100% In-browser confidentiality

Your customer invoices, medical forms, internal metrics, and custom HTML scripts are processed completely inside your device RAM without uploading to external servers.

Multi-page auto-pagination

Continuous web content is intelligently sliced across standard ISO A4 or US Letter pages, preventing cut-off text, broken tables, or awkward vertical overflows.

Full CSS3 & Web fonts support

Render modern web designs with Flexbox, CSS Grid, custom border styles, gradients, Google Fonts, and embedded SVG vector graphics with pixel precision.

Ready-to-use business presets

Includes verified Indian GST tax invoices, university certificates, corporate status reports, and modern resumes ready for instant editing and PDF export.

Configurable margins & paper size

Easily switch between A4, US Letter, US Legal, and A3 formats with customizable millimeter margin presets and portrait or landscape orientation.

Ultra crisp high-DPI rendering

Choose between 2x and 3x retina scaling to ensure razor-sharp typography and crisp image details suitable for professional commercial printing.

Built to the PDF specification (ISO 32000) and W3C HTML5 / CSS3 — conversion runs entirely in your browser.

Frequently Asked Questions

How do I convert HTML code or .html files to PDF?

You can either paste your custom HTML and CSS code directly into the editor pane, click on any of our built-in business presets (GST invoice, certificate, report, resume), or upload an existing .html file from your computer. Once previewed, select your page setup and click "Convert to PDF & Download" to compile your document.

Does the converter preserve CSS styles, Google Fonts, and images?

Yes! Modern styling features including Flexbox, CSS Grid layouts, web fonts (like Google Fonts Inter and Roboto), borders, gradients, inline SVGs, and base64 images render with high visual fidelity directly in your browser.

How does multi-page auto-pagination work for tall documents?

Unlike basic tools that shrink entire web pages into a single squished sheet, Vytra's smart pagination engine measures vertical height and slices tall HTML layouts across consecutive A4 or US Letter pages with clean margins and natural document flow.

Is my HTML code or client invoice data uploaded to any remote server?

No. All parsing, canvas rasterization, and PDF synthesis occur 100% inside your web browser. Neither your HTML source code, proprietary business figures, nor generated PDF files ever leave your machine.

What is the recommended page size and margin setting for printing?

For standard business invoices, certificates, and academic reports in India, the UK, and Europe, ISO A4 Portrait with Normal (12 mm) margins is standard. In North America, US Letter format is recommended.

Can I convert HTML to PDF on mobile devices (Android / iOS)?

Yes, Vytra is fully mobile-responsive. You can edit code or choose templates and generate PDFs directly on iPhone Safari, Android Chrome, tablets, and desktop browsers without installing apps.
