FAQs

What is Base64 encoding?

Base64 is an encoding scheme that converts binary data (such as images or non-ASCII text) into an ASCII string format. It uses 64 characters (A-Z, a-z, 0-9, +, /) and '=' for padding.

Why use Base64?

Base64 is commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data. This ensures that the data remains intact without modification during transport, such as embedding images in HTML/CSS.

Is Base64 secure encryption?

No. Base64 is encoding, not encryption. It provides no security. Anyone can easily decode a Base64 string back to its original form. Do not use Base64 to hide passwords or sensitive data.
