What is Base64?

Base64 is an encoding scheme that converts binary data into an ASCII string format by translating it into a radix-64 representation. It is commonly used when there is a need to encode data that needs to be stored and transferred over media that are designed to deal with textual data. This helps ensure that the data remains intact without modification during transport.


Is it secure?

Base64 is an encoding method, not a cryptographic encryption. It provides no security or privacy if intercepted. However, using this tool is completely safe because the encoding/decoding is performed client-side via JavaScript. Your text never leaves your computer.

Frequently Asked Questions

Is Base64 encoding the same as encryption?
No. Base64 is simply a translation scheme to make binary data text-readable. Anyone can decode it, so never use Base64 to hide sensitive passwords.
Can I convert an image into a CSS Data URI?
Yes! By Base64 encoding your image file, you can embed it directly into your CSS or HTML src attribute, eliminating an extra HTTP request.
Why does my Base64 string end with equal signs (=)?
Those are padding characters. Base64 processes data in 24-bit chunks, and the = signs fill out the final chunk if the input doesn't divide perfectly.
