The Need for Compressing or Shrinking PDFs
PDF is a very useful format, and there are millions of PDF files on the internet, on local intranets and personal desktops that vouch for its wide acceptability. This popularity is mostly due to the fact that a PDF file retains its format, color and fonts irrespective of where and how it is accessed. This miracle is accomplished by metadata, which, as its name implies, is data that is created by the PDF authoring software "about" the actual data in the document.
Methods to Shrink a Huge PDF File
To shrink a huge PDF file you need to optimize it. Use the `Save As' command every time you save the file. This will overwrite the entire file and reduce file space. `Save' only appends the file and ends up increasing file size since it saves the latest changes. Prepare all the images by setting their resolution and cropping them to fit perfectly. You can use the `Advanced' menu to set compression levels for the images. Unwanted objects and unnecessary fonts can be deleted since they take up a lot of file space. If you have plenty of PDFs to compress then use a PDF compressor.
How Compression Tools Can Shrink a Huge PDF File
There are many PDF compressors available on the web of which you can download some free. Compressors use algorithms to shrink a PDF where JPEG2000 is applied for color images and JBIG2 for black/white images. A compressor either uses lossless or lossy compression methods. Lossless compression will retain the quality of the original file while some loss of quality occurs in lossy compression. Files that are compressed can be brought back to their original size by decompression. The compression tool you need largely depends on the size of your business. If you download any free tools make sure it is 100% clean and free from viruses and spyware. Online buyer guides are a good place to evaluate PDF compressors. You can read the latest reviews and ratings before you make your decision.
