Standard
Editable vector output. Text stays selectable and sharp. Note: removed content is covered, not destroyed — it can still be extracted from the file.
Flattened (true removal)
Each page is re-rendered as an image. Removed or covered content is permanently gone — use this for redactions. Larger file, text no longer selectable.
