Features & Guide

Features

Search, compare, and organize fonts. This page collects what stac can do in one place. Start with the overview, then open each feature with the “+” button for a more detailed guide.

Free

Google Fonts Preview

Preview Google Fonts alongside your local library

Preview Google Fonts directly inside the app. Because you can compare them with local fonts and dragged-in files using the same text and the same settings, the flow from searching to comparing stays smooth.

Free

Language Filter

Narrow candidates by language support

Filter fonts by supported writing systems such as Japanese, Korean, or Chinese. Instead of getting buried in Latin-only options, you can focus on fonts that actually work for the language you need.

Free Pro

Compare Mode

Review your shortlist with more confidence

Select only the fonts you want to review and examine them in a dedicated comparison workspace. Switch between list view, grid view, and detail view to judge differences step by step.

Detail View lets you inspect one shortlisted font at a larger scale, and in Pro you can also adjust the background image, mask, and text color.

Browse & Preview
