PDF Viewer Secure

View PDFs offline in VS Code with bundled PDF.js and restrictive defaults. Requires VS Code 1.111 or later.

Install from Marketplace, then open a .pdf file.

Defaults and settings

• External links, file imports, downloads (including attachments), printing, forms, and annotation editing are off by default.
• Enable optional features with pdf-preview.features.* in VS Code settings.
• Adjust zoom, cursor, sidebar, and page layout with pdf-preview.default.*.
• PDF JavaScript stays disabled, even when forms are enabled.

Copilot Agent tools

Enable pdf-preview.agent.enabled in User Settings, then select the tools in Copilot Agent chat:

• #pdfPreviewOpen: open a workspace PDF and report its loading status and page count.
• #pdfPreviewStatus: check a PDF preview by its absolute file path.

Tools require a trusted local workspace and reject paths outside it, including symlink escapes. They return the path, status, and page count to the chat; they do not extract PDF text or provide OCR. These are VS Code tools, not a standalone MCP server or Agent Plugin.
