How to compress a PDF without losing quality
Simple methods to reduce PDF size while keeping good readability (images, DPI, practical tips).
Compressing a PDF is mainly about balancing file size and image quality.
1) Reduce image resolution (DPI) for web usage.
2) Lower JPEG quality for embedded images if they are too heavy.
3) Remove unnecessary objects (metadata, hidden content) when possible.
Tip: try multiple compression levels and compare the result at 100% zoom.
