# PDF Batch Compressor

## Functionality
This nifty utility compresses PDF files via [Ghostscript](https://www.ghostscript.com/) in the folder where this script resides:  

:one: Create a sub-folder, ./compressed, and put the resultant compressed ones in it,  
:two: Compress files with any PDF extentions i.e., .pdf, .PDF, .pDf and so on,  
:three: Optional compression parameter to be supplied, namely, prepress, ebook (default) and screen - in the descending order of quality, and  
:four: Log output with the compressed file names and any error message in the sub-folder

N.B. Make sure to make this script excutable via `chmod +x` or `chmod 755`, after downloading!
