PDF compression works by removing redundant data, downsampling embedded images, and applying lossless or lossy compression algorithms to reduce the overall file size. Docuvory offers three quality tiers so you can balance file size against visual fidelity. The Compact mode applies aggressive image downsampling, ideal for archiving or messaging apps. Balanced mode is a middle ground for everyday document sharing. High Quality mode minimises compression but still removes unnecessary metadata, resulting in a slightly smaller file that is indistinguishable from the original at normal reading distances.
