Frequently Asked Questions
Simply paste your HTML code into the editor on the left. Your content renders in real-time in the preview panel. Click "Print to PDF" to use your browser's native print dialog (select "Save as PDF" as the destination), or click "Download PDF" to generate and download a PDF file directly without a print dialog.
Yes! Use the "Selector" input in the settings bar. Enter a CSS selector (like
#invoice-table or .print-area) to extract and print only that element. This is perfect for printing specific sections of a larger page—one of the standout features our users love compared to basic HTML-to-PDF converters.We support A4, US Letter, Legal, A3, and A5 paper sizes in both portrait and landscape orientations.

Our tool adds several advantages: (1) a live preview so you see exactly what prints, (2) the ability to inject custom CSS including
@media print styles, (3) element-specific printing via CSS selectors, (4) template presets to get started quickly, and (5) a direct "Download PDF" option that bypasses the print dialog entirely using html2canvas + jsPDF.Yes, images and external CSS are supported in the live preview and when using the Print to PDF option. For the Download PDF feature, images from external URLs may require CORS headers to be rendered correctly. We recommend using base64-encoded images or same-origin resources for the best Download PDF experience.
Absolutely! Add
@import rules or <link> tags in your HTML or CSS editor to load Google Fonts or other web fonts. These will render in the preview and carry through to the printed PDF. For the Download PDF option, standard web fonts work best; highly decorative fonts may fall back to system defaults in the canvas-rendered output.Yes, completely free with no limitations, no watermarks, and no sign-up required.
