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.
短い回答
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.
