How It Works

Sanitizr parses file types using known extensions and applies file-type-specific cleaning:

• Images: Clears EXIF tags using ExifInterface
• PDFs: Uses OpenPDF to remove PDF info
• Office Docs: Apache POI strips metadata
• Videos/Audio: Leverages FFmpegKit to drop metadata
• EPUBs: Parses and clears <metadata> from OPF
• Archives: Extract → sanitize → recompress using Commons Compress
