- Upload your PDF files: Select or drop 2 or more PDF documents into the workspace.

Preserving Page Dimensions & Formatting
A common pitfall with generic PDF mergers is that they force all documents into a single rigid page size (such as forcing US Letter pages into A4 or landscape diagrams into portrait mode).
EcrioX preserves the unique coordinate systems, rotation flags (`/Rotate`), and bounding boxes (`/MediaBox`, `/CropBox`) of every single incoming page. Whether combining an A4 invoice, an architectural blueprint, and a US Letter report, each page retains its authentic dimensions.
Privacy & Security: 100% In-Browser Execution
Legal agreements, financial contracts, and personal records should never be uploaded to unknown third-party cloud servers. EcrioX merges documents locally inside your web browser. No document data is transmitted over the internet, and no copies are stored on external infrastructure.
