What is Base64?
Base64 encodes binary or text data into a safe set of characters so it can travel through systems that only handle text — like embedding images in CSS, sending data in URLs, or storing tokens. It is encoding, not encryption, so it isn't a way to secure secrets.
Frequently asked questions

Is my text uploaded?
