## What Is Fontmatrix?

Fontmatrix is a dedicated font manager built for Linux and available across platforms. It works seamlessly on both KDE and GNOME desktops, filling a gap that was previously only partially addressed by tools like KFontInstaller.

## Font Discovery & Indexing

Point Fontmatrix at any directory and it will recursively scan for TrueType (.ttf), PostScript (.ps), and OpenType (.otf) fonts. The indexer is fast, automatically skipping corrupted or broken font files, and presents your entire collection sorted and ready to browse.

## Tagging & Organization

Organize your font library with a flexible tagging system. Create tags, nest sub-tags, and re-sort your collection on the fly. Tags form the basis of user profiles — group fonts by project, client, or workflow and switch between them instantly.

## Activation & Deactivation

Activate or deactivate fonts on demand using the tag-based profile system. Family checkboxes automatically group all variations of a typeface — regular, italic, bold, and other weights — so you can toggle an entire family with a single click, or select individual faces one by one.

## Preview & Inspection

Each selected font offers multiple views:

• • Name & family info — quick identification at a glance
• • Detailed metadata — full font information and technical details
• • Word preview — customizable single-word sample
• • Sentence preview — full pangrams or custom character sets, with the ability to save multiple presets in preferences
• • Glyph view — browse characters by Unicode subset (Basic Latin, Punctuation, Mathematical Operators, or all glyphs)

## PDF Font Book

Generate a PDF font book from your collection — a printable reference of your tagged and organized fonts, useful for client presentations or personal archives.

## FontForge Integration

Spotted a missing glyph or need to tweak a character? If FontForge is installed on your system, you can launch it directly from within Fontmatrix to edit any font on the spot.
