ExifCleaner

ExifCleaner is an open-source desktop application used to remove metadata from images, videos, PDFs, and other file types. It serves as a graphical interface for those who need to strip sensitive information from media files before sharing them, providing a visual alternative to command-line metadata tools like ExifTool.

The software is available for Windows, macOS, and Linux. Users can process files by dragging and dropping individual items or entire folders into the application window. On Linux, it is distributed as an AppImage, .deb, or .rpm package, while macOS users can utilize a universal binary that supports both Intel and Apple Silicon. Windows users can choose between a standard installer or a portable version.

Key features

• Batch processing of over 90 image, video, and document formats
• Drag and drop support for files and folders
• Folder recursion to process all files within a directory
• Metadata inspection to view before and after differences
• Privacy options to preserve orientation and timestamps
• Ability to save cleaned files as copies
• Removal of macOS extended attributes
• Support for 25 languages with in-app switching
• Zero telemetry with no network traffic or automatic updates

Built with Electron and Node.js, the application relies on ExifTool's stay-open protocol to handle file processing efficiently. It is designed for users who prioritize privacy and security, featuring a hardened architecture that includes Content Security Policy (CSP), Electron Fuses, IPC validation, and permission gates. The interface includes a dark mode that follows the operating system preference and provides a clear diff view to verify exactly what data was removed from each file.

The tool supports a vast array of formats, including RAW files from Canon, Nikon, and Sony, as well as common formats like JPEG, PNG, HEIC, and MP4. Because it operates locally without any phone-home capabilities, it ensures that the files being processed never leave the local machine.

ExifCleaner is positioned as a privacy-focused utility for the permanent removal of embedded file metadata.
