Document Viewer FAQ

Can I view Word documents without Office?

Yes! Our DOCX viewer extracts and renders text, formatting, tables, and images from Word documents directly in your browser. No Microsoft Office, Google Docs, or LibreOffice needed.

What Markdown features are supported?

Our Markdown viewer supports GitHub Flavored Markdown (GFM) including headings, bold/italic, links, images, code blocks with syntax highlighting, tables, task lists, blockquotes, and horizontal rules.

Our PDF viewer focuses on metadata extraction — title, author, creation/modification dates, page count, producer software, and more. For full PDF rendering, we recommend using your browser's built-in PDF viewer.

Is SVG rendering secure?

Yes. All SVG content is sanitized using DOMPurify before rendering, which strips any potentially malicious scripts while preserving the visual content.

DOCX files up to 50MB, Markdown up to 20MB, PDFs up to 30MB, and SVG files up to 30MB. These limits ensure smooth in-browser performance.
