Mask My File

Spot private details, decide exactly what to black out, and share a verified copy while the context people need stays intact.

Mask My File · App Store

A single private workflow for every file

Preview images and PDFs at full width, zoom up to 5× and draw exact areas by hand. Search every match across Text, JSON, XML, HTML, CSV, TSV and RTF, then choose stars, partial masks, placeholders, pseudonyms or removal. Metadata is stripped wherever the format allows.

Private Ready means re-checked

Mask My File writes a fresh copy, reopens it and confirms the protected file is still valid before it shows Private Ready. Your original stays exactly as it was.

Review up to 100 files together

Give each file its own preview and manual selections, search the same private text right across the set, then export every verified copy in one go.
