WebFont: Subset & Convert

WebFont is a macOS utility for font conversion, subsetting, and web delivery packaging. All processing runs locally on your Mac. What you can do Font Conversion - Convert between TTF, OTF, WOFF, and WOFF2. - Use Single Font Conversion or Batch Font Conversion queue workflows. - WOFF2 encode/decode is backed by Google's WOFF2 library. Subset Generation - Build subsets from Current Selection or Text Input mode. - Paste text or import .txt to extract characters for subsetting. - Apply Unicode preset groups (General / Japanese / Korean) and block-based filtering. - Export subset outputs as WOFF2, WOFF, and/or TTF. - Control OpenType layout handling: - Preserve all layout features - Keep essential positioning only - Remove all layout tables - Optional OpenType feature-tag filtering (keep selected / remove selected tags). Web Package Export - Generate a web package in one step: - fonts/ (WOFF2 + WOFF) - CSS with @font-face and unicode-range - demo.html preview page - Demo includes live text/size preview and a Character -> Unicode -> HTML Entity reference table. Glyph Asset Export - Export selected glyphs as SVG, PNG, or PDF. Quality & Risk Checks - Validation runs before output is written. - Checks include decoder/parser validity, required table presence, missing cmap mappings for selected code points, duplicate Unicode mapping conflicts, and compatibility warnings. Multi-Window Workflow - Open multiple windows (File -> New Window) to compare A/B settings side by side. Privacy - No cloud upload. - No external processing. - Your font files stay on your device. Notes - Subset generation currently supports TrueType-outline fonts.
