USE CASES
Use Cases for OTF to WOFF
Common reasons people convert OTF files to WOFF.
Add a custom typeface to a design system
Create a web-font copy for product UI, marketing sites, dashboards, or documentation portals.
Standardize web-font assets across a project
Move supported source fonts to WOFF when the front-end pipeline expects one consistent web format.

Prepare a font for an offline web app
A local WOFF copy can be packaged with a browser-based app when remote font hosting is not appropriate.
Create a self-hosted web-font package
Use WOFF when a project serves font files from its own domain rather than a third-party font service.
Prepare a font for a website
Convert OTF to WOFF for use in a browser-based @font-face workflow when the font license permits web embedding.
Prepare fonts for a static site
Convert the font before bundling it with HTML and CSS assets for a documentation site or landing page.
Reduce font transfer size for web delivery
WOFF is designed for browser use and can be more practical than a desktop-oriented OTF file in a web project.

Prepare WOFF files for testing on a private staging site before production deployment, subject to licensing.
Support a CSS font stack with a web format
Use WOFF as the web-delivery asset while keeping the original OTF as your licensed source file.
