Free 3D Book Cover Generator

Upload your flat book cover image (JPG or PNG) to the generator above. Choose a viewing angle, adjust the page count for realistic thickness, pick a background color, and click "Download PNG." The entire process takes under 30 seconds, requires no account, and produces a watermark-free image you can use commercially.

For the sharpest results, use a cover image that's at least 1600 x 2560 pixels, which is the standard Amazon KDP cover dimension. The generator accepts any image size, but higher resolution files produce crisper mockups, especially when exporting at larger canvas sizes like the Amazon A+ (1600x2560) or Pinterest (1000x1500) presets.

Yes. The mockups you create here are yours to use anywhere, including Amazon KDP product listings, A+ Content, author pages, and advertising campaigns. There are no watermarks, attribution requirements, or licensing restrictions. Many authors use the "Front" or "Hero" angle presets specifically for their Amazon listings because those angles clearly show the cover while adding professional depth.

The page count slider controls the physical thickness of your 3D book. A 50-page chapbook will appear slim, while a 600-page novel will have a visibly thick spine and page edges. This adjusts the spine width, the top/bottom depth, and the paper-edge simulation on the side opposite the spine. Set it to match your actual book's page count for the most realistic result.

The auto-generated spine extracts the dominant color from the left edge of your cover and applies it as a gradient. This works well for most books. If your cover's spine design includes text, logos, or specific artwork (common with traditionally published covers), you can upload a separate spine image for pixel-perfect accuracy. The spine upload is optional; if you skip it, the color-matched gradient is used automatically.

You can rotate the book to any angle. The six preset buttons (Front, Angled, Hero, Tilted, Flat Lay, Wide) are starting points for common viewing angles. After selecting a preset, click and drag anywhere on the preview area to rotate the book freely in 3D space. The rotation includes momentum, so if you drag quickly and release, the book will continue spinning briefly. Touch drag works on mobile devices too.

Use the Instagram preset (1080x1080) for square posts on Instagram, Facebook, and LinkedIn feeds. For Pinterest pins and TikTok thumbnails, use the Pinterest preset (1000x1500) for a tall vertical ratio. YouTube thumbnails work best with the YouTube Thumb preset (1920x1080). For Amazon A+ Content and high-resolution author website graphics, use the Amazon A+ preset (1600x2560). You can also enable "Transparent background" to layer the mockup over custom backgrounds in your design software.

Completely free with zero catches. There's no account signup, no email gate, no download limit, and no watermark on any exported image. All rendering happens in your browser, which means your cover images never upload to a server. You retain full ownership and commercial rights to every mockup you create.

The preview uses CSS 3D transforms rendered in your browser, while the download uses a custom 2D canvas renderer that translates the current rotation angle into a perspective projection. The two methods produce very similar results, but slight differences in shadow placement or skew intensity are normal. For best results, choose an export size that matches the aspect ratio you need rather than cropping afterward.

Yes. Use the "Back Cover" upload option in the controls panel to upload a separate back cover image. Once uploaded, rotate the book past 90 degrees to reveal the back side with your uploaded artwork. If you don't upload a back cover, the tool displays a neutral dark gradient as the back face. This feature is useful for showcasing wraparound cover designs or for creating promotional graphics that show both sides of the book.
