What's the easiest free app to use to convert 1093 pages of pdf to text?

Hi everybody. Can anyone tell me the name of a free, easy to use MacOS app to use to convert 1093 pages of pdf to text? I am in a dispute with a contractor, because of which I made a public records request about the contractor to our state Construction Contractor's Board, in response to which I received 1093 pages of pdf I can't read.

I did do a search on the applevis web site but didn't find what I was looking for.

Best,

Bruce
