What changes when English becomes Thai
Polite particles depend on the speaker
Polite Thai sentences usually end with a particle that English does not have: male speakers use ครับ (khrap), female speakers use ค่ะ (kha). Since an English sentence rarely shows who is talking, the translation has to pick one. Check it before you send a message, and use the Tone menu to choose between Formal (business email) and Casual.
A script without spaces between words
Thai is written left to right in its own alphabet, with no capital letters. Words run together, and a space usually marks the end of a phrase or sentence rather than the end of a word. English punctuation habits, like commas in long lists, often do not carry over.
Tense and counting work differently
Thai verbs do not change form for tense. Time comes from context or small words such as แล้ว (laeo) for something already done and จะ (cha) for something still to come. Counting needs a classifier: หนังสือสามเล่ม (nangsue sam lem) means “three books”, literally “book, three, classifier for books”.

Common tasks — English to Thai
How do I get my English text in Thai (เอาภาษาไทย) on this page?
Paste or type your English text in the left box, or click Dictate and speak. The Thai translation appears on the right, and you can change the Tone or click Show pronunciation if you need to.
Why does the Thai translation sometimes end in ครับ or ค่ะ?
These are polite particles. ครับ is used by men and ค่ะ by women. English does not show the speaker’s gender, so check that the particle fits you, or choose Casual when a lighter tone suits the message.
Can I translate to Thai words and short phrases, not only full sentences?
Yes. Single words and short phrases work too, but many English words have several Thai equivalents. Click Show alternatives to see 2–3 other phrasings that differ in register.
How much text can I translate at once, and can I upload a file?
Each run takes up to 5,000 characters, so split longer texts into parts. You can open a DOCX, ODT, RTF or TXT file, and its text is placed in the editor. Formatting is not kept, and PDFs and images are not supported.
Is it safe to paste private messages or work emails?
Your text is sent to an AI model, translated, returned and then discarded. It is not stored and not used for training.
Can I see how to pronounce the Thai result?
Click Show pronunciation to get an approximate RTGS-style romanization under the result. RTGS does not mark Thai tones, so use Read aloud to hear the translation spoken.
Is this Thai translator free for quick eng to Thai messages?
Yes. It runs in your browser for free, with no signup, no account and nothing to install.
Can I translate Thai back into English?
Yes. Click Swap languages to reverse the direction. Your text stays in the box, so you can check a reply or run a Thai message back into English.
