Migration · HTML → WordPress

HTML to WordPress Static , without losing what made it fast.

A static HTML site has real virtues — it is fast and nothing breaks. Its cost is that every edit needs a developer. Converting to WordPress makes the site editable without surrendering the virtues: your existing design becomes a proper theme, your URLs stay put, and the performance is preserved deliberately rather than lost to a page builder.

  • Your existing design converted into a clean WordPress theme
  • URLs preserved exactly — often no redirects needed at all
  • Static-site speed kept: lean theme, no builder bloat

Why switch

Why people leave HTML.

Every edit is a developer task

Changing a phone number should not require a code deploy. WordPress hands routine edits to your team.

Content cannot scale

A blog, a careers page, a news section — on static HTML each becomes hand-made pages. A CMS makes them workflows.

No structure to build on

Forms, search, users, ecommerce — each is a bolt-on service on static hosting. WordPress provides the platform.

Knowledge lock-in

The site only changes through whoever knows the codebase. A CMS removes the single point of failure.

What moves

What comes with you, and how.

Scope your migration ↗︎
  1. Design → converted into a WordPress theme: your HTML/CSS becomes templates and patterns
  2. Pages → recreated as editable WordPress pages with the block editor
  3. Repeating sections → turned into reusable block patterns your team can use on new pages
  4. URLs → matched exactly where possible (about.html → /about/ handled with slugs and redirects)
  5. Forms → rebuilt on a form plugin with spam protection and reliable email delivery
  6. Assets → images and files moved into the media library, optimised on the way in

The HTML specifics

The gotchas we plan for.

Every platform has traps that generic migration checklists miss. These are the HTML-specific ones — the difference between a clean move and a rescue job.

Conversion is not copy-paste

Wrapping your HTML in a theme technically works and creates an unmaintainable mess. Proper conversion means templates, patterns and theme.json — so the site is genuinely editable, not just hosted differently.

Keep the speed on purpose

Static sites are fast because they do nothing. The WordPress build must protect that: a lean theme, no page-builder overhead, caching that serves pages as fast as the static files did.

.html URLs need a decision

Old links to /about.html should keep working. Either preserved via permalink settings or 301-redirected to clean slugs — decided site-wide, not left to chance.

Hidden dynamic bits

That one PHP contact script or embedded third-party widget needs a proper WordPress equivalent — inventory them before the build, not during launch week.

Editing needs guardrails

The point is editability — but unlimited editability decays the design. Locked patterns and a defined palette keep the site looking like your site a year later.

Process

How the move runs.

Our full process ↗︎

Every migration is a parallel build: your HTML site keeps running while the new WordPress site is built and verified beside it. The switch is a planned window, not a leap.

  1. Audit and inventory. Content, URLs, rankings, integrations — everything that must survive gets listed before anything moves.
  2. Parallel build. The WordPress site is built and the data migrated on staging, while the live site trades on untouched.
  3. Verification. Content counts, redirect map, metadata parity, forms — checked against the inventory.
  4. Cutover. DNS switches in a low-traffic window; the old site stays reachable to us until everything is confirmed.
  5. Aftercare. We watch Search Console, 404s and the numbers for the following weeks and fix what the real world surfaces.

Questions

HTML migration questions.

If your situation isn't covered here, send us the details and we'll reply with a straight answer.

Ask your question ↗︎
Will the site look exactly the same after conversion?

Yes — the design is yours already. We convert your HTML and CSS into a WordPress theme that renders the same design, then structure it into editable patterns. Visitors see the same site; your team sees an editor where the code used to be.

Will WordPress make the site slower?

Not the way we build it. The speed of a static site is protected deliberately: a lean hand-built theme, no page-builder bloat, and full-page caching that serves HTML as fast as the static files did. Converted sites routinely keep their performance scores.

What happens to our existing URLs?

They survive. Clean paths carry over exactly; .html-style URLs are either preserved or 301-redirected to clean slugs as a site-wide decision. Existing links and rankings keep working either way.

Can parts of the site stay hand-coded?

Yes. A hybrid is common — templated, rarely-changing sections stay as fixed theme templates, while pages your team edits live in the block editor. We draw that line together based on who actually changes what.
