Frequently Asked Questions

PDF compression reduces file size by optimizing images, removing duplicate objects, compressing streams, and stripping unnecessary metadata — all while preserving readability and print quality.

The default compression settings balance size reduction with quality. Text and vector graphics remain unchanged. Images may be resampled, but the difference is typically not noticeable for screen viewing.

Compression results vary depending on the content. PDFs with large images typically see 40-70% size reduction. Text-heavy PDFs with few images see smaller reductions of around 10-20%.
