PDFluent is a PDF SDK built on a pure Rust core (48 crates, zero C or C++ dependencies). This means no native library to link and a single dependency to vendor. The Rust core is reached from Python, .NET, Java and Node.js through native bindings, and is compiled to WebAssembly for the browser (2.5 MB brotli-compressed over the wire).

You can integrate PDFluent from Rust, Python, .NET, Java, and Node.js, with packages published on crates.io, PyPI, NuGet, Maven Central, and npm. The SDK covers the full spectrum of PDF operations:

  • Rendering, text and image extraction
  • AcroForm forms and PAdES digital signatures
  • PDF/A conversion and validation, redaction, OCR
  • Document manipulation: merge, split, watermark, compress
  • XFA form rendering and flattening (experimental)

PDFluent has been tested on 50,000 real PDFs with zero crashes. In a rendering fidelity benchmark of 5,000 PDFs, 94% achieved SSIM 0.95 or better against the reference renderer mutool.

Run the SDK with no licence key at all and you get every feature plus a Producer watermark on output. Take the 30-day evaluation, no credit card required, and the watermark is gone for those 30 days. Buy a perpetual licence (paid once from EUR 699 โ€“ no subscription) and it stays gone.

A companion desktop editor for macOS and Windows is free for everyone, including commercial use. It runs entirely on the device, requires no account, and sends no telemetry. The company behind PDFluent is Innovation Trigger B.V., based in the Netherlands.

Questions & Answers

As answered by people managing Parascript and PDFluent SDK.

How would you describe the primary audience of your product?

PDFluent SDK's answer:

This fits developers who need to process real-world PDFs that include XFA forms - often from government or banking sources - and want a single SDK that works consistently across Python, Node.js, Java, C, Rust, and WebAssembly without managing native binaries for each platform.

What makes your product unique?

PDFluent SDK's answer:

PDFluent SDK parses XFA, a 1,000-page specification that almost every modern PDF library ignores. It evaluates FormCalc scripts and flattens XFA forms to standard PDF, validated against an internal corpus of 1,150 enterprise documents including US, Canadian, IRS, GSA, and VA government forms plus banking documents. XFA support is experimental and has no published fidelity claim.

Why should a person choose your product over its competitors?

PDFluent SDK's answer:

Because the SDK is pure Rust with no C or C++ dependencies, there is no FFI boundary inside the engine, no C++ exceptions to catch, and no platform binary to ship per OS. This eliminates the deployment complexity of dragging in a full PDFium build.

What's the story behind your product?

PDFluent SDK's answer:

The team got tired of PDF libraries that crashed on real-world documents, ignored XFA entirely, or shipped 80 MB of C++ just to read a form field. They started building a parser in Rust from scratch, then added an XFA engine, a renderer, and a PDF/A converter. The company is Innovation Trigger B.V., based in the Netherlands.

Which are the primary technologies used for building your product?

PDFluent SDK's answer:

PDFluent is built in pure Rust with no C or C++ dependencies. It provides bindings via PyO3 for Python, napi-rs for Node.js, JNI for Java, a cdylib header for C, native Rust, and WebAssembly (2.5 MB brotli-compressed). The same engine runs across all surfaces.
