Base64 encoder/decoder

Free, Open Source & Ad-free

Effortlessly encode and decode text or files to and from Base64 format with this free tool. Safe data transmission and storage in a web-friendly text format. Made with 💜 by the developers building Jam.

How to Use Jam's Base64 Decode Tool:

Paste your text and copy the result. Works for Base64 to image, Base64 to text, encoded strings, and decoding text strings back to their original binary string.

Why Encode Data?

Base64 encoding converts binary data, such as images or files, 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.
• Text to Binary Conversion:
  Converts text strings to their original binary form, useful for handling encoded text 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.
