Free numeric converter: convert from binary to decimal, hexadecimal, octal and more
Discover the best way to convert numbers between numeric systems easily. Your figures in the numeric language you need without paying and without waiting!
The search for an online numeric systems converter is very recurrent because it's not the type of utility we want to have on our device taking up space and slowing down the system, right? It's much more appropriate to access a free online number conversion system, that respects anonymity and allows you to convert numeric bases instantly, just by entering a figure (literally).
Numeric converter features
How is our number converter?
- Multi-base conversion. Our converter includes binary, decimal, hexadecimal, quaternary, quinary and octal numeric systems. You can enter and get your figure in any of them. Thus, this will be your binary to decimal number converter, decimal to hexadecimal and all possible combinations between these six numeric languages.
- Instant conversion. Your figures are translated to their equivalent in another numeric base at the same moment you enter them. You don't have to press buttons or wait.
- Secure online numeric conversion. You can translate any figure as long as you have access to our site, without installing any program or app on your device. You only need internet connection and save devtools.com in favorites.
- Privacy. We don't obtain any personal data, you don't need to register and even your history disappears as you close our tool window. There's no trace of your site access or your activity left.
How to convert numbers between different numeric bases with our tool?
The online numeric conversion system we offer couldn't be simpler:
- In the left box, above, choose which base you're using, that is, the one in which the figure you're going to enter is expressed.
- Just below, enter the number you want to convert. If you want to enter several figures at once, they must be separated by a semicolon (;).
- By default, the converter will translate the figures to the destination base that is selected (right box). You must change it to the one that interests you. The conversion is immediate.
- If you wish, you can copy the result from the post-it button that is just to its right.
What are numeric systems or numbering systems?
Numeric systems are ways to create and represent numeric data, including both symbols and rules. It's something like the equivalent of language. Two systems represent the same numeric data differently, just like we do, for example, in Spanish and English.
The traditional numbering system, the one we learn at school and the one we use daily to communicate is the decimal system. However, there are many others, among which we highlight hexadecimal, binary, quaternary, quinary and octal.
Each of them offers a way to represent numeric data, which may be more or less suitable depending on the case.
Available numeric systems:
- Binary System (Base 2): For example, binary is the language of computers and, nowadays, of the rest of intelligent devices.
- Octal System (Base 8): Octal is also used in computing, in certain aspects, for being bases with exact powers of the binary system. The most representative (and we find it in everyday life) is the way of classifying bits, in packets of 8. When we go from GB to MB we have that 1 GB equals 1024 MB, not 1000, as decimal logic would be. And how much is 1024? Exactly: 8^5.
- Hexadecimal System (Base 16): Hexadecimal, on the other hand, is used to work with immense numbers, as in this aspect, it is more effective: you need fewer digits, that is, shorter numeric sequences. In this system we find color codes.
- Decimal System (Base 10): The traditional numbering system, the one we learn at school and the one we use daily to communicate.
- Quaternary System (Base 4): Base 4 system that uses only four different digits to represent all numbers.
- Quinary System (Base 5): Base 5 system that uses five different digits to represent all numbers.
Numeric bases are the number of digits used to represent all numbers in a system. I'm sure you already know but binary is a base 2 language, as it only uses two different digits (0 and 1) to represent all numbers. The decimal system is base 10 (from 0 to 9), hexadecimal is base 16, octal is base 8 and quinary is base 5.
What is a numeric converter?
It's a tool or utility that allows you to transfer figures between different numeric systems (binary, decimal, hexadecimal, octal, quaternary and quinary in our case). In other words, we have a number expressed in one system and we "translate" it to another. The value is the same but the way to represent it is different.
It ranks at the top of online mathematical tools, being one of the most sought after for the versatility of uses it can have.
What numeric system should I use?
Indeed, you will encounter a different numeric representation, to choose according to needs.
- Programming and hardware development use hexadecimal and decimal.
- Electronics, engineering and video game development more commonly use hexadecimal and binary.
- In general computing the language par excellence is binary.
- In finance and chemistry we maintain the decimal system.

Frequently Asked Questions
This is a tool to convert hexadecimal, decimal, binary, quaternary, quinary and octal numbers, between any of them.
Currently our converter is optimized for positive integers, which are the most used in conversions between numeric bases.
It's simple. Do a cross-check between several bases to end up, again, in the one that interests you; you'll see that it matches.
The limit is set by the systems you want to use. If it can be expressed in any of the available bases, our numeric converter will do it.
Yes, although they must belong to the same numeric language system. The way for the number converter to detect that you're entering several figures is by separating them with a semicolon (;).
Nothing. This is an application to convert numbers between bases of instantaneous character. In fact, it's a reactive system that performs the conversion at the same time you enter the figures, with immediate result.
Our utility allows you to make a quick copy, by pressing the button right next to the converted figures, ready for you to paste wherever you need. You can also make a traditional copy (selecting the result and pressing CTRL + C).
No. With our online tool for number conversion you don't have and we don't have access to a history. What you can do is copy (you have a button for it), each figure that is generated so you can use them whenever you want.
Yes. Our conversion tool between bases doesn't make calls to external services, doesn't ask for data or force you to download anything. It simply runs in your browser window. When you close it, all traces disappear, both the information you worked with and your own. Nobody has access to it either after the session or while you remain on our site.
