Base64 Encode

Base64 encoding is a method used to convert binary data—such as images, files, or plain text—into ASCII string format. It’s commonly used in web development, email formatting, and data transmission where only text-safe characters are allowed. By converting data into a base-64 representation, you ensure that it remains unaltered during transport across systems that may not support binary formats.

Encode to Base64 Format

Base64 Encoder allows you to upload and convert files—such as images, PDFs, or documents—into Base64 format using our online tool. Base64 Encoding is particularly useful for embedding email attachments, web-based assets, and cryptographic data directly into HTML, CSS, or JSON.

Ensures accuracy and efficiency

Whether you need to encode to Base64-encoded files for development, storage, or security purposes, this tool ensures accuracy and efficiency.

Common Base64 Use Cases

Base64 Decode
Email attachments
(MIME format) – Email systems encode files in Base64 to ensure proper transmission and display. This combination leaves the data unlikely to be modified in transit through systems such as email, which were traditionally not 8-bit clean. Web developers use Base64 encoding to embed images and media directly into HTML or CSS files.
Base64 Decode
Cryptographic applications
Base64 encoding schemes help store hashed passwords, digital signatures, and secure keys in Base64 format. Also, for Secure File Transfers. Many systems encode sensitive files in Base64 before transmission to maintain integrity.
Base64 Decode
Encoded data reamins intact
URL-Safe Encoding, it converts + to - and / to _ to prevent issues in URLs. Also, spaces and special characters are encoded as %20 for better compatibility in web links.It also ensures that encoded data remains intact when used in links, APIs, and other web-based environments.
Base64 Decode
Printable characters
Base64 uses a set of printable characters to represent binary data, but in web development, some characters require special handling. Also for Standard Characters: Uses A-Z, a-z, 0-9 for the first 62, +, / for encoding.

Base64 Encode Functions

Base64 encoding is supported natively or through libraries in most programming languages.
Here's how it’s typically implemented:

JavaScript
// JavaScript

//The btoa() function decodes Base64 strings in web applications.

const encodedString = btoa("Some encoded string");
console.log(encodedString); // Output: U29tZSBlbmNvZGVkIHN0cmluZw==
Base64 Decode
# Python
# The base64.b64decode() function converts Base64 text into its original binary format.
import base64
original_str = "Some encoded string"
encoded_bytes= base64.b64encode(original_str.encode("utf-8"))
print(encoded_str)  # Output: U29tZSBlbmNvZGVkIHN0cmluZw==
Base64 Decode
// PHP
// The base64_decode() function allows web developers to process encoded data.
$encoded_str = "U29tZSBlbmNvZGVkIHN0cmluZw==";
$decoded_str = base64_decode($encoded_str);
echo $decoded_str; // Output: Some encoded string
Base64 Decode
// Java
// The Base64.getEncoder().encodeToString() method efficiently encodes text into Base64.
import java.util.Base64;
public class Main {
    public static void main(String[] args) {
        String originalStr = "Some encoded string";
        String encodedStr = Base64.getEncoder().encodeToString(originalStr.getBytes());
        System.out.println(encodedStr); // Output: U29tZSBlbmNvZGVkIHN0cmluZw==
    }
}
Base64 Decode
// C#
// The Convert.ToBase64String() method encodes binary data into a Base64 string.
using System;
class Program{
   static void Main()
   {
       string original = "string"; // Original string to encode
       byte[] bytes = System.Text.Encoding.UTF8.GetBytes(original); // Convert string to bytes
       string encoded = Convert.ToBase64String(bytes); // Encode bytes to Base64
       Console.WriteLine(encoded); // Output: c3RyaW5n
   }
}
Base64 Decode
# Ruby
# The Base64.encode64() method encodes a string into Base64 format.
require 'base64'original = 'string'  # Original string to encode
encoded = Base64.encode64(original)  # Encode string to Base64
puts encoded  # Output: c3RyaW5n
Base64 Decode
-- MySQL
-- The TO_BASE64() function encodes a string into Base64 format.
SELECT TO_BASE64('string') AS encoded; -- Output: c3RyaW5n
Base64 Decode
-- PostgreSQL
-- The encode() function encodes binary data using the specified format, like 'base64'.
SELECT encode('string'::bytea, 'base64') AS encoded; -- Output: c3RyaW5n
Base64 Decode
# Linux CLI
# The base64 command encodes input into Base64 format.
# The -n flag prevents echo from adding a newline character.
echo -n 'string' | base64  # Output: c3RyaW5n
