Features & Capabilities

Open in Sumatra PDF and DJVU Reader is a Chrome extension designed to seamlessly integrate PDF and DJVU file handling using the open-source Sumatra PDF software. It adds a convenient right-click context menu option to open PDF links directly in Sumatra PDF or allows sending files via a browser action button. Since Sumatra PDF doesn't support HTTP/HTTPS directly, the extension downloads files locally first, ensuring smooth access through the native app.

The extension relies on a native helper module executed through NodeJS to communicate with Sumatra PDF, requiring an initial setup guided during first use. There is no server-side interaction besides the file download process. This safe and efficient tool enhances user experience for Sumatra PDF users by simplifying file management without intermediary servers or rendering claims.
