## What Is Compresser PDF à 100Ko on PDFnology & How Client-Side Processing Works
Compresser PDF à 100Ko (https://pdf.dealnology.com/compress-pdf-to-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
### Will my PDF definitely be under 100 KB?
Yes! For 1-to-3 page certificates and ID documents, our 100KB target algorithm adjusts page scale and quality iteratively until the output is strictly under 100 KB.

### Will the text on my marksheet or Aadhaar still be readable at 100 KB?
Yes. Instead of over-compressing blindly to 15 KB, our smart calibration targets ~85–98 KB so you retain maximum possible text sharpness within the 100 KB limit.
