HTML to PDF Converter — Free Online Tool

Convert HTML to PDF Online — Free, No Upload Required

OptiDrop's HTML to PDF Converter is a free online tool that transforms your HTML code into a downloadable PDF document. Whether you are building an invoice template, generating a report layout, testing web designs, or creating printable documents from HTML, our tool gives you instant results. The split-pane interface shows your HTML source on the left and a live rendered preview on the right, so you can see exactly how your PDF will look before downloading.

How It Works

Simply paste or type your HTML code into the editor on the left side. The live preview on the right updates in real time as you type. When you are satisfied with the result, choose your preferred page size (A4 or US Letter) and orientation (Portrait or Landscape), then click Download PDF. The tool uses the jsPDF library to render your HTML into a high-quality PDF file that downloads directly to your device.

Full CSS Support

The converter supports inline styles, embedded style tags, and most CSS properties including fonts, colors, margins, padding, borders, backgrounds, Flexbox, and CSS Grid. This means you can create richly formatted documents with headers, tables, lists, images, and custom layouts — all from HTML and CSS code.

100% Private — Runs in Your Browser

Unlike many online converters that upload your code to a remote server, OptiDrop processes everything locally in your browser using JavaScript. Your HTML code and the generated PDF never leave your device. This makes it completely safe for confidential business documents, invoices, contracts, and any sensitive content.
