9 best free encryption software I recommend 

The global demand for encryption solutions continues to surge as organizations and individuals alike prioritize data protection. In fact, in 2025, the encryption software market is projected to be worth about $17.06 billion, reflecting how critical data security has become across industries worldwide. 

In my experience, the right free encryption software can help you secure files, messages, and disks with confidence — making it possible to protect sensitive information while keeping costs low and aligning with professional security needs

How did I find and evaluate these free encryption software?

To build this list, I began with G2 data, shortlisting top-rated tools based on their G2 scores and consistent performance in the free encryption software category.

 

From there, I reviewed product specs and recent, verified user feedback to confirm that these products deliver real value and to understand where each one stands out. 

The goal was simple: to see whether these tools are as good as they claim, what each one is best for, and whether there’s a free version or free trial you can try with minimal risk. And because this is a free-focused list, I paid extra attention to what you can actually do without paying, such as whether the free tier includes core features, how long the free trial lasts, and what limitations might prompt you to upgrade.

The screenshots featured in this article may be a mix of those taken from the vendor’s G2 page or from publicly available materials.

The product list below contains real user reviews from the best free encryption software category page. It’s important to note that in the context of this list, vendors offering a free trial are also considered free.

To be included in this category, a solution must:

  • Secure data and files using ciphertext
  • Prepare either data at rest, data in transit, or data in use for encryption
  • Allow users to choose and manage files and their encryption settings

This data was pulled from G2 in 2026. Some reviews may have been edited for clarity and accuracy.

End-to-end encrypted collaboration File reorganization is cumbersome
Strong access control options No multi-window file view
Secure sharing for teams Navigation can feel restrictive
What G2 users like about Tresorit:

“One of the main aspects of Tresorit is its robust encryption, which offers end-to-end encryption for files kept on its servers. This indicates that even if Tresorit wanted to, they cannot access the user's files; only the user has access to them. Also, its user-friendly interface makes it simple to upload, download, and share data securely.”

- Tresorit review, Deepak J.

What G2 users dislike about Tresorit:

“Reorganizing files is a pain. Much more cumbersome and visually un-intuitive than Windows File Manager. Renaming. You have to click, wait, click, wait, and often it never works. Moving files you have to go all the way up the directory and into the subfolder, sub folder, etc., which shouldn't really be necessary. You also can't open more than one window, which further necessitates following Tresorit's built in path.”

- Tresorit review, Rosi H.
