HTML to PDF Converter – Upload, Customize & Download High-Quality PDFs

Welcome to the HTML to PDF Converter by SpeedyUtils – a powerful, fast, and fully client-side tool that allows you to convert your HTML files into downloadable, print-ready PDF documents. Whether you're a developer, designer, student, or professional, this tool gives you complete control over your PDF output – from setting the DPI resolution to adjusting margins and choosing the paper size.

📂 How It Works

1. Upload or Paste HTML

You can either upload a valid .html file from your device or directly paste your HTML code into the input field. This gives you full flexibility whether you're converting a saved webpage or working with dynamic content.

2. Customize PDF Settings

Before generating the PDF, you can fine-tune every aspect of the output:

Page Size: Choose standard sizes like A4, A5, Letter, or define your own custom dimensions (in millimeters).
Orientation: Portrait (vertical) or Landscape (horizontal).
Margins: Precisely control top, bottom, left, and right margins to match print specifications.
DPI (Resolution): Set the document’s resolution from 100 to 600 DPI for sharp, detailed output.

3. Preview Before You Download

No more blind exports. The live preview pane uses an <iframe> to render your HTML exactly how it will appear in the final PDF. You can make edits, tweak margins or layout, and re-preview in seconds.

4. Generate and Download

Once you're satisfied, just click the Download PDF button. Under the hood, the tool uses html2pdf.js, a powerful JavaScript library that combines html2canvas and jsPDF to generate high-quality PDFs on the client side. The process is fast, secure, and doesn’t leave your browser.
