Open File Viewer

Open File Viewer is a versatile, framework-agnostic SDK designed for embedding file previews into modern web applications. It supports a wide range of file formats including PDFs, Office documents, images, audio/video, archives, emails, CAD, GIS, and 3D files, all within a stable, unified container. Compatible with native JavaScript, React, Vue, and Svelte, it allows developers to integrate a robust preview system effortlessly. The SDK offers two integration methods: a quick drop-in component with a built-in UI for immediate deployment, and a plugin-based core that enables custom rendering, WASM integration, or server-side conversions, suitable for advanced use cases. Its modular architecture includes pre-built plugins for common formats like PDF, Office, EPUB, images, and multimedia, with the flexibility to add custom plugins as needed. All previews are rendered within your DOM containers, supporting dynamic resizing, dark mode, download options, and error handling. Designed for real-world applications, it handles diverse document types—from business documents and engineering files to media assets and archives—making it ideal for web projects, backend systems, low-code platforms, or pages without a framework. The SDK’s API is minimal yet extensible, focusing on core functionalities such as container management, file handling, plugin integration, and event callbacks, enabling continuous evolution of file preview capabilities without rebuilding from scratch.
