How do I preview a SCORM package without an LMS?

Open a SCORM .zip file and the viewer launches the package launch page in a secure standalone player. You can navigate the content, test interactions, and view slide progression.

Can I view SCORM content in my browser?

Yes. The viewer runs entirely in your browser. It extracts the package, rewrites asset references, and renders the launch page in a sandboxed iframe with a simulated SCORM API.

Does the SCORM viewer support SCORM 1.2 and 2004?

Yes. The viewer detects the SCORM version from the manifest and provides the appropriate API (LMSInitialize/GetValue/SetValue for 1.2, or Initialize/GetValue/SetValue/Terminate for 2004).

Does the viewer track completion and scores?

The viewer simulates SCORM API calls locally. Completion, scores, and progress are tracked within the session but are not sent to any LMS. This lets you test the learner experience without an LMS.

Is my SCORM file uploaded when using the viewer?

No. The viewer processes the entire package in your browser using JavaScript. No data is sent to any server.

Can I view a SCORM package offline?

Yes. Once the package is loaded in the viewer, it stays in browser memory until you close the page or load a different package. No network connection is needed after loading.
