Thai ⇄ English Keyboard Layout Fixer

Ever typed a whole sentence only to find your keyboard was in the wrong language? "l;ylfu" instead of "สวัสดี", or a burst of Thai when you meant English? This free tool fixes it. Paste the garbled text and it instantly shows two conversions — reading your keystrokes as English turned into Thai, and as Thai turned into English — using the complete Kedmanee (เกษมณี) layout for both the normal and Shift layers. It auto-detects the likely direction, shows both results side by side, and lets you copy the right one in a click. Everything runs in your browser; nothing is uploaded.

Paste text you typed before switching keyboard language. Both conversions update instantly — no button needed.

Based on the standard Kedmanee Thai layout, both the unshifted and shifted layers. Characters that are not on the key map — such as spaces and line breaks — are left unchanged.

Your results will appear here

Paste text typed in the wrong layout to see it converted both to Thai and to English.

How to use

  1. Paste the text that came out in the wrong language into the input box.
  2. Read the two results: your keys interpreted as English → Thai, and as Thai → English.
  3. Look for the result tagged “Likely match”, which is auto-detected from your text.
  4. Click Copy on the correct conversion to grab the fixed text.
  5. Spaces, line breaks and any character not on the key map are kept as-is.

Frequently asked questions

What does the Thai keyboard fixer do?
It repairs text you typed while the keyboard was set to the wrong language. If you meant to type Thai but were in English mode you get gibberish like "l;ylfu"; paste it here and get back "สวัสดี". It also works the other way, turning mistaken Thai keystrokes back into English.
How does it know whether I meant Thai or English?
The tool always produces both conversions, then guesses the more likely one by comparing how many Thai versus English letters your input contains. That result is marked "Likely match", but you can always copy the other box if it fits better.
Which keyboard layout does it use?
It uses the standard Thai Kedmanee (เกษมณี) layout — the default on Windows and most Thai devices — mapped against US QWERTY. Every key is covered on both the normal layer and the Shift layer, including the number row and symbols.
Why does "l;ylfu" become "สวัสดี"?
On a Thai Kedmanee keyboard the letters s-w-a-s-d-i sit under the physical keys l-;-y-l-f-u. Typing สวัสดี in English mode therefore prints "l;ylfu". The tool reverses that key-by-key to recover the Thai word.
Does it handle numbers and symbols too?
Yes. The full Kedmanee mapping includes the number row, Thai digits (๑๒๓), the baht sign ฿ and punctuation on the Shift layer, so mixed text with numbers and symbols is converted correctly, not just letters.
Is my text sent to a server?
No. The conversion happens entirely in your browser with JavaScript. Your text is never uploaded, logged or stored, so you can safely fix private messages and passwords-adjacent notes.
