Compress a PDF to 100 KB
Many application portals cap document uploads at 100 KB. The target is already set: add your PDF and the tool steps through stronger settings until the file fits, then tells you the final size.

Frequently asked questions
What if it can’t reach 100 KB?
Very long documents may not fit. Remove pages you don’t need, or convert to grayscale first — both cut size dramatically.
Will the document still be readable?
The tool uses the highest quality that fits your limit, so text stays readable for normal one-to-five page documents.
