Clean temporary files, review storage and check PC health without ads, bundled software or fix-everything promises. For Windows 10 and 11, 64-bit. Portable download, review before cleanup.
Download Rain Cleaner Free with the buttons at the bottom of this page or at raincleaner.eu. Windows 10 and 11, 64-bit. There is an installer and a portable version. No ads, no bundled software. Want more? Pro has a free 14-day trial, no card required.
Rain Cleaner is built around inspection before deletion. You see what was found and why it may be removable, then you choose what happens next. There is no fake counter of thousands of problems.
The Free version is a complete tool for manual cleanup and checks:
Pro is for the things you would otherwise repeat by hand. Monthly 5.99 euro, yearly 34.99 euro or 74.99 euro once, with a free 14-day trial and no card.
No ads. No bundled software. Current Windows builds are unsigned while our company code-signing verification is being completed, so Windows may show a warning; SHA-256 hashes are published on the Trust page so you can verify the file.
You can use Settings → System → Storage, Storage Sense and Disk Cleanup without Rain Cleaner. Rain Cleaner is for people who want those checks organised in one interface with review before action. See our guides on freeing disk space safely and on the Windows 11 PC health check.
