Simple Custom Font Replacer helps merchants use their own font files across storefront elements such as headings, body text, links, and custom CSS selectors. Fonts are uploaded to Shopify Files, rules are managed in the app, and the storefront applies the selected styles through a theme app embed. Merchants can choose the active theme after a theme update and keep font rules organized in one place.

• Upload .woff2, .woff, .ttf, or .otf font files
• Apply fonts to headings, body text, links, or custom CSS selectors
• Choose which theme should use the app after theme updates
