iText cannot render PDFs to images or screen. PDFluent can. This matters for preview thumbnails, document review tools, and any visual workflow.
iText's pdfXFA add-on handles XFA flattening only. PDFluent supports dynamic reflow, FormCalc scripting, and XFA 3.3 form processing.
PDFluent's WASM package (@pdfluent/sdk-wasm 1.0.0: 3.8 MB with Brotli, measured 2026-09-16) lets you process PDFs entirely in the browser without a server round-trip. iText is JVM-only.
PDFluent has bindings for Python, Node.js, C, and WASM. iText is Java and .NET only.
Rust has no runtime to start first. JVM startup adds latency to every cold invocation — a real cost in serverless environments.
PDFluent pricing is public. iText commercial deals require a sales call.
Years of Maven artifacts, Spring integrations, Jakarta EE support, and Java-native tooling. If your stack is JVM, iText fits naturally.
For open-source projects that can accept the copyleft obligation, iText 9 is genuinely free. No free-tier limitations on feature set.
iText runs in production across banking, government, and legal sectors. The edge cases have been found and fixed.
A broad ecosystem of first- and third-party plugins (pdfHTML, pdfOCR, pdfSweep, etc.) built on a stable extension model.
Backed by Apryse (formerly PDFTron), with dedicated enterprise support contracts and a large sales organization.
Choose PDFluent if you are building in Rust, need WASM/serverless compatibility, or want a commercial licence at a published yearly price, per organisation instead of per seat.
iText is a solid choice for Java or C# shops, especially when open source AGPL use is acceptable. It has extensive documentation and a large community.
If you're building on the JVM and don't need PDF rendering or XFA, iText is a proven choice — especially if you qualify for the AGPL license. If you need PDF rendering, XFA form processing, browser-side processing, or bindings for Python/Node.js, PDFluent covers what iText can't.
Free under the AGPLv3, or a commercial licence if you would rather not publish your own source.
