What Analyser reads
Preview fonts and read their metadata: TrueType (TTF), OpenType (OTF), web fonts (WOFF, WOFF2), and collections (TTC), with variable-axis animation.
Depth of analysis
.WOFF is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
Open a .WOFF file
Drag a .WOFF file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
