How a browser-based converter differs from other tools
Most conversion methods start from source files: HTML exports, a Webflow project, a Git repo. A Chrome extension in this category instead starts from what's rendered in the browser tab — the final DOM, computed CSS and any JavaScript-driven layout — which means it can work even on sites where you have no access to the underlying code at all.
This matters for competitor research pages, sites with lost source files, or designs delivered as a live preview link rather than a code handoff.
How Themify's extension processes a page
Themify installs as a Chrome or Firefox extension. You navigate to the page you want to convert, trigger the capture, and it reads the rendered page in place — including CSS and JavaScript animations — then assembles it into a classic WordPress theme with style.css, index.php, header.php, footer.php, functions.php and the site's assets, downloadable as a .zip.
The processing happens locally in your browser rather than uploading your source code to an external server, which is a meaningful distinction if you're converting a page you don't have explicit rights to redistribute freely elsewhere.
What to check before using any browser extension for this
Confirm what happens to the captured data — whether processing is local or sent to a server, and whether the extension keeps a copy after the conversion finishes. Check what output format you get: a proper theme .zip with the standard WordPress files is far more useful than raw HTML you'd still need to convert manually.
Also check installed extension permissions in Chrome's extension settings; a conversion tool reasonably needs access to the active tab's content, but should not be requesting broad, unrelated permissions.
- Local vs server-side processing of your captured page
- Whether output is a real installable theme or just raw HTML
- Extension permissions requested in Chrome
- Trial availability before paying
- Refund policy if the output doesn't fit your project
Installing and using the extension end to end
Add the extension from the Chrome Web Store (or Firefox Add-ons), open the target website in a new tab, and use the extension's toolbar icon to start a capture. Once processing finishes, you download a .zip file that's ready to upload.
In wp-admin, go to Appearance → Themes → Add New → Upload Theme, select the downloaded .zip and click Install Now, then Activate to switch the site to the new theme.
- Install the extension from the browser's official store
- Open the website you want to convert in a tab
- Trigger the capture from the extension icon
- Download the generated theme .zip
- Upload it via Appearance → Themes → Add New → Upload Theme
- Activate and test on staging before going live
Pricing to expect from this category of tool
Themify offers one free trial conversion, then paid plans: Basic at $9/month for 10 conversions, Pro at $29/month for 20 conversions, and Agency at $99/month for unlimited conversions. Yearly billing saves up to 30 percent, and there's a 14-day money-back guarantee if the output doesn't work for your project.
For a single site conversion, the free trial is enough to evaluate output quality before you decide whether a paid tier makes sense.
Where a browser extension conversion has limits
It captures what's visually rendered, not server-side logic, so login systems, checkout flows or database-backed features on the original site won't be recreated automatically — those still need real development work inside the new WordPress theme.
It also won't retroactively fix accessibility or SEO issues baked into the original markup; it preserves what's there, so a page with poor heading structure will still have poor heading structure after conversion unless you fix it in the resulting theme files.
Frequently asked questions
- Is it safe to use a Chrome extension to convert a website to WordPress?
- It depends on the extension's permissions and whether it processes your captured page locally or on a remote server. Themify processes captures locally in the browser without uploading source code.
- Does the Chrome extension need access to my WordPress admin?
- No, capturing the page and generating the theme happens independently of WordPress. You separately upload the resulting .zip file through Appearance → Themes once it's ready.
- Can a Chrome extension convert a site with a login-protected area?
- It can capture whatever is visibly rendered on a page you're viewing, but it can't recreate server-side authentication logic — that portion still needs custom development in WordPress.
- How much does a Chrome extension conversion tool typically cost?
- Themify offers a free trial conversion, then plans starting at $9/month for 10 conversions, scaling up to $99/month for unlimited conversions on the Agency plan.
- What file do I get after using the extension, and what do I do with it?
- You get a downloadable .zip containing a standard WordPress theme structure, which you upload via Appearance → Themes → Add New → Upload Theme in wp-admin.
