What is a .woff2 file?

WOFF2 is the successor to WOFF, using Brotli compression to shrink web fonts substantially further than the original format. It wraps TrueType or OpenType outlines for efficient browser delivery and is the preferred modern web font format. It offers the smallest sizes with broad current-browser support.

How to use this file

Use an example WOFF2 to test Brotli-based font decoding, web-font delivery performance, and @font-face support with fallbacks to WOFF.

How to use this file for testing

“WOFF2: Colour Font, COLR v1 Gradients” is a deterministic Testaroo fixture for Conversion testing, Web assets. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.

Documented properties for this file: seed 20260807. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such, expect parsers to fail loudly rather than silently accept them.

Font fixtures carry a small documented glyph set across the common wrappers. Test font loaders, subsetting, and @font-face; the specimen preview renders the glyphs the face actually maps.

Code examples

@font-face {
  font-family: "Sample";
  src: url("NovusColorGradients.woff2");
}
body { font-family: "Sample", sans-serif; }
