BleachBit
An open-source cleaner for removing junk and wiping sensitive traces.
BleachBit is a free desktop utility for Windows and Linux that removes temporary files, browser leftovers, logs, and other accumulated system clutter. It also includes privacy-focused deletion tools such as file shredding, free-space wiping, preview-before-cleaning, command-line automation, and custom cleaner rules.
Why it stands out
- Fully open source under GPLv3, with no ads, subscriptions, or bundled upsells described.
- Covers both cleanup and privacy deletion rather than only freeing disk space.
- Shows files before deletion, giving users more control than one-click optimizer tools.
- Includes CLI and scripting support for administrators managing multiple systems.
- Supports custom CleanerML definitions for advanced users who need app-specific cleanup rules.
Good to know
- Available for Windows and Linux; the page does not list macOS, mobile, or browser-extension versions.
- Secure deletion and free-space wiping are destructive actions, so users should review previews carefully before cleaning.
- Fleet automation and custom CleanerML cleanup require comfort with command-line use or rule writing.
- The tool emphasizes manual control rather than automatic background optimization.
