TTF to WOFF2

The tool accepts a TTF font file and converts it to the WOFF2 format, optimized for web delivery and performance budgets. It validates the input font structure, preserves essential metadata and license information, and ensures the resulting font remains operable across major browsers with consistent kerning and hinting behavior. The conversion is standards-compliant, using the official WebFont profile, and does not alter the glyph outlines beyond the intended subset selections. It also reports basic validation results to help teams decide readiness for production use.

Core logic includes optional glyph subsetting: when a subset is supplied, the converter builds a glyph set from Unicode ranges or explicit codepoints, reducing file size while maintaining the visible characters. It uses the standard WOFF2 encoding (Brotli-based) and updates 'name', 'OS/2', 'cmap', and 'head' tables to reflect the new font properties and licensing constraints. If no subset is requested, the full font is encoded with default settings, providing maximum character coverage.

Output is a downloadable WOFF2 file, with an optional summary describing original versus converted size, subset details, and font naming adjustments. This tool supports web developers, CMS teams, performance engineers, and font distributors seeking reliable, scalable font delivery and easier font management across multiple environments.

Operationally it integrates with build pipelines and content workflows, enabling automated font preparation for release cycles. It enforces size budgets, supports language- or region-specific subsets, and helps ensure licensing compliance while enabling consistent typography across sites and apps.
