Submit an upload, image URL, or ASIN and get scores, findings, and fixes. Use PickFu's Amazon Main Image Grader, part of the free [PickFu Toolbox](https://www.pickfu.com/tools), to get an instant AI report card on your Amazon main image. The grader scores your image against six criteria, explains what it found, and recommends a fix for every criterion it flags. Use it before you invest in a split test or a live listing change. # What the grader checks The grader evaluates your main image against six criteria. Each criterion gets a score from 0 to 100, a finding, and the evidence in the image that supports it. Any criterion scoring below 70 is flagged and includes a recommended fix. * **Amazon's image rules:** Whether the image follows Amazon's main-image requirements and your category's conventions * **Legibility at thumbnail size:** Whether the image still reads clearly at the small size shown in search results * **Product clarity:** Whether shoppers can immediately tell what the product is * **Scale and quantity:** Whether shoppers can tell how big the product is and how many they get * **Image quality:** Whether the production quality looks credible and professional * **Standing out on the results page:** Whether the image drives clicks against neighboring listings The report also includes an overall score and a one-line headline summarizing the biggest opportunity. # How to grade your main image 1. **Enter your email and pass the check.** Before the grade runs, enter your email address, tick the consent checkbox, and complete the bot check. All three are required to start a run. 2. **Submit your image.** Provide the image in any of three ways: * Upload an image file * Paste a public https image URL * Enter an Amazon ASIN or product URL, and PickFu fetches the listing's current main image for you 3. **Verify your email.** While the grade runs, PickFu emails you a 6-digit verification code. The code expires after 15 minutes, and you get 5 attempts before you need to request a new one. Until you verify, the preview shows only how many criteria passed and how many were flagged. 4. **Open your full report.** After you verify, the full report unlocks with every score, finding, evidence, and fix. PickFu also emails you a link back to the report, so you can return to it later, and you can copy the link or export the report as Markdown. # How long reports last Reports expire 60 days after the run. After that, the report link stops working and PickFu deletes the report and any image you uploaded. Export the report or act on its fixes before the 60 days are up. # FAQs **Is the grader free?** Yes. You only need to provide and verify an email address to unlock the full report. **What can I submit?** An image file upload, a publicly reachable https image URL, or an Amazon ASIN or product URL. If you submit an ASIN, PickFu grades the listing's current main image. **Why is my report showing only pass and flag counts?** The full report is locked until you verify your email. Enter the 6-digit code PickFu emailed you. If the code expired, request a new one. **What should I do after fixing my image?** Validate the new image with real shoppers. Run a [head-to-head PickFu poll](/help/how-to-optimize-your-amazon-main-image) comparing the old and new versions before you change the live listing. *** Related Articles * [How to Optimize Your Amazon Main Image](/help/how-to-optimize-your-amazon-main-image) * [Improving your Amazon main image CTR with PickFu](/help/improving-your-amazon-main-image-ctr-with-pickfu-getting-started-faqs) * [Amazon listing mockup generator](/help/amazon-listing-mockup-generator) * [How do I test Image Sets with PickFu?](/help/how-do-i-test-image-sets-with-pickfu) ## Related topics - [How to Optimize Your Amazon Main Image](/help/how-to-optimize-your-amazon-main-image.md) - [PickFu Help Center](/help.md) - [Amazon main image optimization](/docs/playbooks/amazon-main-image.md) - [Improving Amazon main image CTR with PickFu](/help/improving-your-amazon-main-image-ctr-with-pickfu-getting-started-faqs.md) - [Surveying best practices](/help/polling-best-practices.md) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
