Export Google Slides to Image / PDF

I'm trying to turn Google Slides into PDF or IMAGE format, and I'm having a lot of trouble finding a solution that is not 10 years old and still working.

Here is how I did :

Doesn't matter the way you're going, you NEED to add the services "Google Slides API" !! enter image description here

If the script is linked to the presentation, you can use the following :

FOR PDF

function toPDF() {
  const folderId = "1-rCYyDgTzOV0FKt2gdh8dtaB1hSi1JN-";
  const presentation = SlidesApp.getActivePresentation();
  const slides = presentation.getSlides();
  let temp = SlidesApp.create("Temporary");
  const id = temp.getId();
  const file = DriveApp.getFileById(id);
  const folder = DriveApp.getFolderById(folderId);
  slides.forEach((slide, i) => {
    temp.appendSlide(slide);
    temp.getSlides()[0].remove();
    temp.saveAndClose();
    folder.createFile(file.getBlob().setName(i + 1));
    temp = SlidesApp.openById(id);
  });
  file.setTrashed(true);
}

FOR IMAGE

 function toPNG() {
      const folderId = "1G6E_BZeilLJ1_f36xpwFqlthXblGOI3h";
      const presentation = SlidesApp.getActivePresentation();
      const id = presentation.getId();
      const slides = presentation.getSlides();
      const folder = DriveApp.getFolderById(folderId);
      const options =  {"thumbnailProperties.mimeType": "PNG" };
      slides.forEach((slide, i) => {
        const url = Slides.Presentations.Pages.getThumbnail(
          id, 
          slide.getObjectId(),
          options
         ).contentUrl;
        const blob = UrlFetchApp.fetch(url).getAs(MimeType.PNG);
        folder.createFile(blob.setName(i + 1));
      });
    }

If you want to use the code from a bigger script (outside of the script linked to the google slide document), then you can use this :

FOR IMAGE :

/**
 * Converts all slides of a Google Slides presentation (specified by its ID) to PNG images
 * and saves them to a specified folder.
 * 
 * @param {string} slideFileId - The ID of the Google Slides presentation to convert.
 * @param {string} folderId - The ID of the folder where the PNG images should be saved.
 */
function convertSlideToPNG(slideFileId, folderId) {
  // Get the specified presentation by its ID
  const presentation = SlidesApp.openById(slideFileId);
  
  // Get all slides in the presentation
  const slides = presentation.getSlides();
  
  // Get the target folder by its ID
  const folder = DriveApp.getFolderById(folderId);
  
  // Define the options to get the slide as PNG
  const options = { "thumbnailProperties.mimeType": "PNG" };

  // Loop through each slide and generate its thumbnail
  slides.forEach((slide, i) => {
    const url = Slides.Presentations.Pages.getThumbnail(
      slideFileId,
      slide.getObjectId(),
      options
    ).contentUrl; // Get the URL for the PNG thumbnail
    
    const blob = UrlFetchApp.fetch(url).getAs(MimeType.PNG); // Fetch the image as PNG
    folder.createFile(blob.setName('Slide_' + (i + 1) + '.png')); // Save the PNG in the folder with a slide-based name
  });
}
