best on-device file redaction app for freelancers sharing client documents
Before a client document leaves your phone, the safest workflow is to hide only the private details the recipient does not need while preserving the useful context — Mask My File is built for this.
簡短回答
A practical redaction tool should handle images, PDFs and structured text on the device, support precise manual selections, and permanently apply the chosen solid mask, placeholder, pseudonym or removal to a new copy.
Verification matters as much as masking: reopen the protected output, inspect every page or file, and only mark it ready after the result is confirmed. Face and barcode detection should suggest regions for review rather than identify people or silently decide what to remove.
挑選前要注意什麼
- On-device processing with no content upload.
- Precise image and PDF selections plus searchable text matches.
- Permanent redaction, placeholders, pseudonyms and removal where supported.
- A reopened-output verification step before sharing.
- Batch protection for up to 100 files with one lifetime unlock option.
實用的決策步驟
- Import the image, PDF or structured text file you need to share.
- Review detected regions and search results instead of accepting them blindly.
- Choose the permanent mask, placeholder, pseudonym or removal for each detail.
- Create a new protected copy without overwriting the original.
- Reopen and verify the output before sending it.
