Amazon Product Detail Page will not show HTML formatting
Don’t worry! This change will be implemented after June 8, 2021. In the meanwhile we strongly suggest you to start revise all your products descriptions and replace HTML formatting parts with those supported. Don’t use HTML, DHTML, JavaScript, or other types of code in your product detail pages. As a special case, you can use line breaks ( ) as necessary in the description.
It would be a pity, if customers can not read all the informations about your products, therefore decide to go for your competitors’ products, because of technical issue.
It is very important to take this Amazon Update very seriously, because this can compromise your Listings Optimization and, as a consequence, your sales. In fact, one of the best way to increase sales is to optimize and write clear, natural and informative descriptions. Moreover, by giving accurate descriptions of your products, a customer is less likely to give you a bad review for being misleading.

FAQ: Amazon Product Detail Page HTML formatting change
Why did Amazon stop supporting HTML formatting on product detail pages?
Amazon wanted product detail pages to display correctly for every customer, including those browsing on devices that can’t render HTML. Removing HTML, DHTML, and JavaScript support ensures the page content is visible and consistent regardless of the device being used.
When did this change take effect?
The change was implemented after June 8, 2021. Sellers were advised to revise their product descriptions ahead of that date and replace any HTML formatting with supported alternatives.
What can sellers use instead of HTML in their descriptions?
Line breaks are still supported and can be used as needed within the description. Beyond that, Amazon requires plain text — no HTML, DHTML, JavaScript, or other code — in product detail pages.
Why does this update matter for sales and reviews?
If customers can’t read all the information about a product because of leftover HTML formatting issues, they’re more likely to turn to a competitor’s listing instead. Clear, natural, and informative descriptions also reduce the chance of a customer leaving a bad review for feeling misled by inaccurate or garbled information.
How can sellers update large catalogs quickly after this change?
Manually revising descriptions across hundreds or thousands of products is time-consuming, which is why Epinium built software that connects to a seller’s Seller Central profile to write, upload, optimize, and modify descriptions directly — including mass changes across an entire catalog, with HTML formatting automatically replaced according to Amazon’s rules.
