains visible without dominating the page.
- Preview varied pages
Inspect light, dark, portrait, landscape, sparse, and dense pages because one setting can behave differently across a mixed document.
- Export and compare
Download a new copy, compare representative pages with the original, and confirm that numbering, ranges, spelling, and image quality are correct.
Decision guide
- Text watermark
- Useful for DRAFT, CONFIDENTIAL, dates, departments, case references, and other short repeated status labels.
- Logo or image
- Useful for brand or ownership marks; transparent padding and a clean source image make placement easier.
- Page numbers
- Useful for review and print workflows; choose the starting number, format, position, and page range deliberately.
- Selected pages
- Use when covers, signature pages, exhibits, or existing numbered sections must remain untouched.
Important limits
- Adding a watermark or page number rewrites the PDF and can invalidate existing certificate-based digital signatures.
- A visible CONFIDENTIAL label does not encrypt the file, prevent copying, or enforce access control.
- Very low opacity may disappear in print, while very high opacity can reduce readability and accessibility.
- Interactive forms, annotations, layers, and unusual page boxes require inspection after export because their stacking order can differ.

Common questions
Can I number only part of a PDF?
Yes. Set a page range and starting number, then preview the transition into and out of the numbered section.
Does a watermark protect the PDF?
It communicates status or ownership but does not provide encryption, permissions, tracking, or copy prevention.
Will the original file be changed?
No. The browser exports a new copy; retain the original until the result has been checked.
Watermark and number PDF pages without uploading
Add a text watermark or logo as one positioned mark or a tiled pattern, then add independently formatted page numbers to all pages or selected ranges. Both features can be applied in one export.
The original PDF pages remain underneath the visual overlays, so selectable text, links, and form fields generally remain. Saving any change invalidates existing certificate-based digital signatures, and a visible watermark is not irreversible DRM.
