How it works

Upload your banner image

Drop in your Twitch profile banner. Twitch banners display at 1200x480 pixels. PNG or JPG up to 7MB. Upload at the full recommended resolution for best results.

Expect: Color and sharpness enhancements: 20-30 seconds. Background changes or complex edits may take slightly longer.
Describe what to enhance

Type what needs to improve: 'make the colors more vivid and punchy, increase contrast, and sharpen the overall image.' Be specific about what you want the banner to feel — energetic, clean, dark and moody. No marking needed.

Tip: Twitch banners are wide and viewed on desktop monitors. Colors need to pop at banner scale. Include adjectives like 'bold,' 'high contrast,' or 'dramatic' to guide the AI toward the right intensity.

Copy one of these to get started:

General banner polish make the colors vivid and punchy, increase contrast, sharpen details across the entire banner for a polished professional look

Gaming or dark aesthetic deepen the shadows, increase contrast dramatically, make colors bold and saturated — create a dark dramatic gaming atmosphere
Try This →

Bright or clean streamer style brighten the overall banner, enhance colors to be clean and vibrant, and give it a fresh modern look without over-processing
Try This →

Character or avatar focus sharpen and enhance the character or artwork in the center, make colors more vivid, and keep the background clean and not distracting

3 more prompts

Color scheme consistency enhance the banner so the colors feel cohesive and harmonious — boost saturation and balance the warm and cool tones
Try This →

Background gradient improvement deepen and enrich the background gradient colors, increase the vibrancy of the overall banner while keeping text areas clean and legible
Try This →

Overlay-ready banner enhance the banner colors and contrast, and darken or simplify the left edge so profile info and overlays will be legible on top
Try This →
Check at banner scale

Review the result at full width. Check that the overall color and contrast read well across the wide banner format. Use the before/after slider to compare.
Refine a specific area if needed

If the AI enhanced the background but missed a face or focal element, tap a marker on that area and regenerate. Optional — most banner enhancements work without markers.

Tip: Use markers when your banner has a complex composition — a character on one side and a dark gradient on the other, for example.

If something looks off

AI changed the wrong area or something I didn't want changed

Why: The AI couldn't determine exactly which part to target from description alone.

Try: Tap a marker on the specific area you want to change, then regenerate with the same prompt

Try This →

Tip: Markers are essential on complex banners with multiple zones — character, background, text area. Use them to isolate the target.

Colors look oversaturated and unnatural

Why: The AI pushed saturation beyond realistic or branded levels.

Try: Regenerate with 'enhance with vivid but natural colors — rich and saturated but not neon or oversaturated'

Try This →

Tip: Adding 'but not oversaturated' gives the AI a clear upper bound on how far to push colors.

Text or username overlay is now hard to read

Why: The enhancement increased background complexity in the text zone.

Try: Add 'keep the background area clean and simple so text overlays remain readable'

Try This →

Tip: If you have specific text zones, describe them: 'keep the left third of the banner dark and clean for channel name.'

Banner looks good zoomed in but odd at full banner scale

Why: Wide format banners are viewed at a very different scale than standard photos.

Try: Regenerate with 'enhance for wide banner format — consistent color and contrast across the full width'

Try This →

Tip: Preview your exported banner at 100% in a browser tab before uploading to Twitch to catch any edge issues.

Enhancement created artifacts or noise in dark areas

Why: The AI brightened shadow areas, revealing underlying image noise.

Try: Use 'enhance with smooth clean shadows — no noise or grain, keep dark areas deep and clean'

Try This →

Tip: 'Smooth clean shadows' and 'no grain' are the most reliable phrases for preventing AI-introduced noise.
