A PDF can become large because it contains embedded images, fonts, metadata, unused objects, editing history, or duplicate internal resources. A good PDF compressor does not simply blur the document or damage text. Instead, it optimizes the file structure, removes unnecessary data, and keeps the pages readable. That is why this page focuses on practical PDF compression for documents you still need to share, print, upload, or archive.
