PDF files can sometimes be very large due to scanned images and pictures of high resolution in them. The main factors that need to be kept in mind while reducing PDF file size is: image type, fonts and how they are embedded, PDF version and lastly the level of size reduction.
It is frustrating to deal with files too large as they can take a lot of time to get attached to your mail. This is why you should follow the process of reducing PDF file size, which can be done with just a few clicks, saving time and providing you with files much smaller and easily manageable.
There are many ways of reducing PDF file size. One of the most common ways is to clean the file by eliminating all unwanted and unused bookmarks, links, embedded fonts, etc. This can be done by simply recreating the file with the same content.
Another method is to use the Save As command. This command overwrites the entire PDF file. If you click only save, changes you make are appended and this increases the file size leading to a larger file than the original.
The next option is the audit space usage. The Audit space usage provides information about the various elements in a file such as images and fonts. It also gives information about the number of bytes occupied by them. This provides the user an idea of the things that occupy a large space in the file and they can act accordingly.
If colors are not needed in the file, then one can use grayscale in reducing PDF file size. Reducing PDF file size helps in eliminating unnecessary pixel data and also lowers the resolution of images. For documents that contain only the standard font types, the font embedding option can be safely deselected. This too helps in decreasing the PDF file size
There are many advantages of reducing PDF file size such as faster emailing, searchable text, reduction in storage, data retention, lessens server load etc. Hence reducing PDF file size is a very important process and should be done in order to use PDF files effectively.
