AxCrypt Free is a popular open-source file encryption software that enables you to protect confidential files on your Windows computer securely. Designed for simplicity and security, it helps you lock personal data, financial records, business documents, and any sensitive file with strong AES-128 encryption. Whether you’re a home user or a small business, AxCrypt Free makes file encryption effortless without requiring any technical expertise.
What is AxCrypt Free?
AxCrypt Free is part of the AxCrypt 2.1 open-source suite licensed under the GNU General Public License (GPL) v3. It’s completely free for Windows users and comes with all the basic features required to encrypt, decrypt, and manage confidential files. The free edition supports AES-128 encryption, which is considered highly secure for everyday use.
Unlike traditional archiving or password-protecting methods, AxCrypt integrates directly into the Windows Explorer right-click menu, making it easy to encrypt or decrypt files with a single click. This straightforward integration is perfect for beginners who want to keep their data private without going through complicated settings.

How Does AxCrypt Work?
Once installed, AxCrypt automatically integrates into your File Explorer. Right-click on any file and choose the “AxCrypt” option to encrypt it using your chosen password. The file extension changes to “.axx,” indicating that it’s encrypted and unreadable to anyone without your password.
When you or another AxCrypt user opens the encrypted file, AxCrypt decrypts it on the fly after verifying your credentials. This makes the process seamless, allowing you to view or modify files securely and re-encrypt them when done.
It’s a lightweight utility that runs quietly in the background without affecting system speed. If you’re worried about high CPU load, you can also use Process Lasso Free to control AxCrypt’s background performance efficiently.
AxCrypt Viewer for macOS and Mobile
AxCrypt also offers a free Viewer Plan for macOS, iOS, and Android users. This plan allows you to view and decrypt encrypted files and access your password manager securely. However, note that editing or re-encrypting files is reserved for premium users. The viewer is ideal for people who receive encrypted files and only need read-only access on non-Windows devices.
This cross-platform accessibility makes AxCrypt especially convenient for professionals who share encrypted files with clients or colleagues on different operating systems.

AxCrypt Free vs AxCrypt Premium
It’s important to understand that the current AxCrypt installer automatically starts with a 30-day Premium trial. After the trial ends, the app turns into a limited free version that can only decrypt existing files, not encrypt new ones. To continue encrypting files without restrictions, you must install the AxCrypt 2.1 GPL open-source version, which is the true “AxCrypt Free.”
The Premium version adds AES-256 encryption, secure file shredding, password manager editing, key sharing, and offline file encryption. However, for most personal or small office needs, the 2.1 open-source version remains completely sufficient and truly free.
For additional protection, you can also try Easy File Locker or My Lockbox, both of which work offline and add folder-level security.
Why Choose AxCrypt Free?
- Beginner-friendly design: Encrypt and decrypt files in seconds using simple right-click options.
- Open-source transparency: The 2.1 GPL edition is community-audited and privacy-respecting.
- Offline and cloud support: Works without a cloud account, but integrates with major storage services.
- Lightweight performance: Runs smoothly without draining CPU or memory.
- Cross-device access: View your encrypted data on mobile using AxCrypt Viewer.

Security and Privacy
AxCrypt uses a proven AES-128 encryption algorithm to protect your files from unauthorized access. Your password never leaves your device, and the encryption process happens locally. Even if someone steals your cloud backups, your encrypted files remain unreadable.
For additional protection, you can combine AxCrypt with folder-hiding utilities like Lock a Folder to add another privacy layer to sensitive directories.

Download AxCrypt Free
Although the AxCrypt website still references version 2.1 as open-source under GPL v3, the publicly distributed Windows installer (including version 2.1.1693.0) launches a 30-day Premium trial and disables encryption afterward. The genuine GPL-licensed code exists only as source on AxCrypt’s GitHub, not as a ready-to-use build.
Conclusion
AxCrypt Free remains one of the most respected open-source encryption tools for Windows. While the newer versions limit encryption after the trial, the original AxCrypt 2.1 GPL edition continues to offer full AES-128 file encryption at no cost. It’s simple, effective, and trustworthy for protecting private or professional documents.
For users who value privacy, transparency, and offline control, AxCrypt Free (GPL) stands out as a dependable choice. And if you ever need additional power features like AES-256 or file shredding, upgrading to Premium or exploring tools like VeraCrypt can extend your data security even further.
