Free Online Base64 Encoder
Encode or decode Base64 strings with our simple and efficient online tool.
What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. It is commonly used to encode data for storage or transmission over media that are designed to deal with textual data. This ensures that the data remains intact without modification during transport. The name comes from the fact that it uses 64 basic ASCII characters to represent the data.
How does Base64 work?
Base64 works by taking the binary data, breaking it into 3-byte (24-bit) chunks, and then remapping these chunks into 4 new 6-bit chunks. Each of these 6-bit chunks is then mapped to one of 64 ASCII characters. The character set typically includes A-Z, a-z, 0-9, and two other characters, usually '+' and '/'. If the last group of bytes is less than 3 bytes, padding is added to make the output a multiple of 4.
Why Use Our Base64 Encoder/Decoder?
Our online Base64 tool provides a simple, fast, and reliable way to encode and decode data. Whether you're a developer needing to encode credentials, a data analyst working with text, or anyone who needs to handle Base64 data, our tool is designed for efficiency and ease of use. All operations are performed locally on your device, ensuring your data remains private and secure.
How to use the tool
To encode, simply type or paste your text into the input field and the encoded output will appear in real-time. To decode, paste the Base64 string into the input field and the original text will be displayed. Use the toggle to switch between encoding and decoding modes.
Security and Privacy
We prioritize your privacy. All encoding and decoding operations are performed locally in your browser. This means your data is never sent to our servers, ensuring complete security and confidentiality.
Disclaimer
We do not take any responsibility for the encoded or decoded data or its usage. All operations are performed on your device, and the application of the output is solely at your discretion and risk.
