Input and result

How we handle your files

Common questions

Good to know

Answers specific to this tool and its current capabilities.

How does PDF compression work here?+

Each page is rendered as an optimized JPEG at the selected quality and placed into a newly compressed PDF.

How can I make the PDF smaller?+

Move the image-quality control lower before processing. Lower values reduce detail but usually produce a smaller document.

Will PDF compression keep selectable text?+

No. Genuine image-based compression rasterizes each page, so the output favors smaller files over selectable text and vector content.
