They usually require a PDF compression software, which can be either online or desktop. Of course, these compression algorithms won’t happen by themselves. The end result is a compressed image, but with reduced file quality. Lossy is mainly for images and graphics, as it reduces file size by eliminating bits of information.Lossless is used for documents containing text, as its algorithm creates reference points for textual patterns, stores them in a catalog and then brings them back to your file.This article further explains these two types of compression, however you should note the main difference: Well, the same is for digital documents, except in this instance, you don’t necessarily have to lose too much quality as here we have a lot more compression options.įor example, PDF documents are naturally optimized for compression.The PDF, by default, supports two biggest compression types: lossless and lossy. That can be seen in compressing JPEG images in Photoshop: the more you reduce the image file size, the worse the quality gets. Unfortunately, that compression is often done at an expense to file quality.

Generally speaking, compression is a process through which we optimize bits and bytes in order to reduce overall file size and “fit things better”. If you’re not sure how to compress a PDF so that you can share and store it more easily, then you’ve come to the right place.īut, before we go on to the tutorial, let’s explore what exactly PDF compression implies.
