The ElectronPdfService extension provides access to the Proton service for browser-based PDF rendering. (Proton needs to be installed separately.)

Historically, this extension provided access to the now defunct Electron PDF Service instead of Proton, hence its name.


The extension provides a handy way to access the Proton service via a RESTBase API endpoint .

And here's an example: PDF for the article about Berlin.


  • Install Proton
  • Install RESTBase, and set up a config similar to config.example.wikimedia.yaml. Adjust the PDF server URL to reflect your host & port.
  • Download and place the file(s) in a directory called ElectronPdfService in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php :
    wfLoadExtension( 'ElectronPdfService' );
    $wgElectronPdfServiceRESTbaseURL = '/api/rest_v1/page/pdf/';
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.


  • Once the extension is installed, the “⧼ElectronPdfService-download-label⧽” link in the MediaWiki sidebar will lead you to a new selection screen.
  • Click the “⧼ElectronPdfService-download-button⧽” button to get the PDF.
  • Note: if there is no alternative rendering method available on the Wiki, “⧼ElectronPdfService-download-label⧽” will immediately serve you the Proton rendered PDF without showing a selection screen.
