1) Start With Medium Compression
Medium mode usually gives the best trade-off between smaller size and readability.
Compress PDF Without Losing Quality
If your file becomes blurry after compression, your settings are too aggressive. Use a balanced strategy instead.
2) Keep Text Vector-Clean
Avoid flattening text into low-resolution images. Text should remain crisp and selectable.
3) Optimize Images Smartly
- Use JPEG for photos and scanned pages.
- Use PNG for charts, logos, and line art.
- Downscale only beyond required print/screen size.
Final Tip
Always compare original and compressed output page by page before sharing externally.
