Which method is used to share Power BI reports with external users?

The method used to share Power BI reports with external users is publishing to the web. This feature allows users to create a public URL for their reports, making it accessible to anyone with the link, including individuals who do not have Power BI accounts. This approach is particularly useful for sharing non-sensitive data widely or for demonstrating insights during presentations or on public websites.

Publishing to the web generates an iframe code that can be embedded in a website, allowing broader access without requiring users to log in, which is what makes it ideal for reaching external audiences. It expands the reach of reports beyond the organization, facilitating transparency and information dissemination.

The other methods mentioned serve different purposes. While embedding in websites can also be effective for sharing reports, it typically requires a Power BI account for access unless published to the web. Sending files via email and exporting to PDF are methods focused on sharing static snapshots of reports rather than keeping them interactive and up-to-date. These alternatives do not provide the ongoing interactivity and accessibility that publishing to the web accomplishes, especially for those who are external to the organization.
