Frequently Asked Questions

What is Base64 encoding?

Base64 is an encoding scheme that converts binary data (or text) into a string of ASCII characters. It is commonly used to embed binary data in text formats like JSON, XML, HTML, and email attachments.

Is Base64 encryption?

No. Base64 is encoding, not encryption. It can be easily decoded by anyone. Never use Base64 to protect sensitive data — use proper encryption (AES, RSA) for that.

Why does Base64 output end with = signs?

Base64 encodes 3 bytes into 4 characters. If the input is not a multiple of 3 bytes, padding characters (=) are added at the end. One = means 1 byte of padding, == means 2 bytes of padding.
