SwapMyFont — Font Substitution Tool

Challenge

Designers often receive fonts they cannot license for production. Generic "Helvetica alternatives" lists guess at similarity — they do not prove a substitute works on the client's actual brand name, headline or UI string. SwapMyFont needed to rank substitutes with measurable proof designers could show stakeholders.

Solution

• Upload or pick a reference font — licensed files processed locally in the browser, never sent to a server
• Ranked Google Font matches scored on contour, width, x-height and ink metrics
• Per-glyph visual comparison on the user's real sample text, not just pangrams
• Coverage warnings for missing characters, numerals and punctuation
• Plain-language license badges with 14 popular preset searches (Helvetica, Futura, Gotham and more)
• Marketing site with methodology, FAQ and preset library

Result

SwapMyFont gives designers and developers ranked substitutes with glyph-level proof they can share with clients — turning "close enough" into a documented decision before ship.
