Compressed PDF documents requires less disk space for storage and faster uploads and downloads saves transmission time and cost. The PDFOptim gives you access to compression options to help you to reduce PDF file size without compromising the document's integrity. PDFOptim rewrites the entire PDF documents using selected compression options as efficiently as possible. Some PDF documents might not get compressed, because the PDF documents might be already compressed or have nothing much to compress.
If your PDF documents are in another app (For Example Mail, DropBox or SkyDrive etc.) that uses the Open In… button, tap the button to open the PDF document in PDFOptim. You can also transfer PDF documents from your desktop computer via iTunes into PDFOptim application on your iPhone or iPad.
KEY FEATURES:

◆ JPEG quality control. Set quality from lossless to least for resampling all raster images into PDF. It allows you to control optimized PDF size and viewing quality.
◆ Image resolution ppi (pixels/inch) control to resize raster image contents. Downsampling at lower resolution decrease the file size dramatically.
◆ Image color model to choose from RGB, Gray and Mono. Selecting Monochrome color model compression option converts raster PDF contents into black and white which helps reduces PDF file size to greater extent. It is very helpful when compressing scanned books mainly containing text. Optimizing PDF using Monochrome color model can create 24 times smaller PDF compared to RGB color model compression.
