About Compress PDF

With the PDF Compress tool, optimize the KB/MB sizes of your files that take up too much space and don't fit in emails. Our smart image compression algorithm radically reduces sizes while keeping resolution at an imperceptible level.

Step by Step: How to Use?

  • Upload Large PDF: Select the PDF file whose size you want to reduce.
  • Choose Level: Select the quality-compression setting that determines how much your file will be reduced.
  • Optimize & Download: Save your smaller file to your device as soon as the system optimizes it.

Frequently Asked Questions

Does compression blur text?

Text is generally unaffected since it's vector-based. Only images are optimized; readability is always preserved.

Which compression level should I choose?

We recommend the "Recommended Compression" level for the best balance. If the email limit is exceeded, try the "High Compression" level.
