PDFluent SDK

Pure-Rust PDF SDK for rendering, text extraction, forms (AcroForm + experimental XFA), PDF/A validation, digital signatures (PAdES), redaction, and document manipulation — with bindings for Rust, Python, Node.js, .NET, Java, C, and WebAssembly.

import pdfluent

doc = pdfluent.open("invoice.pdf")
text = doc.pages[0].extract_text()
doc.save("invoice-out.pdf")

use pdfluent::Document;

let doc = Document::open("invoice.pdf")?;
let text = doc.page(0)?.extract_text()?;
doc.save("invoice-out.pdf")?;

The SDK runs in Trial mode with zero configuration — every capability is available, output carries a /Producer watermark until you activate a license. See Licensing.
