What iText pdfOptimizer is
iText pdfOptimizer is a Java and .NET add-on for the iText Core PDF library, aimed at developers optimizing PDFs for size or speed. It can compress embedded streams, merge duplicate fonts, subset fonts, change document color space for printing, and produce an optimization report. Image optimization covers JPEG, PNG, TIFF, JBIG2, and JPEG2000, with options to scale or compress images. Presets include High, Mid, Low, Lossless, and Custom. The add-on can process multiple PDFs in a batch and reverse an optimization if the resulting file or image becomes larger. Java distribution is through iText Artifactory; .NET distribution is through Artifactory and NuGet. The iText Suite, including this closed-source add-on, has a 30-day free trial under a commercial license, but the Java installation guide requires a commercial iText Core license. iText also describes commercial and AGPL licensing; AGPL terms require disclosure of the full application source code. Commercial technical support requires a valid support subscription, while AGPL users can use community support on Stack Overflow.
