What is PDF Compression?
PDF compression reduces your PDF file size while preserving as much quality as possible. It optimizes PDF files that are too large to email or share on the web.
PdfMetric's smart compression algorithm optimizes images within the file, removes unnecessary metadata, and restructures the file. As a result, file size can be reduced by 50-90%.
