Cryptomator is a free Windows program that encrypts your files before they leave your computer and reach a cloud drive. It is built for people who keep backups online and want the contents to stay unreadable to anyone else, including crypto users who store wallet exports or recovery notes in a synced folder.
Unlike many backup tools, it needs no registration or account, and all encryption happens locally on your PC. You can still open and edit documents directly, so the workflow feels much like working with ordinary folders. The program is also offered for macOS, Linux and mobile devices.
What Is Cryptomator and Who Is It For?
Cloud sync clients copy your files to a provider's servers, and by default that copy is readable by the provider. Cryptomator adds a layer between your files and the sync client, so what gets uploaded is ciphertext rather than your documents.
The program suits people who keep important records online but do not want them exposed. Freelancers storing invoices, families keeping scanned records, photographers with large archives and small teams sharing project folders all fit the profile. Crypto users often fall into this group too, since they may keep wallet setup notes, exchange statements or tax files that they want backed up but kept private.
Cryptomator is not a crypto wallet and does not hold coins. Its job is to protect the files around your crypto activity, not to manage funds.
How Client-Side Encryption Differs From Server-Side Encryption
Many cloud services encrypt data on their own servers, which means the company holds the means to decrypt it. Client-side encryption moves that step to your computer. The key is derived from your passphrase on your PC, and the encrypted output is what travels to the cloud.
In practice, you keep working in a normal folder while the program handles the translation. When the vault is locked, the synced copies are unreadable. When it is unlocked, the decrypted view is available only on your machine. This design matters if you are concerned about data breaches, subpoenas or simple curiosity from someone with access to the storage account.
The trade-off is responsibility. The protection is only as strong as the passphrase, and the encryption applies only to what you place inside the vault.
Realistic Use Cases for Encrypted Cloud Backups
Consider a photographer who syncs a large archive to the cloud after every shoot. Putting the archive in a Cryptomator vault means the photos remain private even if the storage account is compromised. The photographer can still open and edit raw files locally.
An accountant might keep client statements in a vault synced across two laptops. If one machine is lost, the encrypted copies in the cloud do not reveal client details to whoever finds the device. The vault is unlocked again only with the passphrase.
A crypto user might store exported transaction histories, tax summaries and screenshots of account settings in a vault. These files are sensitive even though they do not contain keys. Keeping them encrypted reduces the risk that a casual look at the cloud folder reveals a person's financial activity.

How to install Cryptomator on Windows
- 1
Download the official Windows version
Get the installer only from cryptomator.org, the official website. Avoid mirror sites and download links from search advertisements, since they may serve altered files.
- 2
Run the installer
Open the downloaded file and follow the setup wizard. Installation on Windows does not require creating an account or registering before you begin.

Create a vault in your cloud folder
Choose a folder inside your cloud client's sync directory, set a strong passphrase, and let the program create the encrypted vault. Store the passphrase somewhere safe, because losing it means losing access to everything inside the vault.
How to use Cryptomator
Using Cryptomator is straightforward once the vault exists. The routine is the same each time you back up or retrieve files, and it helps to follow it consistently.
- Open Cryptomator and select the vault you created inside your cloud folder.
- Enter your passphrase when prompted to unlock the vault.
- Wait for the decrypted drive or folder to appear, then open it like any other location on your PC.
- Copy, edit or save documents inside the unlocked vault. Changes are encrypted as they are written.
- When your work is finished, lock the vault from the program so the decrypted view is closed.
- Confirm that your cloud client has finished syncing before you shut down or switch networks.
Pros & cons
- Free to use on PC
- No registration or account required
- Encrypts both file contents and file names with AES
- Lets you edit documents locally without manual decryption
- Works across Windows, macOS, Linux and mobile platforms
- Protection depends entirely on a passphrase you must remember and keep safe
- Only files placed inside a vault are encrypted; copies stored elsewhere stay unprotected
- Does not replace a separate offline backup in case of a sync error
- Requires a cloud sync client to be set up separately for online storage
Is Cryptomator safe?
Download Cryptomator only from the official website, cryptomator.org. If checksums or signatures are published on the download page, verify the installer with SHA-256 or the signature before running it. Never enter a seed phrase, private key or wallet password on any third-party website or in a message from someone claiming to be support.
Cryptomator is encryption software, not a wallet, so it should never be asked to hold your recovery phrase. Keep seed phrases offline and out of cloud folders entirely, encrypted or not. Check the official website for the latest version before installing, and keep your operating system and antivirus up to date.
- Official source only. Download from cryptomator.org. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
Cryptomator is designed around cloud folders: it encrypts files as they sync and keeps them usable on your PC. VeraCrypt takes a different approach, using encrypted containers that you mount locally, which suits offline archives and drives rather than continuous cloud sync.
KeePassXC is a password manager for storing credentials, including logins for exchanges and wallets, so it complements Cryptomator rather than replacing it. Gpg4win focuses on PGP encryption and signatures, which many users rely on to verify installers. For checking the integrity of downloaded files, 7-Zip and certutil are useful for computing SHA-256 hashes.
If you need a person to recover access to a lost wallet, a paid service such as Wallet Recovery Services addresses a different problem altogether.

Frequently asked questions
Yes, Cryptomator is free to use on PC, including the official Windows version. There is no registration or account needed to start encrypting files. Download the program from the official website to be sure you are getting the genuine installer.
Cryptomator is designed to encrypt files locally with AES before they reach cloud storage, which reduces exposure if the storage is accessed by others. Its safety depends on downloading from the official site, verifying the installer, and choosing a strong passphrase. It cannot protect files you never place in a vault.
No, Cryptomator does not require registration or an account. All encryption takes place on your own computer, so your data is not handled by a Cryptomator service during normal use. You only need the program and a folder your cloud client syncs.
Cryptomator works with any cloud storage that syncs a folder to your PC. You create the vault inside that synced folder, and the sync client uploads the encrypted files. The exact setup depends on which sync client you use, so follow its instructions for the folder location.
No, Cryptomator is not a crypto wallet and does not store coins or manage transactions. It encrypts ordinary files, such as statements or records related to your crypto activity. Seed phrases and private keys should never be placed in a vault that is synced to the cloud.
Access to a Cryptomator vault depends on its passphrase, so forgetting it can lock you out of the encrypted files. Treat the passphrase like the master secret it is, and store it in a secure password manager or offline location. Plan for this before you start relying on the vault.
Verdict
Cryptomator suits people who want a free, account-free way to encrypt files before they reach cloud storage on Windows. It is most useful for documents, photos and records that you need to edit regularly, and for crypto users who keep related paperwork online. It is not a substitute for a wallet, a separate offline backup or good passphrase habits. If you already sync folders to the cloud and want privacy without extra accounts, it is a practical choice to evaluate.
