遮蓋敏感資料
永久遮蓋身份證、護照、銀行戶口、信用卡和稅號、電話、電郵、出生日期，或你標記的任何位置。
使用方法
- 拖放 PDF。程式會自動找出身份證和護照號碼、銀行戶口、信用卡和稅號、電話、電郵和出生日期，並加上方塊。
- 逐頁核對：拖動方塊可移動，拖角落可調整大小，按 × 刪除，在頁面空白處拖曳可畫新方塊。
- 確認最後一頁後下載。黑色方塊下的內容會從檔案中刪除，不只是遮住。
疑難排解
掃描版的頁面找不到任何資料。
掃描版沒有文字可以搜尋。請手動畫方塊，或先用文字辨識（OCR）工具處理。
其中一頁變成了圖片。
如果某頁有無法直接修改的內容（例如特殊字型，或方塊下有非 JPEG 圖片），只有那一頁會轉成圖片再塗黑，確保不會洩漏。其他頁面保留原本的文字、清晰度和大小。
常見問題
Is the text really gone, or just hidden?
Gone. The text under each box is taken out of the page itself, image pixels under it are blackened, notes and links under it are dropped, and a black box is drawn on top — nothing replaced is kept anywhere in the file. The rest of the page stays as it was. If a page holds something that can't be edited in place, that page alone is rebuilt as a picture with the boxes painted in.
Does it find the personal data for me?
It proposes boxes over ID numbers (Hong Kong, Macau, Taiwan, mainland, Singapore, Malaysia, US, UK), passport numbers, bank accounts, IBAN, SWIFT and card numbers, tax and company numbers, phone numbers, emails and dates of birth. You check every page and can move, add or remove boxes before anything is removed.
Is my file uploaded?
No. Finding and removing both run on your device.
