Tmibao - File Redaction

Tmibao is a privacy protection tool that completes file, photo, and face information redaction locally on your device.

Text information in files is sensitive, and faces in photos may also reveal personal identity. Tmibao supports both document text redaction and photo face redaction, helping reduce the risk of sensitive information exposure before sharing files, publishing photos, or submitting documents.

Key Features:

• Supports common file and image formats including TXT, DOCX, PDF, JPG, PNG, and HEIC
• Detects sensitive text such as phone numbers, ID numbers, names, bank card numbers, emails, addresses, amounts, and case numbers
• Automatically detects and redacts faces in photos and images
• Offers five face cover styles: smiley, cat, dog, black silhouette, and solid black square
• Covers facial areas, head regions, and hairstyles to reduce facial feature exposure risks
• Supports manual review with individual choices to redact or keep each item
• Allows manual selection of text or face areas
• Creates new redacted copies without overwriting original files or photos
• Removes EXIF, GPS, and device information when exporting photos
• All recognition and redaction processes are completed locally without uploading user files or photos

Automatic detection may be affected by image quality, lighting, occlusion, angles, and handwritten content. Always review the redaction results before sharing, publishing, or submitting files.
