About POJ Composer
A free tool for writing Pe̍h-ōe-jī — the Latin-script romanisation of Southern Min — with correct tone marks, without fighting your keyboard.
What it is
POJ Composer turns a plain, numbered spelling into properly tone-marked Pe̍h-ōe-jī. You type something like Goa2 si7 Tai5-oan5 lang5 and get Góa sī Tâi-oân lâng back instantly. It handles the awkward parts of POJ for you: placing each tone mark on the right vowel, and rendering the dotted o͘ and e͘ that most keyboards and fonts struggle with.
Why it exists
Hokkien is a living language spoken by tens of millions of people across Taiwan, Fujian, and Southeast Asia, but writing it in POJ has always been fiddly. Tone diacritics are hard to type, the special vowels are hard to produce, and the rules for where a tone mark goes are not obvious to beginners. POJ Composer exists to remove that friction — so learners, teachers, writers, and anyone keeping Hokkien alive can write it quickly and correctly.
The converter’s tone-placement logic is adapted from a Penang Hokkien (Pe̍h-ōa-jī) project, and the tool deliberately supports several dialect and spelling variants, including the Penang spellings and the Quanzhou er/ir vowels.
Who made it
POJ Composer is built and maintained by Lee Chun Hoe (Lí Chùn-hô), an independent developer with an interest in Hokkien language tooling. It’s a personal, non-commercial project, kept free and supported by unobtrusive advertising.
Privacy & how it’s funded
Conversion happens entirely in your browser; nothing you type is sent anywhere. The site is kept free with ads served through Google AdSense. For specifics, read the privacy policy and terms and conditions.
