What is Looq?
Looq is a Quick Look extension that lets you preview Markdown, source code in 200+ languages, SQLite databases, TSV files, diffs, archives, and folders right from Finder. See the Looq page for a full list of supported formats.
How is Looq different from the built-in Quick Look?
The built-in Quick Look shows plain text for most developer files. Looq adds syntax highlighting, Markdown rendering, SQLite browsing, archive inspection, and more, all inside the same spacebar preview you already use.
Is Looq a subscription?
No. Looq is a one-time purchase. See the Looq page for current pricing and purchase options.
Which macOS versions are supported?
Looq requires macOS 15 (Sequoia) or later.
Does Looq access my files or send data over the network?
Looq reads only the file you are previewing and processes it locally. Network activity is limited to fetching remote images referenced in Markdown files, license activation and verification, update checks, and anonymous telemetry (which you can disable in Looq’s preferences). See the privacy policy for details.
How do I request a new file format or report an issue?
Use Help > Send Feedback… in the menu bar. This automatically includes your macOS version and Looq version, which helps us diagnose issues faster. You can also email hello@parcse.com directly. If requesting a new format, include a sample file if possible.
Quick Look previews are not showing up, or only work for some file types.
Open Help > Looq Diagnostics… in the menu bar. It checks extension registration, conflicting apps, legacy plugins, and file type mappings automatically, and includes repair options like clearing the Quick Look cache. If the issue persists, you can send a diagnostic report to support directly from the same window.
