Recommended, Maximum Compression, and High Quality
Recommended
A balanced setting for most PDFs. Embedded images are reduced while the pages should stay easy to read.
Maximum Compression
Uses stronger image reduction when a smaller file matters more than fine image detail.
High Quality
Uses lighter image compression so photos and scans stay clearer, with a smaller size change.
Why some PDFs cannot be compressed much further
Text and vector drawings are already compact. Recompressing them would not shrink the file without turning the pages into images. A PDF whose images are already compressed, or that has little image data, may stay about the same size. PixelTextAI only offers a download when the new file is actually smaller.
