What is a WordPress Conversion Service?
A WordPress conversion service turns a finished design (Figma, PSD, XD, Sketch, or static HTML) into a fully functional, hand-coded WordPress theme. The output is a custom theme (not a customised template) with editor-friendly content fields, responsive layouts, and the speed and SEO foundations a real business site needs.
At MarkupFox, every WordPress conversion is hand-coded by senior developers against the official WordPress Coding Standards. That means proper hooks and filters, escape and sanitise discipline, Advanced Custom Fields (ACF) for editorial control, and either native Gutenberg blocks or a classic theme (whichever fits your content workflow). No Elementor. No Divi. No bundled-plugin bloat. Just clean PHP/JS/CSS and a Lighthouse score above 90.
HTML to WordPress Conversion
Already have a static HTML/CSS site and want it on WordPress? Our HTML to WordPress conversion service rebuilds your site as a custom WordPress theme, preserving the exact design, markup quality, and performance characteristics of the original while giving your team a CMS to manage content, blogs, and landing pages on their own. Need broader scope than a fixed conversion (custom plugins, FSE block themes, headless WordPress)? See our WordPress development services retainer.
This is the right path when your existing static site is well-built but needs editorial workflow, when an agency delivered HTML and you need it converted to WordPress for self-management, or when you're migrating from a flat-file site to a real CMS without losing your design fidelity. If you only need the static HTML build itself (no CMS), see our design to HTML conversion service; the markup we produce there is the same foundation we wrap into a WordPress theme here. If your project needs structured content, fine-grained editorial roles, or multi-site at the core layer, our Drupal development services are usually the better fit instead. And if the front-end is a true single-page application rather than a CMS-driven site, see our design to React & Angular conversion service. Selling products? Our design to Shopify conversion service covers OS 2.0 themes and Hydrogen headless storefronts. And if you're building marketing campaigns or transactional flows on top of the new site, our email development services ship ESP-ready, dark-mode-tested templates. Considering Joomla instead for multilingual-first or membership sites? See our Joomla development services. For visual-first marketing builds where the editor team values Webflow's Designer, see our Webflow development services. If your source is specifically a Figma file and you only need the static markup (no CMS), see our Figma to HTML conversion services.
What an HTML to WordPress conversion includes
- Theme architecture: header.php, footer.php, page.php, single.php, archive.php, and template parts mapped from your HTML structure
- ACF field integration: every editable region in your HTML becomes a custom field, repeater, or flexible content block
- Menu & navigation: wp_nav_menu() with mega-menu, dropdown, and mobile drawer support
- Custom post types: for blog, portfolio, services, team, testimonials, products, etc.
- Asset pipeline: wp_enqueue_script() and wp_enqueue_style() with versioning, no inline styles, no broken cache
- Form handling: Contact Form 7, WPForms, or custom REST endpoints
- SEO continuity: Yoast/Rank Math integration plus 1:1 redirect mapping from old URLs to preserve rankings
- Performance preservation: the WordPress version matches or beats the static site's Lighthouse score
Sketch to WordPress Conversion
Designed in Sketch? We've been converting Sketch files to WordPress themes since the early Bohemian Coding days. Send us your .sketch file and we ship a custom hand-coded WordPress theme with symbols, text styles, and layer groups all preserved as a structured component system in your theme.
Sketch remains popular with macOS-first design teams and legacy design systems, especially in agencies and product teams that adopted it pre-2020. Our Sketch to WordPress conversion process is identical in quality to our Figma path: same senior developers, same WordPress coding standards, same 90+ Lighthouse target. The one practical difference: we work directly from your .sketch source rather than asking you to re-export to PNG or Figma first. If you only need the static markup (no WordPress backend), see our Sketch to code conversion services.
Our Sketch to WordPress workflow
- Source review: we audit your
.sketch file for Symbols, Text Styles, Layer Styles, and Artboards. Shared libraries are mapped to reusable theme components. - HTML/CSS extraction: Sketch artboards are hand-coded into semantic HTML5 + CSS3, retaining exact spacing, typography, and responsive breakpoints from your design.
- WordPress integration: the static markup becomes a custom WordPress theme: template hierarchy, ACF flexible content, custom post types, and Gutenberg block patterns where they fit.
- Sketch Symbols to ACF blocks: repeated UI patterns from Sketch Symbols become reusable ACF Flexible Content blocks or Gutenberg block patterns. Editors get the same modularity you designed for.
- QA & delivery: cross-browser tested, Lighthouse-validated, and shipped with admin documentation.
Typical turnaround: 5–7 business days for a single-page Sketch to WordPress conversion, 10–15 business days for a full site. Pricing matches our standard packages; your design source format doesn't change the cost.
