The online stores that can keep up with offering the best user experience can only stand the competition in today’s market.
Now, store performance is all about the user experience. There’s no denying to the fact that Google considers the website loading speed as one of the ranking factors.
These statistics from Hosting Tribunal says it all:
- 1-second delay reduces page views by 11%.
- 1-second delay decreases customer satisfaction by 16%.
- 1-second delay eats away 7% of the coveted conversion rate.
- 1-3 seconds in loading time see a very low bounce rate probability – only 32%.
- Add 1 second more to that and the chance for users to bounce triples, reaching 90%.
- On an annual basis, the 1-second delay can lead to $2.5 million in missed revenue if your shop generates $100,000 per day.
Now that we know how precious just a second can be when it comes to website loading speed, one should not take any chance to speed up Magento 2 store
And one of the ways to do so is to enable merge CSS, javascript in Magento 2.
Unmerged CSS and javascript are one of the reasons for the low efficiency and high loading time of Magento 2 store.
Merging refers to the process of eliminating unnecessary or redundant data like line breaks without affecting how the browser processes the resource. It forbids the modification of the file after merging CSS and js.
The reduced number of requests to the server due to merge CSS and javascript will result in improved load time of the store.
And fortunately, our favourite CMS offers default feature to enable merge javascript, CSS from the admin panel!
Steps to Enable Merge CSS, Javascript in Magento 2:
1. Login to admin panel
2. Go to Stores > Settings > Configuration
3. From the left panel, expand the Advanced tab and select the Developer option.
4. Enable Merge CSS in Magento 2:
- Expand CSS Settings
- Set “Yes” in the Merge CSS Files dropdown.
5. Enable Javascript in Magento 2:
- Expand the JavaScript Settings section
- Set the “yes” option in the Merge JavaScript Files dropdown.
6. Save configuration
That’s it. Also if you made a CSS change into the files of your theme and if you are not able to see those changes in pub/static folder then regenerate CSS file in pub/static folder in Magento 2 and get a solution to your error.
You can also refer to the video tutorial to Enable Merge CSS, Javascript in Magento 2 from our Magento 2 video tutorial series:

Thank you.
