Working with PDF files of huge size might consume a lot of time in loading and saving them and especially in attaching them with mails. It is important to reduce PDF size. By reducing the file size of a PDF, not only reduce your working time but also provide more storage space and make the transfer of files easy for you and for the recipient.
The factors that affect that affect the size of a PDF are image type, its resolution, font and how the fonts are embedded, the version of PDF and the compression level. The size of a PDF file can be reduced considerably by a PDF optimizer. Some of the techniques that are used to reduce PDF size with PDF optimizer are as follows,
Choose the Advanced option under PDF Optimizer. Select the Audit Space Usage button. The results of the audits show you the number of bytes used by images, bookmarks, fonts and helps you to decide on the effective way to reduce PDF size.
The file size and quality of the documents can be adjusted in the scanned pages panel using the adaptive compression slider when the PDF document is created using a scanner. Use the images panel to select the compression option when the PDF is not scanned.
Fonts occupy a lot of space. So unembedding the fonts helps you to reduce PDF size. Before you unembed the font, make sure that the font is available in the computer of the person who will be reading the PDF. If it isn't available then Acrobat itself will display a default font when the document is opened in another computer.
The images in the PDF can be compressed by editing them in Adobe photoshop or Adobe illustrator or in any other image editing software. The size of the image should be reduced before creating the PDF file.
Finally, save the optimized PDF file. You can either overwrite the optimized file on the original or create is as a new file.
Acrobat retains the PDF optimizer settings and they appear as default settings when you open the PDF optimizer the next time. Thus your PDF file has become compact and easier to use than ever before!
