PDF files, developed by Adobe Acrobat, are a file format known for its security and portability. When they are loaded with a large amount of videos and images though, they balloon in file size, making it difficult to e-mail or share them with anyone. A PDF compressor is necessary in these situations in order to bring them down to a reasonable size and share them with other people. PDF compressors will do this using one of two methods and it is important to understand how each one works before using it. By compressing files, it is easier to email, open, and transmit files.
PDF Compressor: Lossy and Lossless Methods
PDF compressors operate using a lossy or a lossless method. Lossy method of compression will reduce the quality of objects within the file. These objects include video, graphics and images. The reduction in these objects’ quality will reduce the PDF size significantly. Lossless method will not alter the quality of anything within the file. A lossless PDF compressor uses programs such as Winrar or Winzip to make the PDF smaller. The file isn’t as small after a lossy compression but it may be small enough for your needs.
PDF compressor: Where to find the software
PDF compressors are available on the internet, though simple searches. A search will reveal many free and trial programs. These programs will be good for an evaluation period, but a commercial upgrade should be considered if you are looking for more options.
