ORPALIS PDF Reducer Professional 3.0.27 (19.41 Mb) is a category of applications, functionality that is fully explained in their name. As you might expect, this tool is designed to compress PDF documents before they are published on websites, sent to repositories or sent via email. The application interface is simple and easy. All you need to do is select a source document, specify a folder to save the optimized version, and click on the “Start” button. All other actions will be done without your participation. However, the SoftwareCrew site reviewer, who conducted a thorough product testing, warns that ORPALIS PDF Reducer does not always address the task well. In some tests, the size of the document remains virtually unchanged, but in some cases the compression rate can reach an impressive percent. The essence of this product is a fairly simple technology. The program achieves the desired result by manipulating the DPI characteristics (number of dots per inch) and re-compressing the document with a slight decrease in image quality. In the processing of ORPALIS PDF Reducer also eliminates some less important elements of the document, such as form fields, annotations, bookmarks, embedded files. However, if this approach seems unacceptable to you, you can manually configure the cleanup parameters in the “Settings” dialog box. A separate mention is worth processing the possibility of processing large numbers of files in batch mode.
To achieve that, ORPALIS PDF Reducer provides different innovative and highly sophisticated size-reducing techniques which can be optionally applied by user selection:
- Content segmentation to increase compression ratio.
- Automatically applies the most effective compression scheme based on data type.
- Serialization of several compression algorithms.
- Uses innovative automatic color detection mechanism.
- Page layout analysis.
- Embedded raster images re-sampling.
- Embedded raster images re-compression.
- Unused objects removing.
- Remove unwanted specific objects such as annotations, bookmarks, formfields, embedded files…
