Fonts Ninja review
Free browser-focused font identification with DNA analysis, similarity suggestions and catalog search.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Fonts Ninja is a free font-identification service for designers, developers and other people inspecting typography on webpages. Its browser extensions identify rendered fonts and show the font name, size, line height, letter spacing and color. The service also offers iPhone, iPad and Mac apps, with availability through Chrome, Firefox, Edge and Safari extensions. Solo users and small teams get a focused way to investigate type choices while browsing.
The standout workflow goes beyond naming a typeface. Font DNA analyzes the rendered font file, while AI-powered suggestions surface similar typefaces. Users can bookmark discoveries into personalized font boards, then search the catalog by designer, foundry, style, language, character shapes, license type and price. The catalog also provides purchase information, so Fonts Ninja can connect identification with subsequent typeface research. The software itself is free; any font licenses shown in the catalog are sold by third-party foundries.
Fonts Ninja is strongest when the source is live webpage text and the task is identifying, comparing or organizing typefaces. It is less suitable for image-led identification because it does not provide image matching, and its workflow is centered on browser inspection rather than broad asset analysis. The Apple apps extend access beyond extensions, but the listed native mobile and desktop options are Apple-focused. Choose Fonts Ninja for webpage typography research and lightweight font discovery; choose another tool when screenshot or image matching is essential.
