Why Convert HTML to PDF?
Freeze web content into a fixed-layout document that looks identical everywhere — whether printed, emailed, or archived for years.
Print-Perfect Output
Web pages reflow on different screens. PDF freezes your layout at a specific size — A4, Letter, or custom — with precise margins, page breaks, and print-ready resolution (300 DPI).
Content Preservation
Web pages change or disappear. A PDF snapshot preserves the content exactly as rendered — fonts, images, layouts — immune to future website changes, server outages, or link rot.
Universal Sharing
Not everyone has a browser or internet access. PDFs can be emailed, printed, or viewed offline on any device. No web server needed, no rendering differences between browsers.
Legal & Compliance
Courts and regulators require fixed-format documents. Convert web-based contracts, terms of service, or compliance reports to PDF for legal admissibility and audit trails.
Full CSS3 Rendering
Our renderer processes modern CSS — Flexbox, Grid, custom fonts, gradients, shadows, and media queries. What you see in the browser is what you get in the PDF.
Configurable Output
Set page size, margins, orientation, headers/footers, and viewport width. Control which CSS breakpoint renders by specifying the viewport — ideal for capturing desktop or mobile layouts.
How to Convert HTML to PDF
Our converter uses a headless browser engine to render your HTML exactly as a browser would, then paginates the output into a high-quality PDF document.
Upload HTML
Drag and drop your .html file (with linked CSS and images). We also support ZIP archives containing HTML with assets.
Browser Rendering
A headless Chromium engine renders your HTML — executing CSS3, JavaScript, and loading web fonts. The page renders exactly as it would in Chrome.
PDF Pagination
The rendered page is sliced into your chosen page size (A4, Letter, etc.) with configurable margins. CSS page-break rules are respected for clean pagination.
Download PDF
Download your print-ready PDF with embedded fonts, clickable links, and vector text. Open in Adobe Acrobat, Preview, Chrome, or any PDF reader.
Common Use Cases
HTML to PDF conversion is essential whenever web content needs to leave the browser.
Invoice & Report Generation
SaaS applications generate invoices, receipts, and reports as HTML templates, then convert to PDF for download or email. FastlyConvert handles the rendering so your backend doesn't need a PDF library.
Web Page Archiving
Preserve web articles, research pages, and documentation as PDFs before they change or go offline. Journalists, researchers, and legal teams archive web evidence as timestamped PDFs.
Contract & Proposal PDFs
Design contracts and proposals as styled HTML pages, then convert to PDF for client delivery. Maintain your brand's web design aesthetic while producing formal, signable documents.
Course Material Distribution
Convert web-based course content, lecture notes, and interactive tutorials into printable PDFs. Students can study offline, annotate with highlighters, and organize materials by topic.
Frequently Asked Questions
Technical questions about HTML to PDF rendering and output quality.
Does the converter render CSS3 and JavaScript?
expand_more
Yes. Our headless Chromium engine processes CSS3 in full — including Flexbox, Grid, custom properties (variables), gradients, shadows, and @font-face web fonts. JavaScript is executed before rendering, so dynamic content generated by JS frameworks (React, Vue, etc.) is captured in the PDF output.
Can I set custom page size, margins, and orientation?
expand_more
Yes. Choose from standard page sizes (A4, US Letter, Legal, A3) or specify custom dimensions in millimeters. Set top/bottom/left/right margins independently, choose portrait or landscape orientation, and optionally add headers and footers with page numbers, dates, or custom text.
How does it handle responsive HTML layouts?
expand_more
Responsive pages are rendered at a configurable viewport width (default 1280px). CSS media queries fire based on this width, so you control which breakpoint gets captured. Set viewport to 375px to capture a mobile layout, or 1920px for a full desktop view. The @media print query is also respected.
Are hyperlinks and bookmarks preserved?
expand_more
Yes. HTML anchor tags (<a href="...">) become clickable links in the PDF. Internal page anchors become PDF bookmarks in the navigation panel. The table of contents structure from your HTML heading hierarchy (h1–h6) can be automatically extracted as PDF bookmarks.
Can I control page breaks in the PDF?
expand_more
Yes. Use CSS page-break properties: page-break-before: always to force a new page, page-break-inside: avoid to prevent elements from splitting across pages. The @page CSS rule lets you set per-page margins and sizes. These are standard CSS Print properties supported by our renderer.
Is my HTML file secure during conversion?
expand_more
Yes. All uploads are encrypted via HTTPS/TLS and automatically deleted within 24 hours. HTML files are rendered in isolated sandboxed containers — no network access during rendering, no human access, no content storage beyond the conversion session.
How HTML to PDF Rendering Works
Converting HTML to PDF is fundamentally a rendering problem. A web browser must parse HTML, apply CSS styles, execute JavaScript, load external resources (fonts, images), compute the layout, and then "print" the result to a fixed-size page instead of a scrollable viewport. This is why quality varies dramatically between converters — simple regex-based tools produce terrible output, while browser-based renderers like Chromium produce pixel-perfect results.
FastlyConvert uses a headless Chromium instance — the same rendering engine that powers Google Chrome. Your HTML is loaded in a real browser environment with full CSS3 support, JavaScript execution, and web font loading. Once the page is fully rendered (including async JS), we trigger the browser's native PDF generation, which produces vector text (searchable and selectable), embedded fonts, and clickable hyperlinks.
The key challenge in HTML-to-PDF conversion is pagination. Web pages scroll infinitely; PDFs have fixed pages. Our renderer respects CSS page-break properties, avoids orphan lines (single lines left at the top/bottom of a page), and intelligently splits tables across pages when needed. For developers: you can fine-tune output with @media print CSS rules, which our renderer processes just like Chrome's print dialog.
