What is PDF Compression?
PDF compression is the process of reducing the file size of PDF documents while maintaining their visual quality and readability. Our advanced compression algorithm analyzes your PDF's internal structure and optimizes it by compressing embedded images, removing redundant data, and streamlining the document's encoding. This results in significantly smaller files that are easier to share via email, upload to websites, or store on cloud services.
