pdf-render

PDF page rasterizer in pure Rust — vello-backed rendering, no PDFium, WASM-compatible.

This crate is part of the PDFluent commercial Rust PDF SDK.

Free for evaluation. Production use requires a valid license.

What it does

Rasterizes PDF pages to raster images (PNG, JPEG, raw pixel buffers). Uses vello_cpu for content-stream rendering — no C++ dependency, compiles to WebAssembly, and produces output with high SSIM fidelity vs PDFium on the standard benchmark corpus.

Status

Beta. Median SSIM ~0.98 vs PDFium oracle on the 1000-PDF benchmark; 87% of pages score ≥0.95 (production threshold). Improvement work continues on near-miss cases.

Usage

Most users do not depend on this crate directly. Use the pdfluent facade or pdf-engine:

use pdfluent::prelude::*;
