This tool is used to view and inspect existing font files. It does not identify fonts from images.
Capabilities explained
Preview formats and parsing capabilities
Supports importing TTF, OTF, WOFF, and WOFF2 formats; Some fonts may only be previewed via browsers and cannot fully parse metadata or character mappings.
Glyph inspection and usage rights
Character mapping helps detect missing glyphs, while metadata provides information about the designer and copyright. Permission for commercial use must be confirmed by checking the font license; it cannot be determined based solely on preview results.

Frequently Asked Questions
Which font formats are supported?
Supports common TrueType (.ttf), OpenType (.otf), WOFF, and WOFF2 font files.
Why do some glyphs display as blank squares?
Some glyphs do not have direct character encoding assignments, or are themselves ligatures, alternate glyphs, or control characters, and may therefore appear as blank or placeholders in the character mapping.
Why can a font render without complete details?
There is a discrepancy between browser rendering and the support of the current font parser. The file might contain abnormal or missing fields. It is recommended to first verify its format and source, keep the original file, and then try other inspection tools.
