OpenType Font vs Web Open Font Format 2

Why convert OTF to WOFF2?

• Web delivery usually benefits from a container designed for browser loading.
• A separate webfont keeps the desktop source untouched.
• WOFF2 is better suited to the delivery environment, especially when the target is a website.
• Separate web and desktop copies make it easier to respect licensing and rendering constraints.

Will quality change?

The font outlines should remain the same, but the container and compression change. Test the result in the target browser or application. Keep the source if you may need to adjust the conversion later.
