Visualize Your Book in Every Reader Scenario
Don't publish blindly. Our generator provides instant, context-aware previews to ensure your cover wins clicks in search results and looks crisp on E-ink devices.
Search Thumbnail Simulator
80% of readers judge a book by its thumbnail. We simulate the Amazon search grid to help you verify if your title is legible at 90px height, maximizing your Click-Through Rate (CTR).
Kindle E-Ink Rendering
Colors look different on paper than on screens. Our E-ink filter converts your RGB cover into 16-bit grayscale, ensuring your design maintains high contrast and sharpness on Kindle Paperwhite and Oasis.
App Dark Mode Check
With millions of users browsing in Dark Mode, your cover needs to pop against black backgrounds. Preview your design in the Amazon Shopping App's night theme to prevent visual blending or edge artifacts.
How to Generate a KDP eBook Cover (1600 x 2560 px)

Technical Specifications for Amazon KDP eBook Covers
Follow these strict technical requirements to ensure your eBook cover is approved by Amazon KDP without errors.
Dimensions & Ratio
1600 x 2560 pixels (Ideal)
The gold standard for KDP. While Amazon accepts smaller sizes, this dimension ensures the correct 1.6:1 aspect ratio and prevents blurriness on high-definition devices (Fire HDX, iPad Retina).
File Format
JPG / JPEG
Preferred format for eBooks. Files must not contain transparency. Do not upload PDF (reserved for Paperback only) or PNG with transparent backgrounds.
Color Profile
RGB (sRGB)
Strict requirement for digital screens. Covers uploaded in CMYK (print standard) may experience significant color shifting or rejection by the KDP converter.
Resolution
300 PPI (Minimum)
Although screens technically display at 72 PPI, Amazon applies compression. Starting with a source file of 300 PPI ensures crisp text and sharp edges after Amazon's internal processing.
File Size Limit
< 50 MB
The generated file is optimized to balance quality and size, ensuring fast upload speeds without hitting the KDP server timeout limit.
KDP Cover Guidelines: Avoid Rejection & Boost CTR
A technical checklist to ensure your eBook cover meets Amazon's metadata, quality, and content policies.
The "90px" Thumbnail Rule
80% of Amazon traffic is mobile. Covers with small text or low contrast become illegible when shrunk to thumbnail size (90px).
- High Contrast: Ensure title value contrast (test in grayscale).
- Genre Signaling: Use standard palettes (e.g., blue/black for Thriller).
- Single Focus: One central visual element.
Metadata & AI Disclosure
Inconsistency between your cover and book details, or failing to disclose AI usage, triggers immediate manual review or account flags.
- AI Policy (Critical): When KDP asks "Did you use AI tools?", you must select 'Yes' for the cover image. Choose the option "AI-generated". Hiding this can lead to a permanent ban.
- Title Accuracy: Text on the image (Title/Subtitle) must match your dashboard fields character-for-character.
- Clean Visuals: Do not hard-code pricing ("$0.99") or claims like "Best Seller" on the art.
UI Obstruction & Artifacts
Amazon overlays system badges. Important text in corners will be obscured.
- Respect Safe Zones: Text 50px away from corners.
- No Fake 3D: Upload flat 2D images only.
- Quality Standard: 300 PPI equivalent (2560px height).
Self-Audit Checklist
verify your cover against these critical points before uploading.
