The Real Problem

You combine multiple scanned images into one PDF, but the file jumps to 3MB+. The upload limit is 1MB. Now you’re stuck retrying uploads.

Why JPG to PDF Files Become Too Large

Why Reducing DPI Matters

300 DPI is for printing. Upload portals only need 100–150 DPI. Lowering DPI reduces pixel data, cutting file size without hurting readability.

Color vs Grayscale Impact

Color images store more data layers. Converting to grayscale removes extra color information, shrinking file size while keeping text sharp.

Generic Tools vs Smart Compression

Generic Tools
  • Only merge images
  • No size optimization
  • Result: oversized PDF
This Tool
  • Compression + conversion
  • DPI + grayscale optimization
  • Result: PDF under 1MB

How Compression Actually Works

The system reduces pixel density, removes redundant color data, and applies efficient encoding. This minimizes file size while preserving visible text clarity.

Why This Method Works

Instead of blindly shrinking files, the tool optimizes image structure. It keeps edges sharp and removes unnecessary data so the PDF meets strict limits without quality loss.
