Frequently Asked Questions
What is an ebook cover mockup?
An ebook cover mockup is a realistic 3D visualization of your book cover design placed on a digital book model. It helps authors, designers, and marketers showcase their ebook covers in a professional, eye-catching way—ideal for websites, social media, Amazon listings, and promotional materials.
What image size works best for the cover?
For optimal results, use an image with a 2:3 or 3:4 aspect ratio (typical book cover proportions). Recommended minimum resolution is 600×900 pixels. Our tool automatically scales your image to fit the 3D book cover area while maintaining aspect ratio. JPG, PNG, and WebP formats are all supported.
Can I download with a transparent background?
Yes! Select the "Transparent" background option, and your downloaded PNG will have a transparent background. This is perfect for placing the 3D book mockup directly onto your website, in design compositions, or on marketing materials without any background box.
Is this tool free for commercial use?
Absolutely. All mockups you create with this tool are yours to use for any purpose—commercial or personal. There are no watermarks, no attribution required, and no hidden fees. Create unlimited mockups for your book covers, client projects, or marketing campaigns.
How do I get the best 3D book mockup result?
For professional-looking results: (1) Use a high-resolution cover image with clear typography, (2) Choose a spine color that complements your cover design, (3) Add a spine title for extra realism, (4) Experiment with different background options to match your use case—transparent for versatile placement, gradient for a premium feel.
What's the difference between this and Photoshop mockups?
Our online tool is instant, free, and requires no software installation. While Photoshop offers more advanced customization, our tool delivers professional-grade 3D book mockups in seconds—directly in your browser. You can adjust colors, spine text, and backgrounds on the fly and download immediately.
Can I change the 3D angle of the book?
The current version features a classic isometric 3D book view—the most popular and versatile angle for ebook showcases. This angle clearly displays the front cover, spine, and book edges, giving a natural and professional presentation. We're working on adding more viewing angles in future updates.
