File Viewer MackRais

File Viewer MackRais brings documents, ebooks, diagrams and structured data together in one desktop viewer.

SUPPORTED CONTENT

• Documents: PDF, DjVu, Word documents and RTF.
• Ebooks: EPUB and FB2.
• Office files: Excel spreadsheets, PowerPoint presentations and OpenDocument files.
• Markdown and Mermaid: read Markdown documents and preview Mermaid diagrams from .mmd files.
• Structured data: inspect JSON with optional pretty formatting, XML and XHTML.
• Images and other documents: view common image formats, HTML and XPS.

DIAGRAM VIEWING

Preview Mermaid diagrams alongside their source code or display them separately. Zoom in to explore detailed diagrams and export them as images or SVG.

FLEXIBLE READING

Choose a single-page view, a custom page grid or a main page with scrollable thumbnails. Navigate through the document's table of contents when available, jump to a page and reopen recent files.

USEFUL TOOLS

• Copy text from documents that contain a text layer.
• Export individual pages as PNG, JPEG or WebP.
• Print documents with page and printer settings.
• Open files using drag and drop or the file picker.
• Choose a Ukrainian or English interface.

FORMAT NOTES

Available features depend on the file format and document contents. Scanned PDF and DjVu pages need an existing OCR text layer for text selection and copying. Office documents are converted for viewing, so complex formatting may differ from the original application. Office macros and add-ins are not executed.
