iFontCloud is a cloud font service offering licensed font rentals and web fonts, with products from Arphic and Morisawa. Its catalog can be filtered by type, weight, language, application, style, and designer, and supports TTF/TTC and OTF formats. Rental licenses run annually, and fonts included in a plan may be used during its license period. The Windows and Mac desktop app lists Windows 10 with .NET Framework 4.6 or macOS 10.13 and later as requirements. Supported applications include Adobe Illustrator, Photoshop, After Effects, InDesign, and Premiere Pro, along with Microsoft Office and Apple Keynote, Pages, and Numbers. Registered members can access four free fonts to check software compatibility. Members with an active font or package order can install included fonts on one iPad or iPhone through the app at no extra charge. One account can be used across multiple computers, but only one computer can be logged in at a time. The service also offers personal and commercial web font plans selected according to page views. Work completed during a license period may continue to be sold after the font plan is not renewed.
