Load Time

[defaultddy3ra2n7jp6]

I created a presentation and it is taking a long time to load, export, etc. The reason is I created a pattern using a large number of small logos. Is there a way to expand a pattern in Express so it's no longer a vector? I think I'm using that terminology correctly, but not sure. I tried to compress the file after downloading it, but it made some of the pictures I added blurry.

I downloaded it as a png and then added each slide to a pp deck. Works fine, just can't download it as a pdf.
