AI Cover Image Creator
A useful cover image communicates the topic before anyone reads the title. CrePal's image creator takes a text description and produces a visual starting point. Generate the artwork first, then place final typography and platform-specific crops in a layout tool where you can verify safe zones.
What makes a strong cover image for blogs, videos, or podcasts?
Pick one focal subject, one mood and one dominant contrast. A blog cover needs room for a headline; a playlist cover must read at small square size; a video thumbnail needs a clear subject at a glance. Write those constraints into the prompt before choosing a style.
How do you choose the right size for each platform?
Make the destination format part of the brief. YouTube currently recommends 3840 × 2160 pixels at 16:9 for a standard video thumbnail, and 2160 × 3840 at 9:16 for Shorts. Build those final canvases in a layout tool; a blog, ebook or playlist cover needs the dimensions of its own publishing surface. Keep faces and logos away from crop edges.
Where should text and faces sit inside safe zones?
Leave a low-detail area for the headline. Put a face or product where it will not be covered by platform UI. Check the cover at full size and as a tiny preview; readable contrast matters more than fine texture at thumbnail scale.
How do you keep a cover image consistent with your brand?
Specify a repeatable palette, lighting direction and visual motif. Keep a short creative brief with those decisions so subsequent covers share a family resemblance. Review each generated image for unintended marks or inaccurate objects before applying your brand assets.
Can AI generate multiple cover concepts from one brief?
Yes: vary one element at a time, such as composition, background or accent color, while keeping the same subject and palette. Select the best direction before typesetting, and build a separate final layout for each cover.
Example prompt
Create cover artwork for an ebook about urban gardening: one vivid balcony planter, warm morning light, deep forest-green and terracotta palette, generous clean space on the left for a title, no lettering or logo.
Worked example: one topic, two cover placements
Imagine a gardening guide that will appear both as a blog card and a video thumbnail. Keep the same balcony planter and color palette, but make two final compositions. For the blog card, allow room for a longer headline and check how the site crops the card on mobile. For the video version, bring the planter closer, reduce background detail and use a shorter title that survives a small preview. Generate the art without text, then typeset both titles in a layout tool. Compare the two exports side by side: they should look related, yet each should communicate its topic at its actual display size.
Cover review checklist
- Is the main subject recognizable when the cover is reduced to a small card?
- Does the headline remain readable over the lightest and darkest parts of the art?
- Are faces, logos and important words clear of the destination's crop and interface overlays?
- Does the image accurately represent the article, episode or video it introduces?
Next step
Generate the cover art in CrePal's image creator, then set the headline and destination-specific canvas in a layout tool. Preview the finished cover at its actual display size.
Frequently Asked Questions
For a standard video, YouTube's custom thumbnail guide currently recommends 3840 × 2160 pixels at 16:9, with a minimum width of 640 pixels. Build and check the final file in a layout tool; CrePal artwork alone does not set that export size.
Yes. Generate the background art, then add exact title text in a design tool so spelling, font and legibility stay under your control. Keep the title editable and preview the finished cover at thumbnail size; a phrase that reads on the canvas can disappear in a feed.
You can create a series by generating each cover separately from a shared brief. Keep one palette and subject direction, then make a separate prompt variation for each cover. Compare the set at thumbnail size and add the final titles in a layout tool.
For exact production text, usually not. Generate a clean background with space reserved for copy, then add the headline as editable text. This makes spelling, font licensing, contrast and later title changes easier to control.
Fine texture and small objects disappear when the image shrinks. Reduce competing details, enlarge the one meaningful subject and test the finished layout at the size where readers will first see it, not only on the editing canvas.
