7-Zip vs Cryptomator

7-Zip is a file archiver for Windows, Linux, and macOS, offered at free with no registration or payment required. It creates and extracts 7z, XZ, BZIP2, GZIP, TAR, ZIP, and WIM archives, and can extract additional formats such as RAR, ISO, and VHDX. The 7z format uses LZMA and LZMA2 compression, and AES-256 encryption is available for 7z and ZIP files. Other listed capabilities include split archives, archive repair, portable use, and command-line tools. The Windows version includes Shell integration, a file manager, a command-line version, and a FAR Manager plugin. The software is open source; most code is under the GNU LGPL, with some under BSD licenses and an unRAR restriction applying to some parts. The maker says it can be used in commercial organizations without payment. It is localized in 87 languages. Developers can use the LZMA SDK, which includes documentation, samples, headers, libraries, and tools for applications using LZMA compression.

Cryptomator encrypts files on the user's device before they go to a cloud storage service. Its AES encryption uses a 256-bit key and covers both file contents and filenames. The software is open source, with source code available for community security audits. It works with a cloud service of the user's choice; on desktop, access to vaults requires that service's sync software on the computer. Mobile apps natively support services such as Dropbox, Google Drive, OneDrive, pCloud, S3, and WebDAV, with availability varying by platform. The Android and iOS apps are currently incompatible with Mega, including through WebDAV. Free mobile versions are read-only; full access requires a separate one-time purchase for each platform. Cryptomator Hub adds user and group administration and zero-knowledge key management for teams, with OpenID Connect, SAML, and LDAP integrations. Cryptomator lists Android, iOS, Linux, macOS, web, Windows, and self-hosted platforms. The individual plan is free; optional upgrades are €29.99, paid once.
