Pick a style for the destination
Tone marks suit human reading: hàn yǔ. Numeric tones are convenient for plain-text systems: han4 yu3. Plain spelling removes tone information; initials keep only the first letter of each syllable. Numeric and plain modes use v where ü is needed. Initials are a shortcut, not a pronunciation guide or a guaranteed unique identifier.
Give the converter useful context
Paste a complete sentence rather than an isolated ambiguous character when possible. The included phrase dictionary can distinguish many common readings, but personal names, rare characters and unfamiliar place names should be checked. This tool provides Mandarin romanization, not Cantonese or an audio recording.
Keep paragraph structure
Input line breaks are retained so the result can sit beside the Chinese original. Consecutive non-Chinese text is preserved as a group, with spacing added between converted syllables. This is plain text, not a ruby-annotated document or an exact whitespace-preserving text transform.
Save and review the learning aid
Import UTF-8 TXT or paste up to 100,000 characters / 400 KB, convert, inspect the complete result and download TXT. Compare difficult words with a trusted dictionary or teacher. Keep the original Chinese file because clearing or leaving the page discards the workspace.
