How to use Book Cover Generator
Upload your image
JPG, PNG or WEBP. If the asset is going to be cropped several ways, start from the widest, highest-resolution version you have.
Choose the platform and shape
Square, portrait, wide, circle-safe, bold or minimal. The choice sets the ratio and where the subject sits inside it.
Download and post
Correct dimensions, full resolution, no watermark. It uploads without the platform re-cropping it for you.

Why use Book Cover Generator
What Book Cover Generator does
Cover art that suits the genre.
One source, every shape
Generate square, portrait, wide and circular versions from a single upload.
Full resolution
Enough resolution that the platform's own compression does not visibly degrade it.
Correct dimensions per platform
The right ratio and pixel size, so the platform does not recompress and re-crop the image on upload.
Circle-safe composition
Avatars are masked to circles almost everywhere. Composing for that keeps the head centred and the corners expendable.
Safe areas respected
Cover images have a profile photo over one corner and buttons over another. The subject is placed clear of both.
What Book Cover Generator changes
Create book cover artwork: a genre-appropriate central image, strong tonal composition, a clear area for title and author, and a finish that reads well as a small thumbnail.
Your face, bone structure and skin tone are held fixed on every generation — only what is described above is changed.
Book Cover Generator for every slot a profile has
A profile is a set of images with different jobs. Each one is cropped, masked and overlaid differently.
Thumbnails
High contrast, one clear focal point, and space for a short piece of large text.
Link previews and OG cards
The 1200×630 card that appears whenever a link is shared anywhere.
Profile pictures and avatars
Circle-safe, legible at 40 pixels, recognisable as the same person or brand across platforms.
Banners and cover images
Wide, composed around the elements the platform lays over them.

Benefits
No subscription
Credits are a one-time purchase, they never expire, and nothing renews on its own. Buy once and use them whenever.
Two models to choose from
Nano Banana and GPT Image handle the same job differently. If one result is not right, the other model often is.
Every aspect ratio
Square, 4:5, 9:16, 16:9 and more, chosen before generating so nothing important gets cropped away afterwards.
Full resolution, no watermark
The download is the full generated image with nothing overlaid — usable in print, in a listing or commercially.
The free tools stay free
Compress, convert, crop, resize, rotate and the rest run on your device, unlimited, with no account and no credit cost.
What people use it for
What it is mainly used for
Cover art that suits the genre. Pick a style, choose a model, and download the result at full resolution with no watermark.
A new profile photo across every platform
One portrait, composed correctly for a circular avatar, a square post and a wide banner.
Channel and page branding
Banner, avatar and thumbnail that read as one identity.
Video thumbnails
The image that determines whether a video is clicked, with space for a few large words.
Event and launch announcements
The same announcement in every ratio each platform needs.
Prompt ideas
Say where the subject should sit and where the text is going. Social composition is mostly about reserving space, and a prompt that does not mention the text is the reason the headline ends up over someone's face.
Say where the subject goes
"Subject on the left third, empty space on the right" is the single most useful instruction for anything with text on it.
Mention the circular crop
"Composed for a circular avatar, head centred, nothing important in the corners".
Reserve the text area
"Leave the upper third clear for a headline" — otherwise there is nowhere for the type to go.
Ask for thumbnail legibility
"High contrast, readable at 100 pixels wide", because that is the size most people will first see it.
Set the ratio explicitly
"9:16 vertical" or "1200x630". Pick it before generating; cropping afterwards loses part of the frame.
Keep the brand colours
"Use a deep orange and near-black palette" keeps a set of assets looking related.
More about Book Cover Generator
Upload, pick the platform and the shape, and download. Each generation costs 2 credits from a one-time pack, so producing the same asset in four ratios is a few cents rather than an afternoon in a design tool.
Every platform crops differently, and each one crops in a way that is easy to forget until it has already happened. A rectangular avatar masked into a circle loses the top of someone's head. A cover photo has a profile picture sitting over one corner. Book Cover Generator composes for the shape the image will actually appear in.
The size that matters is the smallest one. Most feed images are seen first at a couple of hundred pixels, and many at forty. Anything depending on fine detail or low contrast simply disappears at that scale, which is why the strongest social images are almost always the simplest.
Getting the best result from Book Cover Generator
- Check any cover image against where the platform overlays the profile photo and buttons.
- Look at the result at thumbnail size. If it does not read at 100 pixels, it does not work in a feed.
- Ask for space for text instead of asking for the text itself; add real type afterwards.
- Keep a consistent palette across avatar, banner and posts — consistency is what reads as a brand.
- Export at the platform's stated dimensions so its own compression has less to do.
- For stories, keep everything important out of the top and bottom sixth of the frame.
- Generate a few variants and look at them in the actual feed before choosing.
- Keep the source image; the next platform will want a different shape.
