字体换成苹方 is a free Chrome add-on developed by Jiang Lei. It falls under the Browsers category and specifically the Add-ons & Tools subcategory. This add-on allows users to change the font of all text displayed in their browser to PingFang, provided that the PingFang font is installed on their operating system.

For an optimal experience, it is recommended to use the CentBrowser browser and disable the DirectWrite feature before installing this add-on. Additionally, users can enhance the effect by using the PingFang font in conjunction with Mactype on Windows.

The code for this add-on is primarily based on a Japanese extension called "強制メイリオちゃん MSゴシック置き換え版," and the original author is acknowledged for their work.
