Base64 encoder/decoder

Use this free Base64 encoder and decoder to easily convert between plain text and Base64-encoded strings. This tool is perfect for decoding API responses. No need to sign up — just paste your data and convert instantly. Made with 💜 by the developers building Jam.

How to Use the Base64 Decode Tool:

You can use this tool to decode Base64-encoded strings, or to convert Base64 text strings back to their original binary string. Just paste your data and copy the result. If you need to convert images to Base64 you can use this tool.

Use Cases:

• Data Conversion: Convert text strings to their original binary form, useful for handling encoded text data.
• Debugging: Decode Base64 data when troubleshooting or analyzing web resources.

How Does the Base64 Tool Work?

Base64 encoding converts binary string into a text format that can be safely transmitted over text-based protocols like HTTP, email, and more. This process ensures that the data remains intact and prevents corruption during transmission.

• Data Integrity:
  Ensures that binary data, special characters, and non-ASCII symbols are correctly transmitted over the internet without corruption.
• Data Embedding:
  Allows embedding binary data within text-based formats like JSON, XML, and HTML, making it useful for web applications and APIs.
• Compatibility:
  Facilitates easier data sharing and exchange between different systems and platforms that handle text-based data.
• ASCII Decoding:
  Converts ASCII strings back to their original binary form, ensuring accurate data reconstruction.

Using Base64 in JavaScript:

In JavaScript, Base64 encoding and decoding can be done using the built-in btoa and atob functions.

let text = "Hello, world!";
let encoded = btoa(text);
console.log(encoded); // Outputs: "SGVsbG8sIHdvcmxkIQ=="

let encoded = "SGVsbG8sIHdvcmxkIQ==";
let decoded = atob(encoded);
console.log(decoded); // Outputs: "Hello, world!"

These functions make it easy to handle encoding and decoding directly within your JavaScript code, enabling smooth data processing and transmission in web applications.
