Base64 Encoder and Decoder
Use this free Base64 tool to encode plain text into Base64 or decode Base64 strings back into readable text. All processing takes place in your browser, making it safe for sensitive input.
Base64 encoding is commonly used for data transfer, JSON payloads, environment variables, cryptography, email attachments, and embedding binary content in text based formats.
What is Base64?
Base64 is an encoding method that converts binary data into a text based format. It uses 64 ASCII characters to represent any sequence of bytes. This makes it safe to include data inside JSON, HTML, URLs, configuration files and other systems that expect plain text.
Common questions
Why would I encode text to Base64?
Encoding makes binary or unsafe characters transportable through systems that only accept text. This is useful for APIs, environment variables, emails and scripts.
Is Base64 encryption?
No. Base64 is not encryption. It is simply an encoding method that can be decoded easily. It should not be used for protecting sensitive data.
Is my data sent to a server?
No. Everything runs entirely in your browser using JavaScript. Nothing is transmitted or stored.
