Canva by default exports websites as a presentation when the document size is not right. This is weird, but it is what it is.

Luckily, the fix needs two clicks, like the screenshot below. Then if you republish your design, it will work.

1. Click on the Resize button in the top left corner of the Canva editor.
2. Select Website from the dropdown menu. That’s it!

Ps. this is a Canva Pro feature. If you do not have Canva Pro, then there is another way. Please check the video below.

Enjoy the freedom!
