How the Bestseller Comparison Works
Readers first see your book as a small thumbnail next to the bestsellers in your genre. This free tool shows you that view before you publish, so you can judge your cover the way readers will.
- Choose your cover – a JPEG, PNG or WebP file up to 10 MB. Your cover stays in your browser.
- Choose your genre – only fully reviewed Top 100 bestseller charts are included.
- Create the comparison – you get two images to download: your cover placed among the Top 20 and among the Top 50 bestsellers.
Look at whether your cover stands out, whether the title is readable at thumbnail size, and whether it clearly signals its genre next to the books your readers already buy.
