Frequently Asked Questions

What is Base64 used for?

Base64 is used to encode binary data (like images) into text so it can be embedded in HTML, CSS, JSON or transmitted via email and APIs that only support text.

Is Base64 encryption?

No. Base64 is encoding, not encryption. It converts data to a text-safe format but provides no security — anyone can decode it.
