Base64 Encoder / Decoder

About Base64 Encoder / Decoder

Overview

Our Base64 Encoder and Decoder allows you to instantly convert plain text strings or raw data into Base64 format and vice versa. Base64 encoding represents binary data in an ASCII string format, making it safe to transmit over protocols that only support plain text, like URL queries or email headers.

🔒 Privacy & Security Guarantee

All encoding and decoding scripts execute entirely in-memory. Since credentials or sensitive API key structures are often Base64-encoded, using our client-side utility protects your raw credentials from being exposed in server access logs.

Frequently Asked Questions

What is the '=' character at the end of some Base64 strings?+

The '=' symbol is a padding character. Base64 operates on blocks of 3 bytes (24 bits). If the input data is not a multiple of 3 bytes, padding characters are appended to the end of the encoded string to satisfy alignment.

Does Base64 encode secure my data?+

No, Base64 is NOT encryption. It is a simple encoding scheme. Anyone can easily decode a Base64 string back to its original value using standard tools.
