Powerpoint and keynote presentations are convereted to pdf documents automatically when you upload them to Showell for optimal usage. Pdf's require less space and open faster than large Powerpoint or Keynote presentations.
During this conversion you might lose some visual elements such as custom fonts because Showell doesn't carry a license to that specific font. To avoid the loss of elements we recommend converting your presentations to pdf's before uploading them to Showell.
For PDF optimization we recommend that the original file doesn’t contain high resolution graphics or images. The smaller the original, e.g. Powerpoint file is, the smaller the PDF will also be. If you have a Mac computer you can also use PDF Squeezer that does great job when you need to optimize large PDF files. There are also online tools, that are free, for optimizing PDF files.
