Font Converter

About This Tool

This tool transcodes font files between common formats (TTF, OTF, WOFF, WOFF2, SVG fonts) to support web and native apps. It analyzes input font metadata, checks licensing constraints, and outputs a format-appropriate file ready for deployment. Target audience includes web developers, product designers, game studios, and font engineers who need predictable asset formats in pipelines.

Core workflow: provide inputs including the source font file, source_format, target_format, and optional options like subset characters or included hinting. The converter applies domain-specific rules: preserves kerning and glyph metrics where supported, applies subset selection by Unicode ranges, and optionally compresses for WOFF2. Outputs include the converted font file and optional CSS/font-face snippet, along with a JSON metrics report.

Value and differentiators: automatic license-preserving metadata, batch processing, and advanced options such as glyph subset generation and hinting preservation. It integrates with build systems and asset pipelines, reducing manual steps and avoiding broken fonts in production. Error handling covers unsupported formats, invalid or corrupted fonts, missing inputs, or licensing restrictions.

Standards and localization: aligns with web font deployment guidelines (CSS font-face) and supports Latin and extended Latin glyphs with potential future expansion for broader scripts. Size metrics use bytes, with clear reporting on post-conversion results. Assumptions: input fonts are legally licensed for conversion; it does not enforce licensing terms or guarantee perfect kerning across all formats; licensing checks are advisory.
