Turn font files into an SD-card font family. Choose your sizes and character coverage; this page does the conversion on your computer.

Font family

TTF / OTF → CPFont v4

Family name on the reader

Letters A–Z, numbers, hyphens and underscores. Use a new name to keep an existing family.

Regular font

Use a static font face. Thai positioning requires all supported Thai characters in each primary style.

Regular fallback fonts optional

Used in the displayed order when the primary font lacks a character.

Add bold, italic or bold italic

Styles are optional. Each style has its own fallback list; regular fallbacks are not applied to other styles.

Include font licenses

License files to include in the ZIP

Conversion does not grant redistribution rights. Include the font’s license if you share the generated files.

Sizes & coverage

Point sizes · 150 DPI

8, 10 and 12 pt also supply size-matched UI fallback. Only the selected sizes are included.

Additional Unicode coverage

Base coverage is always included. Check the extra scripts and symbols your readers need.

Base: Basic Latin (U+0020–007E), punctuation (U+2000–206F), and replacement character U+FFFD. Presets overlap; duplicate ranges are merged.

Upload fallback fonts above to fill missing coverage. Selection cannot create glyphs absent from your fonts; unavailable codepoints are omitted and counted in the report. Chinese variants share Han ranges—the source font determines regional glyph forms. Wider coverage makes larger files.

Additional Unicode ranges optional

Comma-separated hexadecimal ranges, optionally prefixed with U+.

Bake Thai positioning Create a matching CPSHAPE v1 companion for each size. This is Thai-specific, not a shaping engine for every script.

Rasterization options

Force FreeType auto-hinting Leave off to use the source font’s default hinting.

Conversion runs on your computer. Large character sets can take longer and use more browser memory.
