PDFscaler Master Guide

A comprehensive developer and user reference manual on client-side sandboxes, algorithms, and in-browser workflows.

Technical Design & Sandbox Execution

PDFscaler runs 100% locally using standard HTML5 sandboxing, RAM buffers, and WebAssembly execution. Since we avoid cloud uploads, your data has zero exposure risk and runs at full hardware speeds.

Core Modules

• PDF Editing Layer: Reads page dict tree catalogs, splits ranges, compresses DPI streams, or locks RC4/AES structures.
• Image Studio: Processes dimensions and canvas pixel arrays directly inside the browser context.
• Financial suites: Computes amortizations, systematic plans, and percentages with strict math transparency.
