KakaoTalk is South Korea's dominant messaging platform, and KakaoTalk Channels are the primary way brands communicate directly with customers — similar to Facebook Pages or Instagram business profiles, but built into an app used by over 47 million people. The channel cover image is the first visual a subscriber sees when they visit the profile page.
Most brand channels set a cover image once and leave it for months. Hiring a designer for every seasonal update is expensive, and doing it manually takes time. I tried creating KakaoTalk channel cover images with XBRUSH — from canvas setup to final export took about five minutes.
KakaoTalk Channel Cover Image Specifications
At a Glance: The recommended size for a KakaoTalk channel cover image is 1080×720px (landscape). XBRUSH supports custom canvas sizes, so the dimensions can be entered directly at the start of the generation workflow.
The cover image appears as a horizontal banner at the top of the channel profile. On mobile — where most KakaoTalk users browse — only the center portion of the image is visible. Placing key brand elements in the center and leaving breathing room on the sides ensures nothing gets clipped.
- Recommended size: 1080×720px
- File format: JPG or PNG
- Maximum file size: 2MB
- Key elements should be center-aligned (safe zone: roughly the middle 60%)
Creating the Cover Image in XBRUSH
At a Glance: Start a new project in XBRUSH, set the output size to 1080×720px, then enter brand keywords as a prompt. Uploading a reference image alongside the prompt helps lock in the exact mood before generating.
Step 1: Set the Canvas Size
Open XBRUSH and start a new project. In the image generation panel, set the output size to 1080×720px using the custom size input. This matches the KakaoTalk channel cover spec exactly, so the result is ready for direct upload without cropping or resizing.
Step 2: Write a Brand Mood Prompt
Translate the brand's visual identity into a set of descriptive keywords. Below are prompts used for different industry categories.
Prompt (Beauty): "luxury skincare brand, soft pastel pink, minimalist, clean background, glass texture, product flat lay, high-end beauty aesthetic"
Prompt (Cafe): "cozy cafe interior, warm latte, autumn atmosphere, wooden table, soft natural light, lifestyle photography"
Prompt (Fashion): "modern fashion brand, editorial style, neutral tones, studio lighting, minimal composition"
Step 3: Anchor the Style with a Reference Image
If there is a specific visual direction in mind — a competitor's channel image, a saved Pinterest board, or a brand style guide screenshot — uploading it as a reference image gives the AI a visual anchor. The result tends to match the tone and composition more precisely than prompt text alone.
Step 4: Add Brand Elements in the Canvas Editor
Once a satisfying result is generated, move to the canvas editor. A brand logo, channel name text, or promotional message can be added as a separate layer on top of the generated image. Export as PNG or JPG and upload directly to the KakaoTalk channel settings.
Prompt Keywords by Industry
At a Glance: Different industries have distinct visual expectations for brand channels. The table below summarizes recommended mood keywords and common mistakes by category.
| Industry | Recommended Keywords | Keywords to Avoid |
|---|---|---|
| Beauty / Cosmetics | soft pastel, glass texture, clean, luxury, flat lay | dark, grungy, chaotic |
| Cafe / F&B | warm, cozy, natural light, wooden, lifestyle | cold tone, sterile, white studio |
| Fashion / Apparel | editorial, neutral, minimal, studio, high-fashion | busy background, colorful clutter |
| Interior / Home Decor | Scandinavian, earthy, ambient light, serene | crowded, busy pattern |
| Pets | playful, bright, warm, friendly, natural | dark tone, formal |
Why Updating the Cover Image Seasonally Matters
Channel subscribers notice when nothing changes. A cover image that has not been updated in months signals to visitors that the channel may not be actively managed. Swapping the cover image at the start of a seasonal promotion or new product launch refreshes the channel's energy without any structural change.
With XBRUSH, a seasonal variation takes a few minutes. Rather than starting from scratch, the same prompt can be modified with seasonal descriptors — cherry blossoms and pastels for spring, ocean blue for summer, red and gold for the winter holiday season.
Frequently Asked Questions
What is the recommended size for a KakaoTalk channel cover image?
The recommended size is 1080×720px in landscape orientation. The file should be JPG or PNG and under 2MB. XBRUSH supports custom canvas sizes, so entering 1080×720px at the start of the project produces an image that matches the spec exactly.
Is design experience required to create a cover image?
No. XBRUSH generates images from text prompts. Entering a combination of industry type and mood keywords — for example, "luxury skincare, soft pastel, clean background" — is enough to get a starting result. Uploading a reference image alongside the prompt improves accuracy further.
Can the canvas size be set to 1080×720px directly in XBRUSH?
Yes. The image generation panel includes a custom size input field. Entering 1080×720px produces output in exactly that resolution, ready for KakaoTalk channel upload without resizing.
Can a brand logo or text be added to the generated image?
Yes. After generating the background image, the XBRUSH canvas editor allows adding logo files and text as separate layers. The completed file can be exported as PNG or JPG.
Is it necessary to create a new image for each season?
Not necessarily. XBRUSH's inpainting and background replacement features make it possible to update only the background or color tone of an existing image rather than starting over. Preparing spring, summer, autumn, and winter versions in one session is a practical approach.
How often should a KakaoTalk channel cover image be updated?
Once per quarter is a reasonable baseline, with additional updates timed to seasonal promotions or new product launches. Updating at least two to three times per year signals to subscribers that the channel is actively managed.
Is XBRUSH free to use?
XBRUSH provides free points upon signup. A few cover image variations can be generated using the free allowance.
