Frequently Asked Questions
What is the Binary Converter?
Binary Converter is an online tool that encodes text to binary representation and decodes binary strings back to text. It runs entirely in your browser with no data sent to any server.
How does the binary encoding work?
Each character is converted to its 8-bit binary representation using its character code. For example, the letter 'A' (code 65) becomes 01000001. The output is space-separated for readability.
What format should I use when decoding binary?
You can paste binary with or without spaces between each 8-bit group. The decoder ignores all whitespace and processes the binary string in 8-bit chunks from left to right.
Is my data safe when using the Binary Converter?
Absolutely. All encoding and decoding happens locally in your browser. No data is uploaded to any server, ensuring your information remains completely private and secure.
Can I use the Binary Converter on my phone?
Yes, the Binary Converter is fully responsive and works on all devices including smartphones, tablets, and desktop computers. On smaller screens the input and output panels stack vertically.
