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.
