Strict Target KB Limits (100KB, 200KB & 500KB)

Government job portals like SSC, UPSC, and state PSCs require uploaded PDF certificates to stay strictly below 100 KB or 200 KB. Our iterative compression engine calculates precise stream quantization so your PDF never exceeds the portal ceiling.

  • One-click presets for 100KB, 200KB, and 500KB limits
  • Output file size verified strictly under your chosen ceiling
  • Real-time before and after size calculation
White Paper Mode
Sharp Dark Text

Background Noise Flattening & High-Contrast Ink

Scanned certificates often waste 60% of file size storing dirty grey background texture and scanner noise. Our background flattener cleans scanner yellowing to crisp white, slashing byte weight while making printed letters stand out sharply.

  • Cleans scanner grain, shadows, and yellowed paper tint
  • High-contrast text clarity for automated OCR reading
  • Massive file size savings without blurring small fonts
Multi-Page Support
Smart Page Budget

Multi-Page Budgeting & Stream Optimization

Compressing multi-page marksheets or court affidavits evenly is difficult. SizeFix allocates byte budgets page by page so dense tabular data stays readable and lighter pages don't take up unnecessary space.

  • Compresses multi-page PDF documents seamlessly
  • Intelligent per-page stream budgeting preserves fine tables
  • Zero dropped pages, broken hyperlinks, or distorted graphics

Frequently Asked Questions (FAQ)
Why do traditional compressors make scanned PDF text blurry?
Standard compressors simply downscale image resolution into low-DPI mush. SizeFix flattens paper noise and background texture first, allowing high DPI (150-200 DPI) text to remain crisp at low KB.
Can I compress password-protected PDF files?
You must unlock the PDF first using our 'Unlock PDF' tool to remove the encryption password, then compress it here seamlessly.
Is my confidential bank statement or degree certificate secure?
100% secure. Processing executes entirely inside your browser using WebAssembly. No documents are transmitted across the internet.

100% Client-Side Confidential Security

Processed entirely in your device's web browser RAM. Your personal files and documents never leave your machine.
