Before you can transform your image with a stunning new backdrop, you need a clean slate.

Once you've selected the image, tap on "Next" to upload it. Its AI will automatically detect the main subject, be it a person, product, or object, and cleanly erase the original backdrop with high accuracy. No need for manual masking or complex edits. After the removal is complete, tap the "check mark" and then tap "Export" to save your image with a transparent background. This isolated subject now serves as the foundation for your custom background.

Next, go back to the homepage. When you are there, tap on "Photo tools" and then select "Text to image." On the next interface, type in a detailed description of your background. You can type something like "sunlit garden with stone path," or "minimalist workspace with neutral tones." After that, tap on "Settings," select your "Image type" (either General or Anime), choose your preferred "Aspect ratio" based on your transparent image, and then use the precision slider to adjust the "Quality." Once everything is set, tap the "Check mark" and then tap "Generate" to create your background.

STEP 3
1. Layer and download the final composition

Once your new background has been generated, you will see four unique images. Tap on the one you like the most and then tap "Save" to download it to your phone. After that, go back to the CapCut App homepage again and tap "Photo editor," select the new background you just saved to your phone, and then upload it. Once uploaded, tap on "Add photo" at the bottom of your screen to upload your transparent image. Once it is uploaded, position the transparent image exactly where you want it in the background.

Pro strategies: Expert tips for realistic AI background integration

Achieving seamless and convincing results when adding AI-generated backgrounds to your images requires more than just selecting a nice scene. Here are expert-level strategies to help your edits look natural and professional:

• Match the lighting conditions

Lighting can make or break the realism of your image, and that is why you should always ensure the background you generate mimics the light source direction, intensity, and color tone of your original subject. If your subject is lit from the left with a warm tone, avoid placing it in a background where the lighting is from the opposite side or has a cool hue; it'll immediately look off. Another thing you need to consider is that if your subject is bright, your background should not be overly bright, so as to avoid overpowering the subject or creating an unnatural contrast.

• Consider perspective and scale

To create a realistic composition, maintaining consistent angles and depth is very important. If your subject is photographed from a low angle, slightly tilted, or from a side profile, the background you generate should also reflect that same viewpoint. Also, don't forget about the scale. Your subject should feel naturally proportioned within the scene. For instance, if you're placing a person on a beach, they shouldn't appear larger than nearby palm trees or look unnaturally small beside beach chairs. Matching both scale and perspective helps blend your subject smoothly into the new environment, avoiding jarring or unrealistic visuals.

• Use complementary colors

Color harmony plays an important role in making AI-generated background edits look natural and cohesive. When selecting or prompting a new background, choose tones that complement your subject's clothing and skin tone. For example, warm backgrounds often pair well with earthy outfits, while cooler tones improve neutral or pastel clothing. Be cautious of using overly saturated or mismatched colors because extreme contrasts or clashing palettes can make the subject appear out of place. Instead, aim for complementary shades that help the subject visually belong to the scene while still drawing just the right amount of attention.

• Maintain consistent quality

One of the easiest ways to ruin a good edit is with a resolution mismatch. A sharp, high-quality subject placed over a blurry or pixelated background instantly breaks immersion and reveals the edit. So, always ensure the background matches or exceeds the resolution and clarity of your main subject. This consistency helps blend elements naturally and keeps the final image looking polished and believable. When using AI tools, be proactive with your prompts. Include descriptors like "high-resolution," "4K quality," or "photo-realistic" to ensure the generated background holds up visually.

• Test multiple variations

One of the greatest strengths of AI editing tools is their speed and flexibility, so don't settle for the first result. You should take advantage of this by generating multiple background variations for your image. Experiment with different moods, lighting conditions, angles, and color schemes. For example, try a warm, golden-hour backdrop or a moody, overcast scene. This variety helps you compare how each option complements your subject's expression, clothing, or posture. Often, the most visually balanced and emotionally resonant background isn't the one AI suggests first; it's the one you discover through thoughtful iteration.
