What is PDF Compression?
PDF compression reduces document file size by optimizing internal resources such as embedded images, fonts, and metadata. The result is a smaller file that loads faster, uploads quicker, and is easier to share — while keeping document content readable and functional.

Compression Level Guide
Light compression reduces file size minimally while maintaining near-original quality. Medium compression balances size reduction against visual quality. Heavy compression produces the smallest files with more noticeable quality trade-offs — best for documents where text content is more important than image sharpness.
