Benefits of Using Base64 Encoder

Data Encoding

Encode binary data or text into Base64 format for safe transmission over text-based protocols.

API Integration

Essential for working with APIs that require Base64-encoded data, such as image uploads or file transfers.

Data Storage

Encode data for storage in databases or configuration files that only accept text.

Privacy First

All encoding and decoding happens locally in your browser. Your data never leaves your device.

Key Features

Encode text to Base64

Decode Base64 to text

Support for binary data

API-ready format

Works entirely offline

Free to use with no limitations

How to Use

Enter Your Text

Type or paste the text you want to encode or decode into the input field.

Choose Action

Click "Encode" to convert text to Base64 format, or "Decode" to convert Base64 back to text.

Copy Result

Copy the encoded or decoded result and use it in your applications or APIs.

Understanding Base64 Encoding and Decoding

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 binary data, especially when that data needs to be stored and transferred over media that are designed to deal with textual data.

Our free Base64 encoder/decoder tool helps developers encode and decode Base64 strings instantly. This is essential for working with APIs, data storage, and file transfers that require text-based encoding.

Why Base64 Encoding is Used

Data Transmission: Enables safe transmission of binary data over text-based protocols like HTTP, email, and XML.
Data Storage: Allows binary data to be stored in text-only formats like JSON, XML, or databases.
API Integration: Many APIs require Base64-encoded data for image uploads, file transfers, and data exchange.
Email Attachments: Email systems use Base64 encoding for binary attachments.

Common Base64 Use Cases

Image encoding for data URIs
API file uploads
Email attachment encoding
Database storage of binary data
Configuration file encoding

All Base64 encoding and decoding happens locally in your browser, ensuring complete privacy and security for your data.

Code Examples

Base64 Encoding Example

Original: Hello World!
Encoded: SGVsbG8gV29ybGQh

Original: Internative
Encoded: SW50ZXJuYXRpdmU=

JavaScript Base64 Encoding

// Encode
const encoded = btoa('Hello World!');
// Result: SGVsbG8gV29ybGQh

// Decode
const decoded = atob('SGVsbG8gV29ybGQh');
// Result: Hello World!

Base64 Image Data URI

data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mNk+M9QDwADhgGAWjR9awAAAABJRU5ErkJggg==

Node.js Base64 Encoding

const Buffer = require('buffer').Buffer;

// Encode
const encoded = Buffer.from('Hello World!').toString('base64');
// Result: SGVsbG8gV29ybGQh

// Decode
const decoded = Buffer.from('SGVsbG8gV29ybGQh', 'base64').toString();
// Result: Hello World!
