About OTF to WOFF2 conversion
OTF is the OpenType font format launched by Microsoft and Adobe in 1996, which supports CFF outlines and advanced typography features. WOFF2 is an open web font format released by W3C in 2018. It uses Brotli compression, is specifically designed for the web @font-face scenario, and conversion meets the requirements of web font loading.
The conversion generates a WOFF2 container compressed with Brotli, retains the CFF outlines and advanced typography features of the original OTF. The file size is significantly reduced compared to the original OTF, font hinting information is completely retained, and the original font license terms can be fully inherited.
The converted WOFF2 can be referenced via @font-face in modern desktop and mobile browsers, compatible with Chrome 40+, Firefox 38+, Edge 14+ and Safari 10+, and is suitable for use in website front-end development workflows.
