Welcome to the Easy Converters ASCII, Hex, Binary, Decimal, Base64 Converter – your comprehensive tool for instant conversion between multiple text encoding formats. Whether you're a developer, student, cybersecurity analyst, or just curious about how data is represented behind the scenes, this free online converter is your go-to utility for seamless transformations between numeric and character formats.
This tool allows you to convert between the five fundamental data formats used in computer science and digital systems:
Enter a value in any one of the fields (ASCII, Hex, Binary, Decimal, or Base64), and the converter will instantly update all other fields with the corresponding values. No page refresh, no complexity—just clean, immediate results.
Base64 takes binary data and encodes it using 64 printable ASCII characters. It ensures safe data transfer over channels that may misinterpret binary or control characters. It's often seen in:
No. Base64 is an encoding format—not encryption. It can be reversed without a key, unlike encryption methods.
Yes, you can decode the payload of JWT tokens (Base64-encoded), though the signature part will remain unreadable without a secret key.
Hex is more compact—one hex digit represents four binary bits, making it easier to read and debug.
This tool primarily handles ASCII characters. For full Unicode or UTF-8 support, use a Unicode-aware encoding tool.
Absolutely. It’s tailored for developers, cybersecurity experts, system engineers, and students working with text, data, or encodings.
Understanding how data is represented internally by computers is essential for any technical role. Whether you're handling raw data streams, building compilers, creating efficient algorithms, or working with embedded devices, knowledge of ASCII, binary, hex, decimal, and Base64 provides the foundation.
Encodings are not just theoretical—they’re embedded into everyday technologies like SMS, HTTP, machine instructions, and even your browser rendering this page. Grasping the relationships between these formats helps you make sense of how computers store, process, and transmit data.
ASCII is the oldest and most fundamental character encoding scheme. It maps 128 characters (letters, digits, punctuation, and control codes) to values between 0 and 127. These include familiar characters like:
Binary is a base-2 number system composed only of 0s and 1s. Each bit (binary digit) represents a power of 2. Computers store everything in binary—from characters to images to videos. For example, the character 'A' in binary is 01000001, which corresponds to decimal 65.
Decimal (Base-10) is the number system used in daily life. While machines work in binary or hex, decimal is often used in documentation or debugging logs to help humans interpret values. For instance:
Hex (Base-16) is widely used in programming, memory addressing, and color representation in web design. It uses digits 0–9 and letters A–F. One hex digit represents four binary bits, which makes it a more compact way to express binary data. Examples:
41 = ASCII 'A' = Decimal 657F = ASCII 'DEL'20 = SpaceBase64 is an encoding system designed to transfer binary data through channels that only support text, such as emails, HTML, or HTTP headers. It converts groups of 3 bytes (24 bits) into 4 ASCII characters. Base64 ensures that non-textual data can be safely encoded and decoded across systems without corruption.
While Base64 is not an encryption method, it is heavily used in cybersecurity contexts. Many malware payloads, email phishing attacks, and obfuscated data use Base64 to hide or transport code. Learning to decode and recognize Base64 patterns is vital for security professionals and analysts.
It’s important to distinguish between character encodings (ASCII, UTF-8) and numeric encodings (binary, hex, decimal). Character encodings define how text maps to byte sequences, while binary/hex/decimal are the numeric representations of those bytes. This converter bridges both aspects by showing how ASCII characters become numbers and how numbers represent characters.
Understanding encoding systems is critical in system-level programming, especially when memory or bandwidth is limited. For example:
| ASCII | Binary | Decimal | Hex | Base64 |
|---|---|---|---|---|
| A | 01000001 | 65 | 41 | QQ== |
| a | 01100001 | 97 | 61 | YQ== |
| 0 | 00110000 | 48 | 30 | MA== |
| ! | 00100001 | 33 | 21 | IQ== |
\n (LF), \r (CR), and \t (TAB) are encoded in ASCII but interpreted by programming languages as formatting instructions.Our converter is designed with accessibility in mind. It works across all modern browsers, including mobile devices. You can paste long strings or even paragraphs and see the character-by-character encoding. The input boxes automatically resize to fit your text, and each conversion is triggered in real-time without delay or reloads.
Encoding formats like ASCII, Hex, Binary, Decimal, and Base64 are not just academic—they power countless real-world technologies. Let’s explore how they’re applied across industries and applications:
Let’s look at how different programming languages represent and convert between formats:
# Convert character to ASCII
ord('A') # 65
# Convert ASCII to character
chr(65) # 'A'
# Base64 encoding
import base64
base64.b64encode(b'Hello') # b'SGVsbG8='
// ASCII code of character
'A'.charCodeAt(0); // 65
// Character from ASCII
String.fromCharCode(65); // "A"
// Base64 encode
btoa('Hello'); // 'SGVsbG8='
char c = 'A';
int ascii = (int)c; // 65
char back = (char)65; // 'A'
Every character you type on a keyboard is stored as a series of bits—fundamental units of data in computing. For example, the character 'B' has the following representations:
Understanding these representations helps in data compression, transmission, and even designing your own encoding schemes in networking or game engines.
Many everyday tools you use rely heavily on encoding and conversions:
