The title runs to eleven words, so the layout sets it on two lines in the upper area and shrinks only until the lines fit — never below the legible floor. The upper sky stays empty by instruction, which is why white type holds against it at 120 px.
Three text levels, one reading order. The title is the largest, the subtitle sits under it at roughly a third of the size, and the author closes the stack. The flat upper band keeps every line inside the safe margin without a scrim.
A light typeface on a pale field is the hardest thumbnail case. The layout answers with size, line spacing and a near-white ground rather than heavier lettering, and the motif is deliberately small so it never competes with the words.
Layer the words over the art
Book title, author and artwork are layered; a portrait front cover still reads its title at a 120 px wide preview. That is the whole test. A store listing, a library grid, and a recommendation row all shrink a cover to roughly a thumbnail, and at that width a title written into the artwork becomes texture: letterforms blur into the background, a painted serif loses its contrast, and the words that identify the book stop being words.
Layering is what keeps the title readable. The artwork sits underneath as a single image with its own composition and its reserved quiet area. The title, subtitle, and author are drawn above it as live type at a size the layout chooses for the canvas: large enough to hold at thumbnail scale, small enough to stay inside a safe margin. Because the type is not part of the picture, it keeps its edge, its weight, and its colour at every size, and it can be re-set without touching a single pixel of art.
IMG AI draws the artwork text-free and typesets the words locally. The layout module picks the font size from the canvas, wraps a long title over several lines, keeps the title above the subtitle above the author, and never drops a character you typed. The same layout runs the 120 px preview in the workbench and the 1600 × 2560 export, so the cover you approve is the cover you download.
A generative model paints letters as pixels. At full size that can look convincing; at 120 px the strokes merge into the background and a single misspelled character cannot be fixed without redrawing everything. Keeping the type live means the title is always crisp, always spellable, and always editable after the fact.
The type cannot distort, curve around an object, or interlock with the illustration the way a hand-lettered cover can. Artwork and words stay in two planes. For a cover that needs lettering melted into the art itself, export the base image and finish it in a design tool.
The type needs somewhere to sit. Each genre asks the model for a reserved area — a flat sky, an untextured band, a quiet lower edge — so the title has contrast to land on. A busy artwork with no quiet zone forces a smaller title, and a smaller title is the thing that fails at thumbnail size.
Fill in the title, author, genre, and visual brief, then generate a text-free base image. From that point the typography is independent: edit the title, the subtitle, the author or the text colour and the canvas re-lays the words over the same artwork in the browser. Nothing is sent to the model, so nothing is charged.
A new base image is only created when you press generate again, and the button shows the credit cost first. That is the trade this page is built around: one paid artwork, as many typographic revisions as the title needs. Case two below shows the same separation in reverse — the subtitle and author carry the hierarchy while the artwork stays quiet.
Cover work this is built for
One base image costs 20 credits. Retyping the title, editing the subtitle, changing the author, switching the text colour, and exporting again are all local, free, and unlimited on that artwork.
Six genres, each with its own palette and a negative-space instruction. The genre changes the picture and where the quiet area sits; it never changes the typeface, the hierarchy, or the layout rules.
The workbench preview and the export share a single layout module. The 120 px thumbnail is the same geometry scaled down, so a title that fits the preview is the title in the file.
Each genre carries a palette and a negative-space instruction. The genre shapes the picture, not the typography.
Four routes produce a book cover. They differ in where the words live, which decides what you can change later without paying again.
One text-free artwork plus a live type layer you can re-set for free, inside an image account you already have.
Write the title, subtitle, author, pick a genre, describe the artwork, confirm 20 credits, generate once, then re-set the type and export as often as needed.
The typography is disciplined but conventional: centred lines, a fixed serif hierarchy, and no lettering that bends into the illustration.

Any typo, any change of title, and the whole cover is redrawn. Small type tends to soften first, which is exactly what a thumbnail cannot afford.
A fixed layout with editable text boxes, when every element must stay movable and on-brand.
Choose a sized template, replace the text and imagery, and export. Layout, safe areas, and export sizes are predefined.
You stay inside the template family you picked, and original artwork means supplying or sourcing the image yourself.
A bespoke cover with hand-lettering or illustration, when the cover is the product and the budget is there.
Brief, concepts, revisions, and a final handoff with layered source files.
The strongest result and the slowest route. Every later change is another round with another person.
Pick by what you need to keep changing. If the artwork is settled and the words are still moving, a layered local type layer saves the most work; if the lettering itself is the design, a designer is the right call.
Three tools, three output shapes. Pick by the asset and the amount of type it has to carry.

|---|---|---|---|
| Best for | A portrait front cover whose title must survive a thumbnail | An event or campaign poster with a headline | A flexible image with no fixed typographic job |
| How text is handled | Typeset locally on a separate layer, free to change | Rendered into the poster image | Not handled; the prompt describes the picture only |

| What it will not do | Curve or distort lettering into the artwork | Re-set a headline without a new render | Guarantee a readable text hierarchy |
No. The model is asked for a text-free illustration and the instruction explicitly forbids lettering, captions, numbers, and logos. The title, subtitle, and author are drawn on a separate canvas layer over the artwork, using a layout that decides the font size, the line breaks, and the position inside a safe margin.
Yes, and it costs nothing. Editing the title, subtitle, author, or text colour re-runs the layout in your browser over the artwork you already paid for. A new base image is only created when you press generate again, and the button shows the 20-credit cost before that happens.
Long titles wrap so the words stay large enough to read at thumbnail size. The layout reduces the font size only until the lines fit the safe margin, then breaks the title across lines; a single very long word is broken at character boundaries rather than clipped. If the text still cannot fit at the smallest legible size, the workbench says so and asks you to shorten it instead of cutting characters.
The export is a 1600 × 2560 PNG, a 5:8 portrait front cover, drawn from the same layout you see in the preview. That is a screen-listing shape for ebook storefronts and reading apps; it is not a print-ready file and does not include a spine, back cover, or bleed.
No. A genre changes the artwork: it supplies a palette and a negative-space instruction so the base image leaves a quiet area for the words. The typeface, the hierarchy, and the wrapping rules are the same for every genre, which is what keeps the title readable at 120 px regardless of the artwork.
The reserved credits are returned and the title and brief stay in the form so you can retry. If the connection drops mid-task, the workbench recovers the same paid task instead of starting a second one, and the run stays visible in My Creations.
