Frequently asked questions

How do I compress a PDF to under 300KB?

Upload your file above, keep "Compress to a target size" checked, set 300 in the KB field, and run it.

Will the PDF still look good at 300KB?

Text documents usually hold up well; photo-heavy pages show more visible quality loss at this size.

Is my file uploaded to hit 300KB?

No, the whole thing runs in your browser.
