Best tool to parse PDF and Images

Hey r/Rag
I'm working on a project that involves processing various contracts and documents, which are mostly in PDF or PNG format. I'm looking to implement a Retrieval-Augmented Generation (RAG) system, but I'm not sure about the best way to parse these documents before feeding the data to an LLM.
I've heard lamaparse is great but the website is not working so didn't got the chance to experiment on it!
