The tool lists a curated set of common system fonts including popular Latin fonts (Arial, Verdana, Helvetica, Times New Roman, Georgia, Courier New) and common CJK fonts (Microsoft YaHei, SimHei, SimSun, KaiTi, FangSong, PingFang SC). All fonts are rendered using your local system — no font files are downloaded.
Fonts must be installed on your operating system to be rendered. If a font such as PingFang SC or Microsoft YaHei is not installed on your device, the browser will fall back to a generic sans-serif font. This is a normal browser behavior and does not indicate a bug in the tool.
Click "Copy CSS Style" to copy the generated font-family declaration to your clipboard. Paste it into the relevant CSS selector in your stylesheet. The output includes a generic fallback (sans-serif) so text remains readable even if the primary font is not available on the user's device.
