What is a WOFF2 file?
WOFF2 (Web Open Font Format 2.0) is the successor to WOFF 1.0, standardized by the W3C in 2018 to further optimize web typography performance. The primary technical advancement in WOFF2 is the implementation of the Brotli compression algorithm, which offers approximately 30-50% better compression rates than the zlib method used in WOFF 1.0. This format reconstructs the original TrueType or OpenType tables using a transformed and entropy-coded storage format, significantly reducing network payload for high-speed page loads.
How to open a WOFF2 file
As a web-specific resource, WOFF2 files are natively rendered by modern web browsers including Google Chrome, Mozilla Firefox, and Microsoft Edge. They are not executable or viewable by standard desktop image or text editors. To utilize the glyphs in a desktop environment or specifically view the file architecture, the file must be decompressed and converted to OTF or TTF using command-line tools like Google's woff2 utilities or specialized font conversion software.

What is an OTF file?
The OpenType Font (OTF) format is a cross-platform scalable font standard developed jointly by Adobe and Microsoft in 1996 to supersede TrueType and PostScript Type 1 formats. OTF files encapsulate outline data using either Compact Font Format (CFF) based on cubic Bézier curves (PostScript) or TrueType outlines based on quadratic Bézier curves. The format adheres to ISO/IEC 14496-22 (Open Font Format) standards and supports advanced typographic features such as ligatures, glyph substitution, and alternate characters via feature tables (GSUB, GPOS).
How to open an OTF file
OTF files enjoy native support across all major operating systems, including Windows, macOS, Linux, Android, and iOS. Users can install the font by double-clicking the file to launch the OS-native Font Viewer (Windows) or Font Book (macOS) and selecting the install option. For editing glyph paths or kerning metrics, vector graphic editors like Adobe Illustrator or dedicated typography software such as Glyphs and FontLab are required.
