**By activating the service workers, transform your web app into a Progressive Web App (PWA) in just one click.**

The Progressive Web App (PWA) is a web application that offers a user experience similar to a native application. Technically, PWA uses service workers to manage requests and caching. However, these service workers are not supported by all operating systems and browsers in the same way. If a device is not compatible, your application will function as a classic web app for the user.

## Activate the progressive web app

- On your web app page, click **Settings**, then open the **Web Settings** tab.
- In **Progressive Web App**, turn on **Service Workers**, then click **Save Changes**.

The **Full Loading** option ensures that the application has been fully downloaded during its first use and that users will therefore be able to access it offline.

Users will be able to [add the app to their home screen](https://docs.pandasuite.com/essentials/web-publishing/add-your-pwa-to-home-screen/).

## Browser compatibility

A PWA relies on service workers. Every browser that can run a PandaSuite web app supports them:

| Browser                                              | Compatible version                  |
| ---------------------------------------------------- | ----------------------------------- |
| Chrome (desktop and Android)                         | 87 and later                        |
| Edge                                                 | 88 and later                        |
| Firefox (desktop and Android)                        | 78 and later                        |
| Safari (macOS, iOS, and iPadOS)                      | 14 and later                        |
| Browser built into another app, on Android (WebView) | Android System WebView 87 and later |
| Browser built into another app, on iPhone or iPad    | Usually not supported               |
| Internet Explorer                                    | Not supported                       |

These are the minimum versions of the web app itself: see [HTML5 compatibility](https://docs.pandasuite.com/essentials/web-publishing/html-5-compatibility/). On iPhone and iPad, a web app opened from a link in another app (messaging, social network...) often opens in that app's built-in browser, which does not run service workers: open it in the device's browser instead.
