Web Map imported shapefile too big despite having 1 feature and 4 MB size?

Hi! I'm having some serious issues importing a shapefile to use as a layer in a WebMap. The shapefile shows a plant species' range, and is very large (over 10000 features, and 25 MB). When I eliminate polygons smaller than 5 KM using Select by Attribute/export to shapefile, Dissolve the shapefile, and use Simplify Polygon, I can get the shapefile down to 1 feature and 4 MB, but when I try to import it in the Web Mapping interface, I still get a "file too big" error message.

Is there a way to fix this? Any suggestions are greatly appreciated! This is for an assignment due Tuesday, May 31, so I'm pretty stressed about it.

I've attached the error message

From the help topic... zip it

It was zipped; you cannot upload an unzipped shapefile.

I've resolved the issue by bringing down the number of features by using a Select by Attribute query (NOT using Dissolve - that doesn't appear to work very well) and using Simplify Polygon. The result is very rough, but works for my purposes.
