Hitting the Strict 50KB PDF Limit
A 50KB cap is one of the toughest PDF size restrictions imposed by legacy exam portals. To reach 50KB without sacrificing legibility, scan your single-page document in grayscale mode at 150–200 DPI before running it through Compressify's Strong preset.
Pro-Tips for 50KB PDFs
- Scan in Monochrome or Grayscale (removes color layer overhead).
- Trim wide white margins from the page edges.
- Select the Strong preset in the Compressify PDF tool.
