The attached font is the template
Font Studio reads one static TTF variant in a Web Worker. Its glyph order, IDs, Unicode map, metrics, and shaping tables form the project structure.
Only glyphs you deliberately redesign need separate project records. Every untouched glyph continues to come from the attached template.
Work remains on the device
The template and changed glyph data are saved in IndexedDB under the current browser profile. Lipi servers never receive or process the font, glyph designs, or project backup.
Local storage is not encrypted and can be removed by browser cleanup, private browsing rules, or device loss, so portable .lipiproject backups remain important.
Review, design, and synchronize
After reviewing the source identity, shaping tables, and license, select a glyph and open the focused editor. Saved modal edits immediately synchronize with the browser project while untouched glyphs continue to use the source outlines.
Heavy tools load only when needed
Font parsing starts after a font is selected. Freehand drawing is provided by a small focused library, and WOFF2 compression loads only when that export format is requested.
