how to permanently redact a PDF on iPhone and verify the protected copy
Drawing a temporary annotation over a PDF is not enough; a reliable workflow must apply the chosen redactions to a new output and reopen that copy for verification.
簡短回答
Start by importing the PDF and reviewing every page. Mask My File can use OCR and exact-text search to surface matching content, but a missed or incorrect detection remains possible, so manual drawing, region adjustment and deletion stay available. Apply the selected solid masks or supported replacements to a new protected copy rather than changing the original. Reopen the resulting PDF, zoom in, move through every page and check that hidden text or regions are not exposed before the file is marked Private Ready. If a search finds no match, the source remains editable so the user can correct the query or add a manual region.
Try Mask My File on a real example first, and check the current App Store listing for exact features and pricing before you decide.
挑選前要注意什麼
- Review every PDF page instead of trusting OCR alone
- Add, resize or remove manual regions when detections are incomplete
- Search for exact repeated text and inspect every match
- Generate a new protected PDF while preserving the original
- Reopen, zoom and verify the output before it is marked ready
實用的決策步驟
- Import a sample PDF and navigate through all of its pages.
- Run OCR or exact-text search, then inspect every suggested match.
- Draw or adjust regions for anything the automated pass missed.
- Create the new protected copy without overwriting the original PDF.
- Reopen the output and inspect every page at readable zoom before sharing.

常見問題
Is drawing a black annotation over text permanent redaction?
Not necessarily. Use a workflow that applies the redaction to a new protected output, then reopen that output to confirm the underlying detail is not exposed.
What if OCR does not find the private text?
The file remains editable. Adjust the search, draw a manual region or correct the selected area, then generate and verify a new copy.
Does the app overwrite the original PDF?
No. It creates a new protected copy so the original can remain separate.
