BleachBit

BleachBit is a free and open-source utility that frees disk space and helps protect privacy by cleaning unnecessary files from the system and applications. It runs on Windows, macOS, and Linux and offers both a graphical user interface and a command-line interface for automation.

The program provides cleaners for many applications and system components, enabling users to delete browser caches, cookies, history, logs, temporary files, and other junk. It includes a dry-run feature that shows what would be deleted before actually performing the cleanup, reducing the risk of accidental data loss.

For privacy and security, BleachBit provides options to securely delete files and to wipe free disk space to prevent recovery of deleted data. It supports batch cleaning and can be configured to run on a schedule or integrated into scripts.

BleachBit is released under the GNU General Public License version 3 (GPLv3) or later, and its source code is maintained publicly on its website and repositories, inviting community collaboration.

Users should review cleaners before running them to avoid removing needed data, especially in enterprise environments or with non-standard applications.
