Private file preparation for Windows
Make files ready to share—without uploading them.
Review, mask and export images, PDFs, pasted text, DOCX and XLSX files on your own device.
Windows x64 · v1.4.1 · English / 简体中文 interface · paid licences are one-time purchases
Real product proof
Three visible steps. One file stays on your device.
The screenshots below are from the real v1.4.1 Windows app. Detection assists review; it does not replace your final check.
Select a supported file from the Windows device.
Inspect suggestions and add or adjust masks manually.
Check the result before it leaves your device.
Five workflows
Use the file path that matches the material.
Each path has its own review and export behaviour. Unsupported or hard-to-read content must be handled manually.
Images
Draw masks, review local OCR suggestions and export PNG or JPG.
Review supported PDFs page by page and export a prepared copy.
Text
Paste text, inspect pattern suggestions and copy the masked result.
Word
Review readable content and document metadata before export.
Excel
Review readable cells and workbook metadata before export.
Processing boundary
Built to work on the device in front of you.
No cloud account, remote font or AI API is required for the app’s file-processing workflows.
Files are selected from the device. Originals are not modified; the app creates a new file only when you export.

Know before installing
Clear boundaries build safer habits.
This tool assists preparation. It does not guarantee complete anonymisation or replace your organisation’s review policy.
Review is required
OCR and pattern detection can miss content. Inspect every page, mask and exported file before sharing.
Originals stay put
The app creates a new copy only when you export. Keep your original and confirm the new result.
Publisher warning
The current installer may appear unsigned or from an unknown publisher. Verify the official download path and follow your security policy.
Which languages are built into the app?
The current v1.4.1 interface and local OCR support English and Simplified Chinese.
Does it modify the original file?
No. A new file is created only when you export.
Does the app guarantee anonymisation?
No. Detection can miss content. Human inspection of the final export is required.
