Looq

Render Markdown with GitHub Alerts, KaTeX math, Mermaid diagrams (including XY Chart), tables, and footnotes. Org-mode (.org) files get a dedicated rich preview too. Live Rendering refreshes the preview as you edit, scroll position resumes where you left off (choose Off, Session, or Persistent), and the table of contents tracks your view.

Syntax highlighting across 200+ programming languages, with sticky function and class headers so you never lose context in long files. Diff and patch files render side-by-side with color-coded line markers and add/delete statistics. Customizable themes for light and dark.

SQLite and TSV files open with smart pagination (500 rows per page), column sorting, and column type tooltips, so huge files stay responsive. SQL is auto-formatted for readability.

Browse the contents of ZIP and TAR archives, plus regular folders, without extracting a thing. Enhanced folder icons and SVG thumbnails make scanning easier.

Rich previews for app bundles, IPAs, installer packages, provisioning and configuration profiles, torrents, and disk images. See what's inside before you decide to install.

Detect and repair conflicting Quick Look extensions with one-click fixes. When something breaks Quick Look on macOS, Looq tells you which app is responsible.
