Font Studio: Font Engineer

Font Studio is a professional font editor and engineering toolkit for Android. Inspect, edit, compose, convert, optimize and repair TrueType and OpenType fonts directly on your device.

BUILT FOR REAL FONT WORK

Font Studio is designed for type designers, developers, students, font enthusiasts and anyone who needs to work with real font files without opening a desktop application.

Use it to edit a TTF or OTF font, inspect OpenType data, adjust kerning, remove unused glyphs, convert font formats, compose typefaces, optimize files or prepare fonts for your next project.

Font processing happens on-device. Your font files are not uploaded for processing.

Font Studio supports standard TrueType and OpenType workflows and is designed to give you professional font tools wherever you work.
