Introducing our free web tool, the Base64 Decoder! This powerful online tool is designed to effortlessly convert Base64 to Text and vice versa, making it a must-have utility for developers, data analysts, and anyone dealing with encoded data. With its user-friendly interface and instant results, the Base64 Decoder streamlines the process of working with Base64-encoded data.

Base64 encoding is commonly used to convert binary data into a textual format, making it easier to handle and transmit across various systems. However, when working with Base64-encoded data, it can be challenging to read and interpret the information directly. This is where the Base64 Decoder proves its worth, as it allows users to effortlessly decode Base64 strings and instantly translate them into human-readable text.

The tool offers two-way functionality, allowing users to not only decode Base64 strings but also encode plain text into Base64. This versatility ensures users can seamlessly switch between the two formats as per their requirements.

The web tool boasts a simple and intuitive user interface, making it accessible to both beginners and experienced users. No technical expertise is needed, making the process smooth and hassle-free.

The Base64 Decoder operates on a straightforward principle. When a Base64 string is pasted into the input field, the tool analyzes the encoded data and decodes it according to the Base64 algorithm. The resulting plain text is then displayed in the output field. Users can copy the decoded text for further use or even utilize the tool to encode plain text into Base64, simply by switching the input and output fields.

The Base64 Decoder serves as an invaluable web tool for swiftly translating Base64 data into a readable format, enhancing efficiency and productivity in working with encoded data. Its instant conversion, ease of use, and bi-directional functionality make it a go-to resource for anyone dealing with Base64-encoded information on the web. Whether you're a developer, data analyst, or simply someone handling encoded data, the Base64 Decoder is an essential addition to your toolkit.

Here is an example of how to encode and decode Base64 in Python, PHP, Java, NodeJS and C++:


import base64

# Encoding
data = b'hello world'
encoded_data = base64.b64encode(data)

# Decoding
decoded_data = base64.b64decode(encoded_data)


⁄⁄ Encoding
$data = 'hello world';
$encoded_data = base64_encode($data);
echo $encoded_data;

⁄⁄ Decoding
$decoded_data = base64_decode($encoded_data);
echo $decoded_data;


import java.util.Base64;
⁄⁄ Encoding
byte[] data = "hello world".getBytes("UTF-8");
String encodedData = Base64.getEncoder().encodeToString(data);

⁄⁄ Decoding
byte[] decodedData = Base64.getDecoder().decode(encodedData);
String decodedString = new String(decodedData, "UTF-8");


const base64 = require('base64-js');

⁄⁄ Encoding
const data = Buffer.from('hello world');
const encodedData = base64.fromByteArray(data);

⁄⁄ Decoding
const decodedData = base64.toByteArray(encodedData);


#include <iostream>
#include <sstream>
#include <iomanip>
#include <string>
#include <vector>
#include <algorithm>

#include "base64.h"

using namespace std;

⁄⁄ Encoding
string data = "hello world";
string encoded_data = base64_encode(reinterpret_cast<const unsigned char*>(data.c_str()), data.length());
cout << encoded_data << endl;

⁄⁄ Decoding
string decoded_data = base64_decode(encoded_data);
cout << decoded_data << endl;
