The Problems of Unoptimized PDFs
PDFs, or Portable Document Files, are some of the most ubiquitous files when it comes to digitizing documents. They are a versatile file format that matches high compatibility across computer platforms with ease of use and compact size. However, the size of a PDF is highly dependent on how optimized it is. Unoptimized PDFs will be massive and ungainly, resulting in document files that can be dozens of megabytes in size. Such unoptimized PDFs are unsuitable for upload or for e-mailing to others. If you want to make the most of what PDFs have to offer, you will need to use a PDF optimizer.
PDF Optimizer Software and How It Works
A PDF optimizer works by stripping all extraneous data from a PDF file and compressing or packing it in the most efficient way possible. The PDF optimizer works on two major facets of the file: text and images. When working with images, the PDF optimizer compresses the picture by using algorithms to reduce the amount of information in the PDF while still maintaining a high level of picture quality. The best programs will create an optimized image that cannot be distinguished from the original one. A PDF optimizer will also convert the text in your PDF document from a simple image of the words (such as what a fax machine or copier will do) into text data that both a computer and a human can read. This does not change the content of the document, but makes the document itself much smaller.
Choosing the Best PDF Optimizer
When looking for a PDF optimizer, one must be careful. There is a trade-off between document quality and document size. Lesser programs may reduce the size of your PDF but reduce quality to an unacceptable level. The best PDF optimizer will reduce size but still maintain quality.
