Frequently asked questions

How does safe mode differ from full?
Safe mode removes microtype, off-page text, and white text but leaves the invisible layer alone — that is usually a scan's OCR layer, without which the document stops being searchable. Full mode removes that too.
Will visible text disappear?
No. Only fragments classified as hidden are removed; the visible page content is untouched.
What happens to ActualText?
The /ActualText and /Alt keys themselves are stripped while the painted glyphs stay in place, so the document looks identical.
