## What Is JPG to PDF Under 100KB on PDFnology & How Client-Side Processing Works
JPG to PDF Under 100KB (https://pdf.dealnology.com/jpg-to-pdf-under-100kb) is a free, zero-upload browser utility engineered by Dealnology that executes document manipulation 100% locally inside the user's device memory using WebAssembly, pdf-lib v1.17.1, Mozilla PDF.js v3.11.174, and HTML5 Canvas APIs. Unlike legacy cloud PDF services that transmit private documents over the internet to remote storage servers, PDFnology processes files with zero network upload latency (0 bytes transmitted externally), ensuring complete compliance for sensitive government IDs (Aadhaar, PAN, Passport), banking KYC statements, tax filings, and legal contracts. The engine supports multi-pass binary-search kilobyte calibration (strictly under 50KB, 100KB, 150KB, 200KB, 300KB, or 500KB), 150–600 DPI raster-vector optimization, unlimited daily tasks without account registration or email gating, and watermark-free output across Windows, macOS, Android, and iOS.

## Frequently Asked Questions
### Why does a normal JPG-to-PDF converter create a 3 MB PDF from my phone photo?
Smartphone cameras shoot 12MP–50MP photos that weigh 3–6 MB each. Our specialized tool downscales and optimizes the image stream while building the PDF so the final file lands under 100 KB.
