  "account": "PDF compression works by squeezing individual objects within a PDF file, such as pages, text, fonts, and images, using specialized algorithms. This targeted compression allows different types of content to be compressed in their most effective manner. The resulting file is smaller because extraneous data, redundant information, and metadata are removed, while preserving the document's appearance and functionality.",
  "summary": "A PDF is not one solid block of data. It is a small filing cabinet: a set of objects — pages, text, fonts, images — held together by a table of contents. PDF compression works by squeezing each of those objects with the right method, then throwing away the parts nobody needs. That is why one PDF can shrink by 80% while another barely changes at all. Try the free PDF Compressor — shrink a PDF in…",
