FAQ
What is Hanyu Pinyin?
Hanyu Pinyin is the official Romanization system for Standard Mandarin Chinese in mainland China, Singapore, and international language education. It transcribes Chinese characters into the Latin alphabet with tone accents.
How do the 4 Mandarin tones and neutral tone work?
Mandarin has four primary tones: 1st tone (high flat, e.g. mā / ma1), 2nd tone (rising, e.g. má / ma2), 3rd tone (dipping/falling-rising, e.g. mǎ / ma3), 4th tone (falling, e.g. mà / ma4), and neutral tone (unmarked / ma).
Can I choose between tone marks and tone numbers?
Yes. You can switch between diacritic tone marks (nǐ hǎo), numeric tone notation (ni3 hao3), or tone-free letters (ni hao).
Does this converter run offline and protect my text?
Yes. All character lookups and phonetic conversions run entirely inside your browser using client-side JavaScript without transmitting your text over the network.
