## What Is ضغط ملف PDF on PDFnology & How Client-Side Processing Works
ضغط ملف PDF (https://pdf.dealnology.com/compress-pdf) 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
### How can I compress PDF to 200KB online for free without losing quality?
Upload your PDF file above, click the "Under 200 KB" quick target button in the compression panel, and click "Compress PDF Under 200 KB". Our smart calibration engine keeps text and stamps razor-sharp while guaranteeing the output file is strictly below 200 KB.

### Can I resize a PDF file to 100KB, 150KB, 300KB, or 500KB?
Yes! You can click any preset button (50 KB, 100 KB, 150 KB, 200 KB, 300 KB, 500 KB, 1 MB) or type any custom number into the "Custom KB" box to resize your PDF to the exact size required by your portal.

### How is PDFnology better than iLovePDF or 11zon for compressing PDFs to 200KB?
iLovePDF only offers Extreme, Recommended, and Less compression without letting you set a 200KB limit, while cloud tools upload your personal IDs and certificates to remote servers. PDFnology gives you exact 100KB/150KB/200KB targeting 100% locally inside your browser.

### What if I have a JPG image that I need to convert to a compressed PDF?
Use our JPG to PDF Converter (/jpg-to-pdf) or Scan to PDF tool (/scan-to-pdf)—both tools let you combine multiple JPG/PNG images into a PDF and set a 100KB, 200KB, or 400KB size cap in a single step.

### Is it safe to compress confidential PDFs like Aadhaar, PAN, or bank statements here?
Yes, it is 100% safe. PDF.dealnology.com processes your PDF directly inside your web browser memory. Your files are never uploaded to any external server.

### Why did my text-only PDF file size not decrease by 80%?
Pure vector text PDFs are already very small. If you need to shrink a scanned or image-heavy PDF dramatically, select Extreme Compression or pick an exact Target KB limit.
