PDF Tools
Compress PDF
Make a PDF smaller. Choose a light structural pass, or a stronger pass that re-renders each page as an image at the resolution and quality you pick.

Load a PDF and pick a mode to see the result here.
Already-optimised PDFs sometimes grow slightly in light mode. If that happens,
keep the original — the tool will tell you which is smaller.
Good to know
- The strong mode rasterises pages, which flattens text into pixels — the result is smaller but no longer selectable or searchable.
- Use the light mode first: it rewrites the file structure without touching page content, and is lossless.
