Frequently Asked Questions

What encoding formats are supported?

The tool supports 8 formats: Binary (base-2), Hexadecimal (base-16), Octal (base-8), Morse Code, ROT13 (Caesar cipher), URL Encoding (percent encoding), HTML Entities, and Reverse Text. Each format can both encode and decode.

How does Morse code encoding work?

Each letter and number is converted to its standard International Morse Code representation using dots (.) and dashes (-). Letters are separated by spaces, and words are separated by ' / '. The tool supports A-Z, 0-9, and common punctuation marks.

What is ROT13?

ROT13 is a simple letter substitution cipher that replaces each letter with the letter 13 positions after it in the alphabet. It's its own inverse - applying ROT13 twice returns the original text. It only affects letters; numbers and symbols are unchanged.

Does encoding happen in real time?

Yes. The output updates instantly as you type in the input field. There's no submit button - the conversion is live. This makes it easy to experiment and see results immediately.

Is my text sent to a server?

No. All encoding and decoding happens entirely in your browser using JavaScript. No data is transmitted anywhere. The tool works completely offline once the page is loaded.

Is this tool free?

Yes, completely free with no signup required. No limits, no ads, no hidden fees.
