What iText pdfOptimizer is
iText pdfOptimizer is a Java and .NET add-on to the iText Core PDF library for developers who need to optimize PDFs for file size or speed. It can compress embedded streams, combine duplicate font data, subset fonts, change document color space for printing, and create an optimization report. Image handling covers JPEG, PNG, TIFF, JBIG2, and JPEG2000; images can be scaled as well as compressed. Presets are High, Mid, Low, Lossless, and Custom, and a Custom profile is available for configurable optimization. The add-on can process multiple PDFs in a batch and reverse an optimization if the resulting file or image grows. It is distributed for Java through iText Artifactory and for .NET through Artifactory and NuGet, with API access and self-hosted deployment. The iText Suite, which includes the closed-source add-on, is offered with a 30-day free trial under a commercial license. Java installation requires a commercial iText Core license. iText also describes commercial and AGPL licensing; AGPL terms require disclosure of the application's full source code. Commercial technical support requires a valid support subscription, while AGPL users can seek community support on Stack Overflow.
