Use this interactive demo to learn how to embed an HTML file directly into a WordPress page.

Quick summary

Uploading an HTML file to WordPress requires using the Block Editor to insert a Custom HTML block or a File block, then pasting or uploading your code directly to the page. This step-by-step process lets WordPress users add custom HTML content without needing a plugin or theme code changes.


Steps

  1. Navigate to your Admin Dashboard and click Pages in the left sidebar.
  2. Choose an existing page and click on it to open the editor.
  3. Click the Block Inserter button to open the block search panel.
  4. In the search bar, search for the HTML block option.
  5. Click Custom HTML and add it to your page.
  6. Alternatively, search for the File block and add it to your site instead.
  7. Use the Custom HTML block to paste your HTML code manually into the code block.
  8. In the module that appears, select the upload option to upload your file, or add it to your Media Library.
  9. Click Save to apply your changes.
  10. Your HTML file has been successfully uploaded and embedded in WordPress.

📌 Why this matters

Embedding custom HTML in WordPress unlocks advanced functionality — from interactive widgets to third-party integrations — without requiring a developer or custom plugin. WordPress's built-in Custom HTML block and File upload feature make it straightforward to add raw HTML code directly to any page or post. Understanding this workflow helps site owners maintain full control over their content and layout while staying within the native WordPress editor. This is an essential skill for anyone managing a WordPress site who wants to extend functionality beyond standard blocks.
