iText pdfOptimizer
Ghent, Belgium
What it is
iText pdfOptimizer is a Java and .NET add-on for the iText Core PDF library that optimizes PDFs for size or speed. Developers can use it to compress embedded streams, merge duplicate fonts, subset fonts, convert document color space for printing, and generate an optimization report. Image handling supports JPEG, PNG, TIFF, JBIG2, and JPEG2000, with options to scale or compress images. Preset profiles are High, Mid, Low, Lossless, and Custom. The add-on can process multiple PDFs in a batch and revert 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 the closed-source add-on, has a 30-day free trial under iText’s commercial license. Java installation requires a commercial iText Core license. iText also describes AGPL licensing, whose terms require disclosure of the full application source code. Commercial technical support requires a valid support subscription; AGPL users can seek community support on Stack Overflow.
