Key Features

Instant PDF Rendering

Transform raw Base64 strings into fully readable PDF documents instantly. Our engine handles multi-page documents, embedded fonts, and vector graphics with zero delay.

Smart Header Parsing

Automatically detects PDF magic numbers (JVBERi0) and MIME types. Our parser intelligently cleans and prepares your data stream for strict Adobe-compliant rendering.

Secure Document Export

Save your decoded documents locally with a single click. We generate optimized binary blobs to ensure your downloaded files remain compatible with all professional PDF readers.

Interactive Inspector

Leverage native browser tools to search text, rotate pages, and zoom. Inspect the layout and content of your encoded documents exactly as they would appear in a desktop viewer.

High-Volume Processing

Optimized for enterprise-scale reports and complex documentation. Our memory-safe architecture handles massive Base64 payloads without freezing your browser interface.

100% Client-Side Privacy

PDFs often contain sensitive info. Your data never leaves your machine; all decoding occurs locally in your browser. No files are ever uploaded or stored on our servers.

100% Client-Side Processing

Privacy is a feature. Your JSON data is processed entirely in your browser using JavaScript. We never upload, store, or see your data. It stays exactly where it belongs: with you.
