Frequently Asked Questions

KeySwap is a free online tool that converts text typed with the wrong keyboard layout back to the intended language. For example, if you accidentally typed in Thai when you meant to type in English, KeySwap can instantly convert your text.

Every key on your keyboard has a specific position. Different languages map different characters to each position. When you type with the wrong layout active, KeySwap maps each character back to what you intended by matching keyboard positions between layouts.

KeySwap currently supports: Thai (Kedmanee), Russian (ЙЦУКЕН), French (AZERTY), German (QWERTZ), Japanese (Romanji/Hiragana), and Korean (Dubeolsik). All layouts convert to and from English QWERTY.

No. KeySwap operates 100% in your browser (client-side). Your text is never sent to any server, never stored, and never logged. We have no access to what you type or convert. Your privacy is completely protected.

Yes! KeySwap is completely free with no registration required, no usage limits, and no hidden fees. We support the service through minimal, non-intrusive advertising.

Absolutely! KeySwap is fully responsive and works on any device with a modern web browser, including smartphones, tablets, laptops, and desktop computers.

KeySwap uses bidirectional conversion, meaning it will convert characters that can be mapped and leave others unchanged. This works well for mixed-language text, though results are best when the majority of your text is from one layout.

This commonly happens when: (1) You forget to switch your system keyboard language, (2) A keyboard shortcut accidentally changes your layout (like Alt+Shift on Windows), or (3) You're working quickly and don't notice the wrong layout is active until you look up at the screen.

On Windows: Press Alt + Shift or Win + Space. On Mac: Press Ctrl + Space or Cmd + Space (if configured). On Linux: Usually Super + Space or check your system settings.

Yes! Simply copy your text from any document, paste it into KeySwap, and the converted result will appear instantly. You can then copy the result back to your document. There's no limit to the amount of text you can convert.
