Reducing PDF size refers to the process of minimizing the file size of a portable document format (PDF) document. For instance, a large PDF document containing high-resolution images or graphics can be optimized to reduce its size without compromising visual quality, making it easier to share, store, and transmit.
Optimizing PDF size is vital because smaller files require less storage space, consume less bandwidth during transfer, and are quicker to open and process. One of the key historical developments in PDF optimization was the introduction of the “Optimize PDF” feature in Adobe Acrobat, which allows users to reduce file size by removing unnecessary data and compressing images and text.
