Why use this tool

Common problems

The PDF barely gets smaller
Text-heavy or previously optimized PDFs contain little removable data. Strong compression works best on image-heavy files.
The target size is not reached
Target size is best effort because readable quality and PDF structure impose a lower limit. Try Strong compression.

Frequently asked questions

Which compression level should I use?
Balanced is recommended for most files. Light retains more image detail, while Strong prioritizes a smaller download.
Will compression change the page order?
No. Pages remain in their original order and dimensions.
Are compressed PDFs retained?
