Watermark, password-protect, and restrict your PDFs. No uploads — everything happens in your browser. 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. Encrypt (Pro) Lock your PDF with a user password (required to open) and an owner password (required to edit). Recipients without the password simply cannot access the file. Restrict permissions (Pro) Disable printing, copying, or modifying at the document level. Share a PDF that can be read but not duplicated. Wipe metadata (Pro) Remove the author name, creation tool, timestamps, and any other metadata embedded in the file before sending it out. HOW IT WORKS Click the PDF Armor icon and open the side panel. Drag and drop a PDF (or click to browse). Apply watermark, encryption, permissions, or metadata wipe. Hit Download — your protected PDF is ready. The entire process takes a few seconds. No account required for free features.

No file uploads, no cloud storage, no third-party access. The only network calls are for subscription verification and optional feedback — never your documents.
