Choose between text-preserving optimization and smaller scanned pages. Compare file sizes before keeping it.
Try the text-preserving method first. It can reduce overhead while keeping selectable text, but some documents will not get smaller. The scanned-copy method renders pages as images and can make some PDFs smaller at the cost of selectable text and possibly visual detail.
Best when you need search, copy-and-paste, or accessibility. Compare output size because a PDF that is already optimized may barely change.
Choose image quality and resolution to trade detail for size. This method rasterizes pages, so the output is not a good substitute for an editable document.
Open the new PDF and inspect small text, charts, and signatures before sending it. Keep the original until the result meets your needs.

It depends entirely on what the document contains. Scanned pages and photo-heavy files usually shrink a lot, while a text-only document may already be close to its smallest useful size.
The text-preserving pass keeps text selectable and searchable. The image-based copy rasterises pages, which often compresses much further but turns the text into pictures.
Yes. The tool reports the resulting size so you can see the saving and decide whether the trade-off is worth it.
