<a href="http://www.fontsquirrel.com/" rel="nofollow ugc">Font Squirrel</a> is your best resource for FREE, hand-picked, high-quality, commercial-use fonts. 
They provide a large part of their fonts in a web-embedding-ready way that is supported by all major browsers (@font-face CSS method).
The provided formats are : 
* TTF – Works in most browsers except IE and iPhone. 
* EOT – IE only. 
* WOFF – Compressed, emerging standard. 
* SVG – iPhone/iPad
They provide an API to list, preview and download fonts very easily : this unofficial plugin is using this official API.
When you browse fonts and dispplay one with this plugin, the font is downloaded from fontsquirrel.com. If you then choose to install the 
font, its css rule is put in the head section of you website pages so that you can use it on any page. The WordPress built-in editor 
(TinyMce) has a dropdown list that lets you choose the font you want for each part of your site.

Font Squirrel (unofficial)

Bring fonts from fontsquirrel.com into WordPress. Fonts kits are downloaded into your content directory and linked with @font-face.

Embed and use Adobe Fonts (https://fonts.adobe.com) in your WordPress website without having to edit your theme!
Adobe Fonts offers a service that allows you to select from a range of over 25,000 high-quality fonts for your WordPress website. The fonts are applied using the font-face standard, so they are standards compliant, fully licensed, and accessible.
To use this plugin, you need to sign up with Adobe Fonts, install this plugin, and then either configure some Adobe Fonts selectors or define your own CSS rules. Adobe Fonts selectors provide a quick and easy way to get fonts enabled on your site. Using your own CSS rules (as explained in Adobe Fonts’ Advanced tips) gives you more control and lets you access additional attributes such as font-weight. This plugin allows you to create your own CSS rules that use Adobe Fonts without the need to edit/upload CSS style sheets.
Detailed instructions are available on the plugin’s settings page.
This plugin by default uses Adobe Fonts’ CSS embed code (https://blog.typekit.com/2017/11/16/new-on-typekit-load-web-fonts-with-css/). However, if you prefer, you can use the asynchronous JavaScript embed.
Compatible with WordPress Multisite.
