PDF files are extremely efficient when it comes to the need of distributing large documents, books and presentations. These files may be very bulky in size, but they yield the most accurate print quality and high resolution for projection and viewing. However, speed and efficiency becomes an issue while trying to dispatch a PDF file via E-mail or while uploading it onto a website. Large files uploaded on the web also take a very long time to open and download. Thus, there is a need to reduce or compress this file without compromising on quality.
There are several methods one can follow when it comes to reducing PDF files. One common method is to clean up the file by removing unwanted and unused items like bookmarks, links and embedded fonts from the PDF file. Sometimes, simply recreating that PDF file automatically removes unwanted elements and creates a reduced file with the same content.
The PDF optimizer in most PDF viewer software helps in reducing PDF files without corrupting its contents. When you choose this option, you must save the file as a compressed version of the original PDF file or you can overwrite the original by saving the file under the same name. An advantage with using this method is, when you use save as, a document for fast web view is automatically created. This feature allows individual pages to be downloaded at a much quicker pace. You can also use the audit command to view all possible options in reducing PDF files.
Generally, in a PDF document, the bulk of the file is contributed by images and embedded text. Modifying image qualities to a more balanced format or reducing image sizes also reduces the size of the PDF file. Furthermore, deleting unnecessary embedded fonts or un-embedding fonts will also help in reducing PDF file size.
Another method is by using the print option, where you can change the PDF setting to the smallest file size version. The file is converted to a much reduced size and saved on the system.
Thus, these methods help tackle problems that occur while attaching, uploading and downloading PDF documents.
