PDF Merge

Visual Order Control and High-Fidelity PDF Merging

Integrates an intuitive drag-and-drop reordering UI powered by UIkit Sortable with robust server-side PDF structure analysis and fast merging execution. Consolidates multiple PDF files into a single, high-quality document without compromising document layouts, vector layers, or embedded fonts.

Architectural Pipeline

Uploads multiple selected PDF files asynchronously via the Fetch API, provisioning unique structural references (serverName) for backend tracking.
Serializes the visual compilation order adjusted via the UIkit Sortable component into a deterministic JSON array sequence.
The server-side PDF engine parses the sorted sequence array and seamlessly stitches the underlying binary file streams without losing original fidelity.
Following asynchronous API validation for the 2-point requirement, unlocks an isolated, session-secured file stream to safely download the unified document.
