This article covers how to encrypt files offline using browser? That simply means your file is not uploaded anywhere. Everything related to encryption is done within your browser in offline mode. Later, you can decrypt the same file in offline mode using the same decryption key that you created before the encryption. For this, I am using a free service called “Hat.sh“.
The encryption process is also fast. Moreover, you can add any type of file regardless its size for offline encryption. Still, during my testing, I found that the file up to 6 GB took a lot of time for encryption. So, you can try it with some lesser size file.
In the screenshot below, you can see that I encrypted a file offline using Chrome browser and this service.
