關於此工具
選取範圍或文字符合項目。本機引擎會永久移除所選文字、重疊的影像像素及相交的圖形，再填入純色。除非將所有頁面點陣化，其他文字仍可選取。模糊和馬賽克不適用於永久遮蔽。
新檔案會清除舊版本、未使用物件、中繼資料、附件、書籤、註解、連結和表單，並使數位簽章失效。畫筆可能移除附近內容。搜尋僅尋找可擷取的文字，不執行 OCR，也不跨行比對；掃描文件應手動選取範圍。未選取的副本可能保留。分享前請檢查下載檔案的每一頁。

常見問題
Yes. Export applies content removal and writes a new PDF with old revisions and unused objects discarded. Other unselected occurrences can remain, so review every page.
No. These effects retain visual information. Permanent redaction uses a solid fill after removing content.
Metadata, attachments, bookmarks, annotations, links and forms are removed. Touched vector objects may disappear beyond the selection boundary. Digital signatures are invalidated.
Use manual rectangles for scans. Text search and automatic patterns only find extractable text and do not run OCR.
