Convert TXT to PDF Securely (100% Offline)

How to convert TXT to PDF offline

The Privacy Advantage: Zero Server Uploads

When dealing with highly sensitive documents—such as personal notes, legal drafts, code snippets, or confidential data—uploading your files to traditional online PDF converters poses a significant privacy risk. Once your file hits a remote server, you lose control over who sees it and how long it's stored.

The Solution: Zero-Knowledge Architecture.
Our TXT to PDF Converter is engineered with a strict client-side-only approach. When you drag your text file into the browser, the document is read and converted to PDF entirely using your device's memory. Premise: Your files cannot be intercepted or stolen. Evidence: You can disconnect from Wi-Fi immediately after the page loads and the conversion process will still work flawlessly. Conclusion: This is the safest way to convert TXT to PDF online.

Why Choose Our Text to PDF Converter?

Beyond unmatched privacy, our converter solves a common frustration for developers and technical users: formatting loss.

Standard converters often use basic fonts that fail to render technical symbols, ASCII art, or directory trees. Our tool natively embeds the Hack-Regular developer font, ensuring that complex UTF-8 characters, mathematical operators, and box-drawing symbols (like ├──) are preserved pixel-perfectly in the final PDF.

import { PDFDocument } from 'pdf-lib';
import fontkit from '@pdf-lib/fontkit';

async function generateTxtToPdf(textData, fontBuffer) {
  // 1. Initialize Document & Register Fontkit
  const pdfDoc = await PDFDocument.create();
  pdfDoc.registerFontkit(fontkit);

  // 2. Embed the Custom Developer Font
  const customFont = await pdfDoc.embedFont(fontBuffer);

  // 3. Add a page and draw text
  const page = pdfDoc.addPage();
  page.drawText(textData, {
    x: 20,
    y: page.getHeight() - 20,
    size: 12,
    font: customFont,  // Now supports ASCII art!
    lineHeight: 14,
  });

  return await pdfDoc.save();
}
