About Image to PDF & High-Fidelity PDF Assembly
FileLab Image to PDF is a tactile executive-grade staging desk for converting receipts, contract scans, presentation slides, and identification photos into unified, print-ready PDF files. Built on top of WebAssembly and the HTML5 Canvas 2D engine, every image is scaled, oriented, and compressed directly inside your browser's memory sandbox with zero network uploads.
Images are transformed into vector PDF streams entirely client-side using pdf-lib. No external API calls.
Customize page format (A4, US Letter, Fit), page orientation (Auto, Portrait, Landscape), and margin spacing.
Tune DPI quality balance from 40% to 100% with real-time output size estimation before compiling.
