I’ve used this website so much in the last few months when writing ChineseHacks posts that it deserves a mention. Pinyin Generator is a simple that does one thing, convert Chinese characters into their Pinyin pronunciation with tone marks.
It’s not always perfect and if the character has multiple pronunciations then sometimes the one you don’t want is displayed – I recently wanted xíng from 行, but the website gave háng, another common pronunciation. The solution was to use another character that I knew had the pronunciation I wanted, such as 型. A mentioned above, it’s nothing special, just a simple, useful tool that might save you when you quickly need to generate some Pinyin.
I should also say that under normal circumstances I use Pinyin Dictionary by Ideographer (Featured in Useful Mac Apps for Learning Chinese), but it has a bug when used with dual monitors that leaves it off screen when the second monitor isn’t connected, no good when you need to write a blog post about Chinese.
if you know of a better Pinyin generating tool or website then please post below in the comments.
