Overview

Product summary

Review the store description, core capabilities, and common use cases.

Protect your PDFs before you share them. Add watermarks, set passwords, restrict printing and copying, and strip hidden metadata — all without uploading a single file.

PDF Armor runs entirely inside your browser. Your documents are never sent to a server, never stored in the cloud, and never seen by anyone but you.

WHAT YOU CAN DO

Watermark

Drop a PDF into the side panel and add text watermarks in seconds. Control the text, font size, colour, opacity, rotation, and position. Drag and resize the watermark directly on the preview. Choose from presets — diagonal, centre, corners, or tiled — or place it exactly where you want.
