Convert HTML code to high-quality PDF documents. Paste your HTML into the editor or load an .html file, configure page settings, preview the output, and download the PDF. Supports multi-page content with automatic page breaks. All processing happens in your browser.
Converting HTML to PDF...
Turn any HTML code into a professional PDF document in three simple steps — no software installation required.
Paste your HTML code directly into the editor textarea, or click "Load HTML File" to import an .html file from your device. The code editor accepts any valid HTML including headings, paragraphs, tables, lists, images, and inline CSS styles. You can write a complete HTML document or just a fragment — the tool handles both.
Select your preferred page size — A4, US Letter, or US Legal. Choose between portrait and landscape orientation. Adjust the margin from 0 to 30 millimeters using the slider. Enable the live preview checkbox to see exactly how your HTML will render before converting, so you can fine-tune the layout.
Click "Convert to PDF" to generate your document. The tool renders your HTML at high resolution, automatically splits long content across multiple pages, and assembles everything into a clean PDF using pdf-lib. Once complete, click "Download PDF" to save the file to your device. Your code never leaves your browser.
A fast, private, and free way to turn HTML code into professional PDF documents — built for developers and everyone.
There is no premium tier, no usage cap, and no hidden paywall. Convert as many HTML files to PDF as you need without creating an account or paying anything. We believe essential developer tools should be accessible to everyone without restrictions.
Your HTML code never leaves your device. All rendering and PDF generation happens locally in your browser using html2canvas and pdf-lib. There is no server upload, no cloud processing, and no risk of your code or content being stored or accessed by anyone else.
Long HTML content is automatically split across multiple PDF pages at the correct dimensions. Whether your HTML produces a single page or dozens, the tool handles pagination seamlessly with consistent margins and formatting on every page.
Enable the live preview to see exactly how your HTML will render before converting. The preview updates in real time as you type, so you can adjust your code, styles, and layout until the output looks perfect — then convert with confidence.
Choose from three standard page sizes (A4, Letter, Legal), switch between portrait and landscape orientation, and fine-tune margins from 0 to 30 millimeters. These options give you full control over the final PDF layout to match your requirements.
ConvertKr runs entirely in your web browser, so it works on smartphones and tablets just as well as on desktop computers. There is nothing to install — if your device has a modern browser with JavaScript enabled, you can convert HTML to PDF on the go.
Everything you need to know about converting HTML code into professional PDF documents.
Why Convert HTML to PDF? HTML is the language of the web, but it is not always the best format for sharing, printing, or archiving content. PDFs preserve exact formatting across every device and operating system, making them ideal for invoices, reports, resumes, documentation, and any content that needs to look the same everywhere. Converting HTML to PDF lets you take advantage of HTML's flexible layout capabilities while producing a universally compatible output.
How the Conversion Works ConvertKr renders your HTML code in a hidden container that matches the exact pixel dimensions of your selected page size. The container uses system fonts and applies your chosen margin as padding. The tool then uses html2canvas to capture the rendered content as a high-resolution image at 2x scale for sharp text and graphics. If the content exceeds the height of a single page, it is sliced into page-sized chunks. Each chunk is embedded as a JPEG image in a PDF page created with pdf-lib, producing a clean multi-page document.
Tips for Best Results Use inline CSS styles or embedded style tags for the most reliable rendering. Avoid external stylesheets and JavaScript, as they are not loaded during conversion. Keep images to CORS-accessible URLs or use base64 data URIs. Use standard web fonts (system-ui, Arial, Georgia, monospace) for consistent rendering across devices. For tables and complex layouts, test with the live preview before converting. If your content is very long, the tool will automatically paginate it.
Supported HTML Features The tool supports all standard HTML elements: headings (h1-h6), paragraphs, lists (ordered and unordered), tables with borders and styling, blockquotes, horizontal rules, images, links (rendered visually but not clickable in PDF), spans with inline styles, divs with flexbox or grid layouts, and any valid CSS properties that the browser's rendering engine supports. You can include a full HTML document with doctype, head, and body tags, or simply paste a fragment.
Privacy and Security All HTML rendering and PDF generation happens entirely within your web browser. Your code is processed by html2canvas and pdf-lib — both client-side JavaScript libraries. No data is sent to any server at any point. The html2canvas library is loaded from a CDN on first use and cached by your browser. Your HTML code, rendered images, and generated PDF all exist only in your browser's memory and are cleared when you close the tab.
