Can You Shrink a PDF?
With the Portable Document Format or PDF you can view information created in any application. If your PDF files are too big then you need to shrink them in order to save on storage, and increase uploading/downloading speed. A large number of graphics, multiple fonts and styles, along with video and audio embedded in a document can increase file size to a great extent. On conversion to PDF the file size further increases. When the question of can you shrink a PDF crops up, the answer lies in PDF compressor tools. You can reduce file size with the help of a PDF compression tool. There are also several precautions that you can take to keep file size to the minimum.
How Compression Tools Can Shrink a PDF
A host of freeware PDF compression tools are available online and can be downloaded free. A compressor uses algorithms to shrink a PDF. If you use a free tool make sure you download a 100% clean program that does not contain any form of malware, including viruses, Trojans, and spyware. Images are compressed with JPEG2000 for color images and JBIG2 for b/w pictures. Compressed files retain their original format. A program either incorporates lossless or lossy compression. In lossless compression the quality of the PDF remains the same. In lossy compression there is a loss of quality when a file is decompressed. What type of tool you need to shrink a PDF depends on the volume of compression job you have on hand. Look for software that has been tested and certified.
Methods to Shrink a PDF
Apart from PDF compression tools you can also shrink a PDF using the `Save As' command to save the file. This will reduce file size because this function overwrites the entire file. Using only `Save' increases file size since it only saves the latest changes made. You can use the `Advanced' menu options to change the compression settings for images. Deleting all unwanted objects and unnecessary fonts will reduce the size of a PDF. All images can be compressed and resized individually to save maximum file space. If you need to shrink PDFs frequently then make sure to pick a good PDF compression tool. Compromising on quality will only make your problem more complex.
