Compress PDF: what to know

Reduce a PDF's size for an attachment or upload limit. Basic compression tidies the file while retaining selectable text. Strong compression renders pages into images, trading document features and detail for a potentially smaller result.

Already optimized files may shrink very little. Strong compression can change how text is searched, selected and read by assistive technology. Review small text and diagrams before replacing a higher-quality version.
