—About Binary Converter
The Binary Converter turns text into binary and converts between binary, decimal, and hexadecimal, updating live. It is for students learning number systems and developers inspecting low-level representations.
Converting between bases by hand is slow and error-prone. Doing it locally is instant across text and numeric bases, with the input kept private.
Step by step
- Choose the conversion you want, such as text to binary or binary to hex.
- Type or paste your input.
- The converted result appears live.
- Copy the converted output.
What it offers
- Text-to-binary conversion
- Binary, decimal, and hexadecimal conversions
- Live converted output
- Converted on your device
Where it helps
- Learning how characters map to binary
- Inspecting byte values while debugging
- Converting between number bases for an assignment
- Checking a binary literal against its decimal value
Tips for best results
- Confirm the input base before converting; the same digits mean different values in different bases.
- Group binary into bytes of eight digits to read it more reliably.
- For non-ASCII text, remember the binary reflects the UTF-8 bytes, not a single code point per character.
Pitfalls to watch for
- Mixing up which base the input is in, which produces a meaningless result; set the conversion direction first.
- Forgetting that text-to-binary depends on the character encoding for non-ASCII characters.
- Reading grouped binary without spaces, where a missing digit is easy to miss.
