![]() Then, when the browser is ready to start painting the text, it already has the font available and can start displaying the text right away. With font preloading, you can force a visitor’s browser to load important fonts early on so that the browser can start painting text as soon as it’s ready, rather than potentially waiting to load the font.įont preloading doesn’t tell the browser what the font will be used for – it just says “hey, download this font right away so that it’s ready to go”. The reason you want to avoid this situation is that it slows down the perceived page load times for your visitors, which leads to degraded user experience. That is, it needs to download the font before it can paint the text. In summary, without font preloading, you might run into a situation where a browser is ready to load your site’s text, but it can’t because the font isn’t available yet. Once the font file loads, the text will switch to the new font style, which can cause a jarring experience for your visitors as the text appears to “jump” and “transform”.

However, this lazy loading approach can lead to situations where the browser is ready to start displaying text but, because it hasn’t downloaded the font yet, the browser needs to delay painting the text until it has downloaded the font. Basically, the browser is lazy loading the font files so that it only starts loading a specific font once the browser knows that the font is needed ( it knows that the font is needed because it already needs to use that font to “paint” text on the screen). I know that’s a little technical, so let me try and break it down into more human-friendly terms.Įssentially, with the default behavior, a browser will wait to load the font file until after it starts “painting” visible content to the user’s screen.
