• 🖥️ Web app - site/ is a static, browser-only PDF → UDF converter in Turkish and English. GitHub Pages serves it through .github/workflows/deploy.yml, and conversion runs fully client-side.
• 📚 Node library - converts PDF documents into UYAP UDF files. It rasterizes each page to a 200 DPI PNG and embeds it as a full-page image, so the output looks exactly like the source. Line spacing, table widths and lost headers/footers, the usual problems of text-based converters, cannot happen here.
• 🔁 No system dependencies - PDFium compiled to WebAssembly renders the pages, so a plain npm install is enough on macOS, Windows and Linux. For Word documents, export to PDF first (File → Save As → PDF), then convert.

npm install uyap-udf

import { readFile, writeFile } from "node:fs/promises";
import { convertPdfBufferToUdf } from "uyap-udf";

const pdf = await readFile("document.pdf");
const outcome = await convertPdfBufferToUdf(pdf);
if (outcome.ok) await writeFile("document.udf", outcome.udf);

convertPdfBufferToUdf never throws for expected failures; it returns { ok: true, udf } or { ok: false, error }.

Other exports: rasterizePdfPagesToPng, pxToPt, zeroUdfPageMargins.
