Technical Architecture & In-Browser Processing

A 10MB ceiling gives creative studios and design agencies generous headroom for multi-page brand books, graphic design portfolios, and client pitch presentations. FitSize executes deep stream deduplication and lossless Flate packing, shrinking 100MB print-ready exports to 10MB without introducing banding across subtle gradient fills or crushing delicate typographic kerning.

At 10MB, our compression algorithm processes extensive legal discovery archives, architectural schematics, and medical case histories. The engine applies advanced CCITT Group 4 and Flate encoding to scanned records while isolating vector annotation layers, delivering high-speed zooming and smooth page navigation on low-powered tablets.
