Forms Upload - File Too Large

I have completed security forms for an agency and when I attempted to upload them online, the website says the PDF is too large. Anyone else ever have this problem? I provided some lengthy explanations that I do not want to delete. I have contacted my recruiter, but was surprised that the website would not allow the uploading of a larger file. Additionally, the printed version that I must mail in has cut off some of my answers, despite being allowed to write as much as I wanted on the electronic copy.

Haven’t had this issue but maybe break it up into different pages. Upload one page at a time and attach each document.
