How to Shrink PDF Size Few Simple Techniques
Reducing the size of PDF files will reduce almost all the problems in transferring files through email. PDF files are normally large in size, especially if they contain images and graphics. This will waste your time waiting for PDF files to get transferred through email. It is therefore indispensable to compress PDFs. But then, how to shrink PDF size? Here are a few simple techniques to shrink the size of PDF files. You can use the "Save As" command instead of "Save" command in the file menu. This will rewrite the PDF file after removing some unused items in the file. If you want to learn how to shrink PDF size effectively, you can also use PDF optimizers to shrink PDF. They can identify the objects that occupy more space and will make your work easier in reducing the size of the PDF file.
Compression algorithms are widely used to shrink PDF. If you want to know how to shrink PDF size you have to know different algorithms used to do it. The different types of algorithms, mainly compress the image content in the files either by employing lossy or lossless format. The lossy algorithms will compress the file to a large extent but with some loss in quality of the image. On the other hand, the lossless algorithms have a lesser compression ratio with greater content quality. JPEG and JPEG2000, ZIP, CCITT G3/G4,RLE, Flate,JBIG2 are some of the commonly used algorithms.
Image Size Reduction in PDF
The images occupy maximum space in a PDF file. If high quality images are used in the file, they can be replaced with JPEG images which are smaller in size. You can also down sample images to reduce the size. Optimizing the print quality can be another way out if you are wondering how to shrink PDF size. For normal quality printing 300 DPI is used, and for high quality printing 1200 DPI is used. If the print quality is high, the size will also be high. So, it is important to optimize it properly.
