The default setting significantly reduces size with virtually no visible quality loss. You can adjust the compression level.
Yes, most PDFs can be reduced to fit within email attachment limits, making it very effective.
Images account for most of a PDF's weight, so a document that is only text and tables is already small and has little left to squeeze. A text-only PDF exported straight from Word at around 500 KB will typically shed only tens of kilobytes. Scans and photo-heavy files, on the other hand, routinely drop to less than half their original size.
Yes — the text layer is left untouched and only the images are re-encoded, so search, copy and screen-reader access keep working. If the original is a pure scan, though, it never had a text layer to begin with, and it stays unsearchable whether you compress it or not. Such a document only becomes searchable after OCR adds a text layer.
