Enter hex numbers with any prefix / postfix / delimiter and press the Convert button
(e.g. 45 78 61 6d 70 6C 65 21):
ASCII text encoding uses fixed 1 byte for each character.
UTF-8 text encoding uses variable number of bytes for each character. This requires delimiter between each hex number.
Please note: any spaces or colons (:) in the hexadecimal string will be removed.
Need to convert text to hex?
Hexadecimal notation is used as a human-friendly representation of binary values in computer programming and digital electronics. Most programming languages such as Java, ASP.NET, C++, Fortran etc have built-in functions that convert to and from hex format.

What is a Hexadecimal?
Most people are familiar with the decimal, or base-10, system of numbers (all possible numbers can be notated using the 10 digits, 0,1,2,3,4,5,6,7,8,9). With only 10 digits, extra digits need to be used at certain intervals to correctly notate a number. For example, the number 423,004 uses twice as much digits as the number 961.
The hexadecimal, or base-16, system was created to emulate some of the same properties of the common decimal system. The overall difference is, 16 digits are available instead of the 10 digits available to use to notate the value of a number.
The 16 symbols that the hexadecimal system uses are: 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E and F. So instead of a decimal symbol of 10, hexadecimal uses an A, and so on and so forth until we get to the decimal of 15 which is notated as F. Similar to the decimal system, after the base of 16 symbols has been used, the appropriate extra digit is added and the order of numbers starts over. In other words, after F, we begin with 10, and so on. To better understand the relationship between the Decimal and Hexadecimal system, check out the table below.
What is a Hexadecimal Encoding in Programming?
Hexadecimal encoding is used by programmers to improve readability of bytes, which are used to communicate to computers. There are a number of benefits for using hexadecimal encoding, including the the higher information density available, as hexadecimal encoding effectively reduces 8 digits of binary code to 2 hexadecimal digits. With this effect, 2 hexadecimal digits expresses any number from 0 to 255, the same scope of numbers as binary’s 8 digits.
Hex Encoding vs. Base 64
While Encoding in Hex is a popular encoding strategy used by progammers, Hex encoding does significantly increase the space used of storage, which reduces the efficiency of your communication with the computer. If storage space is an issue, encoding in Base 64 is recommended as an alternative.
What Is Hex Encoding Used For?
The reasons for using hex encoding are basically the same as for Base64 encoding — it’s used for when you want to send or store 8 bit data on a media that only accepts 6 or 7 bits. Hex encoding is performed by converting the 8 bit data to 2 hex characters. The hex characters are then stored as the two byte string representation of the characters.
Often, some kind of separator is used to make the encoded data easier for human reading. With 8 bits converted to three characters and each character stored as 1-4 bytes you might use up to 12 bytes (or even more in some cases) for each byte of information.
Again, don’t use hex encoding if storage space is an issue. The encoding is quite easy to read though, so if human readability is an issue, then hex encoding is probably a better choice than base64 encoding.

About Hex to ASCII String Converter Online Tool:
This online Hex to ASCII string converter tool helps you to convert one input Hex string (base 16) into a ASCII String.
The accept Hex string delimiters include («», » «, «0x», «0X», «x», «X», «x», «X», »

Hex Numeral System:
Hex numeral system (also called hexadecimal) has 16 digits, include (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) just like decimal numeral system, plus (a, b, e, d, e, f) 6 additional characters. Which means it’s is a number system of base 16. Since Hex numeral system can represent any binary string in a readable way, It is widely used in computer science. The SHA256 hash string is often appears as Hex style string, the Color System used in HTML is also be written down as Hex number, from #000000 (pure black) to #FFFFFF (pure white).
ASCII Encoding Standard:
ASCII (American Standard Code for Information Interchange) is the most widely used character encoding standard. The standard ASCII has 7 bits, 128 distinguish characters. The extended ASCII has 8 bits, 256 distinguish characters. The Copyright Symbol © that you see everyday is in the extended ASCII list.
