zeropdfZero-dependency PDF generation and editing in TypeScript.

Build, inspect, tag, encrypt, merge, and incrementally edit PDFs with a small public API and browser-friendly Uint8Array output.

Get Started

API Reference

Generate precise PDFs

Create pages, draw text and vector paths, embed JPEG/PNG images, attach files, add outlines, and serialize deterministic bytes.

Edit existing documents

Parse classic and xref-stream PDFs, update metadata and form fields, append overlays, reorder pages, and preserve incremental history.

Build accessible output

Create tagged PDFs with semantic flow helpers, scalable report templates, structure trees, image alt text, role maps, language metadata, inferred structure bounding boxes, table helpers, and validation warnings.

Designed for library authors and product code

zeropdf keeps PDF workflows close to regular TypeScript: you compose a document, add pages and annotations, then write bytes wherever your runtime needs them.

import { createDocument, rgb } from "@criston/zeropdf";

const doc = createDocument({
  title: "Invoice"
});

const page = doc.addPage({ size: "A4" });
page.text("Invoice #1007", {
  x: 56,
  y: 780,
  fontSize: 18,
  color: rgb(0.13, 0.2, 0.34)
});

const bytes = doc.toUint8Array();

Start with the getting started guide, then use the API reference when you need exact option types.
