Either unembed all fonts or the subset of fonts.Initialize OptimizationOptions class object.You need to follow the following steps to optimize and reduce PDF file size: These PDF optimizations will reduce the file size considerably. Moreover, you can remove unused streams or link duplicate streams to save further space. It would be a partial unembedding of fonts that would still help in minimizing the file size. For example, you can either unembed all the fonts or you can keep only the subset of font characters that are being used in the PDF file. Embedded fonts can help reducing file size with different approaches. When you need to reduce PDF file size then every byte matters. The code snippet below shows how to shrink or compress images in order to reduce and minimize the PDF file size using Java: Removing Embedded Fonts, Unused Streams and Linking Duplicate Streams using Java # You need to follow the steps below in order to shrink, compress and resize the pictures or images in a PDF file: The size improvements could be noticeable because most of the file size is covered by the pictures that we now intend to shrink. You can minimize the size of PDF file containing many images by shrinking, compressing and resizing the images. In such scenarios, we can compress the PDF files with following approaches: Shrinking, Compressing and Resizing All Images using Java # Moreover, many professional documents could contain images as major artifacts of the file. For instance, a PDF file containing drawing for different models of airplanes and information about each part, minor or major, included as images or pictures of all components. Here we will mainly be discussing the scenarios where PDF files contain a lot of images thus are huge in size. The code snippet below is an example of how to optimize PDF documents for the web in your Java environment: Compress or Optimize the Size of PDF containing Images using Java # Call optimize method for PDF Optimization. You can have the optimized PDF file by following the steps below: This optimization is helpful to display the first page of PDF document as quickly as possible. PDF document can be optimized when you need to use them in your web pages. Optimize PDF Documents for the Web using Java # You can download the JAR files from Downloads or with Maven configurations in your project. You can utilize the efficient and reliable routines of Aspose.PDF for Java API for optimizing or compressing huge-size PDF files while keeping the same quality.
