Portable Document format (PDF) is the most widely used format for storing and transferring data. These files are known to be large, sometimes being over one or two MB in size. The large sizes make it nearly impossible to share the file, forcing you to downsize the PDFs size.
The size of a PDF file might depend on image resolution, font, and the compression level. There are different compression algorithms to reduce the size of the PDF. The correct compression algorithm that will be appropriate to your needs depends on your PDF file. You can also downsize PDF size with several other techniques as well. Zipping and unzipping the files have found to be an effective way in transferring the files, but sometimes it isnt enough.
This can also be used for large number of files, by using a batch process. Minimizing the font is another easy way to downsize PDF size. This will reduce the number of embedded fonts that usually occupies a large space in the file. Insert high quality images so that when the file is compressed the quality of the images will not be affected. The size of the images should be reduced before inserting them in the PDF document.
There are many applications that are available to downsize PDF size. The file size and the quality of the files can be decreased in the scanned pages panel using the adaptive compression slider when the PDF document is created using a scanner. First, check the number of bytes by checking audit space option in the software. It will display the number of bytes used by the fonts and images. When you save the file, choose the File-> Save As option. You can either save it as a new file or overwrite the existing file. Saving the downsized PDF will remove some of the unused elements in the file. Acrobat Distiller and a few Plug-ins are some of the other tools used to downsize PDF size.
