BleachBit 4

BleachBit

BleachBit is a free, open-source disk cleaner and privacy manager for Windows and Linux. It frees up disk space, protects your privacy, and keeps your system clutter-free.

Key Features

• Cache & Junk Cleaning: Clears cache, cookies, temporary files, and logs from thousands of applications including Firefox, Google Chrome, Opera, and more.
• Secure File Shredding: Permanently shreds sensitive files so their contents can never be recovered.
• Free Space Overwriting: Hides traces of previously deleted files by overwriting free disk space.
• Database Vacuuming: Shrinks Firefox and Chrome databases without removing data.
• Windows Registry Cleaning: Removes MRU (most-recently-used) lists and other registry clutter.
• Cookie Manager: keep certain cookies (available since version 5.1.0)
• CLI & Scripting Support — Command-line interface for automation and power users.
• Extensible Cleaners: Write custom cleaners with CleanerML, or import winapp2.ini for thousands of additional Windows cleaners.

Why BleachBit?

Completely free with no adware, spyware, telemetry, or bloatware. Includes a preview mode so you can see exactly what will be deleted before committing. Runs portably from a USB drive on Windows.

BleachBit outperforms CCleaner 7 by avoiding its notorious issues like a confusing redesigned UI, aggressive cleaning that breaks browser settings and programs, and forced telemetry with bloatware background processes. Instead, BleachBit delivers open-source transparency, precise granular controls, including winapp2.ini support, and lightning-fast cleaning without hidden data collection or upsell nagging. Power users love its reliability over CCleaner 7's crashes and restricted features.
