You can insert a PDF into Google Slides by converting it into images or creating a link to the same. This post covers both methods in detail.

If you insert the PDF into your PowerPoint as an image, you'll have to insert at most one page at a time. Visit Business Insider's Tech Reference library for more stories.

Insert a scanned image or photo into Google Docs After saving your scanned images, you can add them to Google Docs. We also have a workaround if you cannot convert your PDF file.

Select the PDF file you'd like to save as an image, and click "Insert." The PDF will embed in the Word file. Right-click on the image in the Word doc. Select "Save as Picture," and enter a file name.
