Our verdict on iText pdfOptimizer

iText pdfOptimizer is a developer-focused add-on for the iText Core PDF library, intended for teams embedding PDF optimization into Java or .NET applications. It can optimize PDFs for file size or processing speed through configurable handlers for streams, fonts, images, document structure, and color spaces. API and self-hosted deployments suit automated document workflows, while integrations include iText Core, Java, C#/.NET, Maven, and NuGet.

Compression control is a central strength. Preset profiles cover high, mid, low, and lossless compression, with custom profiles for more specific requirements. Image optimization supports JPEG, PNG, TIFF, JBIG2, and JPEG2000, including configurable quality and scaling. The product can remove duplicate fonts, subset fonts, compress embedded streams, and convert color spaces between CMYK and RGB. Size checking can revert an optimization when the output grows, and custom reports help teams review processing results.

The licensing structure supports both open-source and commercial use. The Open Source AGPLv3 license is available for Java and .NET, supports an unlimited number of PDFs, and requires disclosure of the application's full source code. Commercial options include an OEM Distribution License with custom pricing and conditions based on the business and deployment option, plus an annual Subscription License Volume priced according to the quantity of PDF files processed. Teams needing embedded, repeatable optimization should consider iText pdfOptimizer; organizations seeking a standalone browser-based compressor should look elsewhere, as the separate free online demo is not the same product.
