One PDF only. This browser-only version supports files up to 40MB and up to 120 pages.
The source file and output are processed in the current browser and are not uploaded to LittleOne Tools servers.
Current Scope
This version is limited to visible text watermark overlays for one PDF: add one watermark label across a continuous page range and export one new PDF.
It is not a full PDF editor and does not support image watermarks, live preview, free-form page range expressions, automatic collision avoidance, watermark removal, or existing-watermark detection/replacement. Dense page content may still be covered.
The watermark is only a visible overlay. It is not permission control, encryption, a digital signature, tamper protection, or an unremovable lock. This version works best with basic ASCII / Latin text.
Waiting for PDF
Upload a regular, unencrypted PDF to start configuring the watermark text, page range, position, angle, and opacity.

Single-line text. Keep it within 80 characters. This version works best with basic ASCII / Latin text.
Angle Preset
Angle semantics follow the visible page in the PDF reader. Rotated pages are remapped in that visual direction.
Start applying the watermark from physical page N.
Leave blank to continue through the document end.
Position Preset
Position semantics follow the visible page edges seen in the PDF reader. When centered, the edge gap does not affect placement.
This version uses a neutral gray text color and a standard font. Custom fonts, color picking, image watermarks, and automatic collision avoidance are not included.
Changing the filename affects only the download name. It does not mark the tool as dirty or change the current watermark settings.
New PDF Ready
Download immediately, or rename the file before downloading. Any result-affecting setting change invalidates the previous result immediately.
