Book Cover Maker
Design a front cover and spine, then download a print-resolution PNG — 6 × 9 in alone exports at 1800 × 2700 px. Everything renders in your browser; your file is never uploaded.

Spine
240 pages → 0.600 in spine, drawn 58 units wide in this trim size. Even 240 pages is required for print (odd page counts need a blank).
Export
Output: 3781 × 2700 px (back + spine + front, flat wrap). Rasterising is capped at 38 megapixels so the tab cannot run out of memory.
Live preview
6 × 9 in · Centred ClassicThe preview and the download are the same SVG, so type wraps identically. Uploaded artwork is embedded as a data URL before it enters the canvas — that is what keeps the exported PNG untainted.
Optional: upload artwork to turn this into a photo cover. Placement, fade, blend and scrim controls appear with it.
About this tool
Book Cover Maker designs a front cover, spine and back panel in real trim proportions — 6 × 9 in, 5 × 8 in, 5.5 × 8.5 in or a 1600 × 2560 e-book canvas — and exports the whole wrap as a print-ready PNG at up to 400 dpi. It runs entirely in the browser: your typing and any uploaded artwork stay on your device, and nothing is sent to a server.
Spine width is calculated from your page count and paper stock, and export size follows the trim you pick — 6 × 9 in alone becomes 1800 × 2700 px at 300 dpi. Rasterising is capped at 38 megapixels so a large canvas cannot exhaust memory, and the tab tells you when that ceiling trims the resolution. Type is set in system fonts, so the PNG matches the preview exactly.
A spine width from a page count plus paper stock is an estimate — always confirm the final figure with your printer before submitting files, and remember that print shops expect CMYK with a bleed, which this PNG designer does not produce.
