Unfold

Preview folders, archives, source code with syntax highlighting, Markdown, Mermaid diagrams, ebooks, and many more file types directly in macOS Quick Look.

• Look inside folders and archives without opening them.
• Inspect source code files, configs, and project assets with syntax & text highlighting when you just need a quick look.
• Preview notes, READMEs, and drafts as formatted Markdown instead of plain text.
• View Mermaid charts as rendered diagrams instead of raw syntax.
• Take a peek at comics in .cbz and .cbr format.

Over 100 total supported file extensions.

Some file types aren’t supported because there is already built-in Quick Look previews for them, including .txt, .rtf, .html, .webarchive, .ts, .pdf, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .odt, .ods, .odp, .pages, .numbers, and .key. Unfold focuses on formats that aren’t natively supported.
