PDF files are the most popular way to share documents, brochures and other information over the internet. The benefit of PDF files is that they are system independent, they look same no matter in which program or operating system you view them. If you intend to share your PDF files over the internet, then you would want to make them smaller as smaller size files are easier to download and take less bandwidth of your webserver. You can use the free Orpalis PDF Reducer software to reduce the size of your PDF files and customize them.
You can download PDF Reducer from the Orpalis website. The download is a setup installer of around two megabytes. After the installation, you can launch it from its desktop shortcut, Start Menu or from the Windows 8 Search Charm. PDF Reducer has a straightforward user interface. You select source PDF files (you can select multiple PDF files in the same time), choose a source folder (where the output files would be saved), select the number of threads you want to give to the PDF Reducer program (more threads makes it faster) and finally click on the Start batch button to start the reduction process.
The PDF reduction program is very fast. It compresses each page of the PDF files and makes them smaller. You can see the progress of what is happening in the PDF Reducer window. In the end, a summary message would be shown about how much reduction was achieved using the reduction process.
If you click on the Options in the menubar, it would open the Options window where you can customize how the final PDF files are produced. You can set options for enabling color detection, recompression of embedded images, removal of unused objects, reducing image quality etc. You can also choose if some type of content is to be removed (like annoations, form files, bookmarks etc.). You can choose a PDF version for the output files and whether to optimize the PDF files for fast web view.
PDF Reducer is a free and fast software that allows you to reduce the PDF file sizes. It can achieve the compression through a multitude of optimizations and compression levels. It can re-compress the embedded images in such a way as to reduce their size without affecting the quality that much. For my files, it could compress them to around 90% of the original file size. Even if the compression is small, it can reduce your webserver bandwidth significantly if you want to distribute the PDF files through your website.
