Short answer

The HORAiZON ONE Amazon description editor is a free browser tool that turns text you format in a visual editor, or paste as HTML, into an Amazon product description with paragraphs (), bold (), bullet lists (<ul>, <li>) and line breaks ( ), the same tags HORAiZON ONE publishes to Amazon, and checks it against the 2,000-character limit and Amazon's content rules.

A line breaks only mode covers Amazon's stricter written rule. The editor needs no account and does not store the text.

What HTML Amazon renders in the product description

Amazon's product detail page rules prohibit HTML, JavaScript and other code in detail pages and name one exception: "As a special case, you can use line breaks" in the description. In practice Amazon still renders a small set of formatting tags in the product description: , , <ul> with <li>, and . HORAiZON ONE publishes descriptions with exactly these tags, and the editor produces the same set.

How the editor handles HTML tags in Amazon product descriptions
Tag	Editor output	Notes
<p>	Kept	One paragraph. An empty line in plain text starts a new one
<b>, <strong>	Kept as <b>	Bold. text in plain text becomes bold too
<ul>, <li>	Kept	Bullet list. Lines starting with - or • become list items
<ol>	Converted to <ul>	Numbered lists become bullet lists
<br> or <br />	Kept	New line inside a paragraph. You choose the spelling
<h1> to <h6>	Converted	Becomes a bold paragraph
<i>, <em>, <u>, <span>, <font>, <div>	Removed, text kept	Divs become paragraphs
<a href>, URLs	Link removed, flagged	Links and web addresses are not allowed anywhere in the listing
style, class and other attributes	Removed	Amazon ignores them and they cost characters

Because Amazon's written rule only names line breaks, the editor also has a line breaks only mode. It turns paragraphs into empty lines and list items into lines starting with • or –. Use it if formatting gets stripped in your category or a flat-file template expects plain text.

The 2,000-character limit counts the tags

The product description field holds 2,000 characters including spaces, and HTML tags count toward it. A costs 4 characters, a paragraph () 7 and a list item (<li></li>) 9. A description with 10 paragraphs and an 8-item list spends about 150 characters on tags. A description over the limit is rejected; flat-file uploads report error 90117. The editor shows what Amazon counts, what a shopper reads and how much goes to tags. If a description is just over the limit, line breaks only mode saves characters.

A description structure that reads well on mobile

Opening paragraph: the main benefit in one sentence, the way a shopper would say it. Bold it if you like.
Two or three short paragraphs of two to three sentences each.
Hard facts as a bullet list: size, weight, material, compatibility.
One line for what is in the box, one for care or use instructions.
Bold for a few key words only, never whole paragraphs.
No prices, offers, shipping promises, guarantees, links or contact details.

Brand owners can replace the plain description with A+ Content, which allows images, comparison charts and, with Premium A+, video. For the keywords that matter for ranking, the title, bullet points and backend search terms carry more weight than the description.

How this editor compares

Clean-up, not only formatting buttons

Editors such as the SellerApp product description editor and the AMZ Data Studio HTML converter build formatting with buttons. The HORAiZON ONE editor also works the other way round: it takes HTML pasted from a shop system, Word or an old listing and removes what Amazon does not use, such as style and class attributes, spans, fonts, headings and links, keeping only , , lists and .

Rule checks, not just formatting

Besides formatting, the editor flags what gets descriptions edited or removed: links, email addresses, phone numbers, promotional wording such as "free shipping" or "best seller", words in all caps and emojis. It also shows how many of the 2,000 characters the tags use.

Writing the description itself

The editor formats text you already have and uses the same tag set as HORAiZON ONE. HORAiZON ONE's AI product copy writes the description together with the title, bullet points and backend keywords from 5.4 million real Amazon search terms and publishes it through the SP-API after approval.
