Pinyin
tone converter

Enter numbered pinyin, then copy the result into your notes, word lists or teaching materials. Your text stays on this page.

From numbers to marks

Ni3 hao3, Zhong1guo2!

Nǐ hǎo, Zhōngguó!

End each syllable with 1–4. Use 0 or 5 for a neutral tone. Up to 10,000 characters.

The converter preserves spacing, punctuation and capitalisation; it does not split joined words.

Conversion happens in your browser. This tool does not save or send your text. If you allow website analytics, we count actions such as conversion and copying, without the text or its length.

Accepted input

  • One tone number per syllable. Enter ni3 hao3 for nǐ hǎo. Joined syllables work too: Zhong1guo2 becomes Zhōngguó.
  • Three ways to type ü. lü4, lv4 and lu:4 all become lǜ. Use nüe4, nve4 or nu:e4 for nüè.
  • A neutral tone stays unmarked. ma5 and ma0 both become ma.
  • Keep standard spelling after j, q, x and y. Use ju4, qu4, xu1 and yu3. Pinyin leaves out the two dots of ü in these spellings.

This tool accepts common Mandarin syllables with a vowel. Syllabic consonants such as m and ng, the separate vowel ê, and added erhua suffixes are not supported. It checks supported spellings, but does not check a word’s meaning, choose its tone, apply tone changes in speech or translate Chinese.

Tone placement

RuleInputOutput
Mark a when present.hao3hǎo
Otherwise, mark e.mei2méi
In ou, mark o.dou1dōu
In iu and ui, mark the last vowel.liu2 shui3liú shuǐ
Otherwise, mark the remaining vowel.lv4lǜ

If the input contains an unsupported group, the converter keeps your text and selects the first group to check. Add a number to each syllable, check the spelling, then convert again.

Tone placement and standard ü spelling follow the 汉语拼音方案 and GB/T 16159–2012. This tool also accepts 5 as a practical neutral-tone input.
