Book Description HTML Formatter

Amazon KDP descriptions allow only a small set of HTML tags. Write with simple markup below and copy clean, KDP-safe HTML — with a live character count against the 4,000-character limit (HTML included).

Markup: **bold**, *italic*, a line starting with # becomes a heading, lines starting with - become a bullet list, blank lines separate paragraphs.

KDP-safe HTML — 0/4000 characters

Frequently Asked Questions

                

                    What HTML tags does KDP allow in book descriptions?
                    
A small whitelist: <b>, <i>, <u>, <br>, <p>, <ul>/<ol> with <li>, and headings h4-h6. Tags like <img>, <a>, <div>, <span> and inline styles are stripped or rejected.

                

                

                    How long can an Amazon book description be?
                    
4,000 characters, and the HTML markup counts toward the limit. The first ~3 lines show before the "Read more" fold on mobile, so front-load your hook.

                

                

                    Why does my KDP description formatting look wrong?
                    
Usually smart quotes or pasted invisible characters from Word, or an unclosed tag. Generate clean HTML here, paste it into a plain-text editor first if in doubt, and avoid nested formatting.
