Before You Ship a Font, Check What Is Actually Inside It

Need to Inspect a Font File's Metadata?

You downloaded a font and you are not sure what is inside it. Is it a variable font? How many glyphs does it contain? What OpenType features are supported? You could install it and guess, or you could inspect the file directly before committing to it.

OnliTools Font Inspector

OnliTools Font Inspector reads font metadata, glyph counts, metrics, and Unicode coverage directly in your browser. Upload a TTF, OTF, WOFF, or WOFF2 file and get a detailed breakdown without installing anything.
