FyTek's PDF Optimizer allows you to optimize, or linearize, your PDFs for faster viewing on the web. When combined with a web server that supports byteserving, optimized PDFs display the first page without waiting for the entire PDF to transfer to the user's browser. This can save considerable time over a slow link when displaying PDFs. In addition, you can secure your PDFs with PDF Optimizer. This allows you to apply 40 or 128-bit encryption, password protection and disable certain features.Only large PDFs that are viewed on the web need to be optimized. You do not need to optimize PDFs to view locally or to email. Optimizing refers to speed optimization for web viewing only and does not mean the PDF is optimized for file size. PDFs that are optimized are typically slightly larger than their non-optimized version due to extra information that must be stored to support optimization. Note that the web server itself must support byteserving.
