Known limitations

PDFluent is a public beta. APIs may shift before 1.0. Pin the version you ship and read the changelog before upgrading.

Flatten of XFA forms to static PDFs is reliable and is the recommended production path. Live rendering of complex dynamic XFA forms can produce visual deltas against Adobe Reader; the golden-image set we measure against is improving wave over wave.

The PDF/A converter and validator cover PDF/A-1b, PDF/A-2b, and PDF/A-3b. Other PDF/A profiles (1a, 2a, 2u, 3a, 3u, 4 and its family) are scoped for later releases.

Pre-built binaries cover the common platforms in each channel. Less common architectures or runtimes may need a build-from-source step during the beta — check the channel page for Rust, Python, WASM / JS, .NET, or Java.

The homepage cites a cold-start multiplier and a memory headroom multiplier. These come from an internal benchmark corpus. Published benchmark methodology is scoped for a later wave; until then, treat these as directional, not contractual.

PDFluent is not a drop-in Adobe Reader replacement. We do not claim full Adobe rendering parity. We aim for reliable flatten, reliable text extraction, reliable PDF/A conversion, and improving render fidelity wave over wave.
