Converting Pinyin Tone Numbers to Diacritical Tone Marks

I’m asked from time to time if I know of any tools to convert pinyin with tone number indicators–such as ma1 ma2 ma3 ma4–to pinyin with diacritical marks–as in ma má ma mà.

One of The Chinese Outpost’s esteemed long-time readers asked today, it reminded me to record a few links to online tools that will perform this type of conversion for you.

The ones I use (in no particular order):

• MandarinTools.com (Gives you lots of romanization options)
• Pinyin.info (Gives you lots of output format options)
• Fozza.com (Works clean and crisp, with a hint of minty freshness)

So, bada-bing, there they are.
