About this tool

Compression rebuilds each page as a compressed picture at the quality you select, which is what makes image-heavy and scanned PDFs dramatically smaller.

Because pages become images, text in the compressed file is no longer selectable or searchable. Keep the original if you need the text layer, and compare the size shown before and after.
