Frequently asked questions

How much smaller will it get?

It depends on the file — PDFs with redundant or uncompressed data shrink most. Already-optimised PDFs change little.

Is the PDF still editable and selectable?

Yes — this keeps the document structure and text intact; it only optimises how it's stored.
