How to Bulk Convert Classic Blocks to Gutenberg in WordPress

If you’re updating to the newest version of WordPress, older content may appear in the Classic block within the new editor. And if you have a large number of posts, converting these Classic blocks to Gutenberg blocks one by one can be time-consuming.

Luckily, there’s an easier way to bulk convert them.

At WPBeginner, we originally used the Classic Editor but switched to Gutenberg when it launched. This meant converting older posts from Classic blocks to Gutenberg, giving us hands-on experience with the process.🔄

Over time, we’ve mastered this transition, making it smooth and efficient.⚡

In this article, we will show how to easily bulk convert classic blocks into Gutenberg blocks on your WordPress site.

Why Convert Classic Blocks to Individual Gutenberg Blocks?

Converting Classic blocks into individual Gutenberg blocks gives you more control and flexibility over your content.

If your WordPress blog has older posts created with the Classic Editor, they will appear inside a Classic block in the block editor.

By converting them, each paragraph, heading, and image becomes its own editable block.

This allows you to easily edit and customize your posts using the block editor’s features.

You can adjust settings in the sidebar for each block, and take advantage of layouts and design options that weren’t available in the Classic Editor—like columns, image galleries, buttons, and more.

Overall, converting to Gutenberg blocks makes your content easier to manage and lets you create more engaging, modern layouts for your readers.

That being said, let’s see how to easily bulk-convert classic blocks to Gutenberg in WordPress. We will cover 2 methods, and you can use the quick links below to jump to the one you want to use:

Method 1: Convert Classic Block to Gutenberg Using Default Settings

If you want to convert a single post or page from the Classic block into individual blocks, then this method is for you.

First, you need to edit the post and page where you want to convert the blocks. You can do this by heading to the Posts » All Posts page in your WordPress dashboard. Then, click the ‘Edit’ link under the post you wish to convert.

This will open your post in the Gutenberg editor. From here, simply click on the ‘Convert to blocks’ button in the toolbar at the top of the Classic block.

The Classic block will now be converted into individual Gutenberg blocks.

You can now also access all the block settings for individual blocks from the right column. If you cannot see this panel, then click on the gear icon at the top right of the editor.

Once you are done, don’t forget to click the ‘Update’ button to save your changes.

Method 2: Bulk Convert Classic Block into Gutenberg Blocks

If you want to easily convert the Classic block into Gutenberg blocks for all the old posts and pages immediately, then this method is for you.

First, you need to install and activate the Convert to Blocks plugin. For more instructions, please see our step-by-step guide on how to install a WordPress plugin.

The plugin streamlines the conversion process. Once activated, it automatically converts any post or page from the Classic block into individual blocks the moment you open it in the editor.

This saves you from having to manually click the ‘Convert to blocks’ button for each post, making it a great time-effective tool.

Remember that the bulk conversion will not affect the layout of your posts on the front end, so the posts will look the same on your WordPress website.

This is how the same post looked on our demo site after converting it from Classic to individual blocks.

After the bulk conversion is complete, the plugin has done its job. You can then safely deactivate and delete the Convert to Blocks plugin to keep your site tidy.

Bonus Tips and Tricks to Use the Block Editor

Now that you are using the block editor on your WordPress site, you can access some powerful features unavailable in the classic editor. Here are some key blocks and functionalities to explore:

• Group and Column Blocks: Organize multiple elements like images, headings, and paragraphs into flexible, multi-column layouts. This allows for visually appealing and structured page designs.
• Embed Block: Seamlessly insert content from popular third-party sources such as YouTube, Discord, Twitter, Facebook, and more directly into your posts.
• Cover Block: Integrate text and media content (images or videos) within a single block to create striking section headers, banners, or full-width background sections.
• Table Block: Easily create structured data displays without needing to write custom HTML, offering basic styling and column/row management.
• Button Block: Add customizable call-to-action buttons with options for color, style, and link.
• Nested blocks: Place blocks inside other blocks (e.g., buttons within a column block or paragraphs within a group block) for advanced design possibilities.
• Block Patterns: Save frequently used block configurations or complex layouts as reusable blocks or patterns, allowing you to quickly insert them across your site.

Frequently Asked Questions About Converting Classic Blocks to Gutenberg

Here are some questions that our readers frequently ask about converting the classic blocks to Gutenberg in WordPress:

Will converting blocks break my site?

No, in most cases, converting Classic blocks to individual Gutenberg blocks will not break your site’s appearance.

The main change happens in the back-end editor, giving you more control over individual elements. We always recommend spot-checking a few important posts or pages after the conversion just to be safe.

Can I undo the conversion?

The bulk conversion using the plugin is a permanent change and cannot be easily undone. Once the classic content is converted into blocks, there isn’t a reversal button.

This is why creating a complete WordPress backup before you begin is a critical step. If you run into any issues, you can restore your site from that backup.

Is the ‘Convert to Blocks’ plugin free?

Yes, the ‘Convert to Blocks’ plugin we mentioned in the second method is completely free. You can find and install it directly from the official WordPress plugin directory.
