What is a PDF?
PDF (Portable Document File) is a popular file format designed to retain all file components such as the text, images, typefaces, layout as-is, irrespective of operating system, hardware and viewing software. It is basically a data container to hold both text and images in an unchanging format. PDF format is preferred for being compact, secure and easily portable as its name suggests.
How Does PDF Compression Work?
PDF compression helps in handling large volumes of documents and saving memory space, by reducing the size of the file using appropriate compression algorithms. PDF compression is performed on both text and image to avoid the file from becoming too large. A variety of file compression methods are designed to reduce the file space used by color, grayscale, and monochrome images in PDF. The default Adobe PDF Settings uses automatic (JPEG) compression for color and grayscale images and CCITT Group 4 compression for monochrome images and applies Flate compression to all text and line art in the document, without loss of detail or quality. Bitmap images can be re-sampled to reduce the file size. PDF compression algorithms mentioned above are classified under Lossy (lose some information upon compression) and Lossless (do not lose any information contained) which are applied based on user requirements.
What are the Advantages of Free PDF Compressor Download?

Using PDF compressor is convenient and faster when attaching the files for email thereby avoiding network clog due to large files. Compressing files allows easy reduction of the documents sizes. Compressing PDF size also helps in saving storage space and time for downloading or organizing the files. The files are more easily accessible and can be shared by people across the network. Data exchange is faster and saves time and cost for the user. PDF compressor does not reduce the content quality or the PDF security features.
