Frequently Asked Questions
Which preset should I choose?
Use "Maximum compression" for sharing online where file size matters most, "Balanced" for everyday use, and "Minimal compression" when print quality matters most.
Will compression reduce image quality inside the PDF?
Yes, more aggressive presets downsample embedded images more heavily, which is where most of the size reduction comes from.
Why does this tool need a specific server tool installed?
True PDF compression (recompressing embedded images and streams) requires a real PDF-processing engine — Ghostscript is the standard open-source tool for this.
