Frequently Asked Questions
What number systems are supported?
The tool converts between hexadecimal, decimal, binary, octal, and ASCII text.
Does it convert colors?
No. This tool converts numbers and text, not colors. Use the Color Converter for hex color codes and their RGB/HSL equivalents.
How large can numbers be?
Values are processed as JavaScript numbers, so they stay accurate within the safe integer range (up to 2^53 - 1).
What is a simple conversion example?
Choose Hex to Decimal and enter FF to get 255. Use a complete value in the selected number system; this tool is not a color parser or an arbitrary-precision calculator.
What encoding tools are available?
We offer Base64 encoder/decoder, URL encoder/decoder, hash generator (MD5, SHA), XOR encoder, ROT13, Caesar cipher, and more.
Are these encoding tools free?
Yes. Every encoding tool is free and requires no account, installation, or usage limits.
Is my data secure during encoding?
All encoding and decoding happens in your browser. No data is ever sent to external servers, making it safe for sensitive information.
Do the tools support Unicode?
Character handling varies by tool. Check its documented encoding and verify a small sample before converting international text or emoji.
