Your Files Are Uploaded for Base64

Problem

Every time you need to encode a file or image to Base64, you have to upload it to an online tool. You can't be sure if the server stores or shares your data. For sensitive files, you're forced to write your own script or use a local tool that may not handle all formats correctly.
