What are overlay images

Overlay images refers to the method of layering one image over another for a picture-in-picture effect. With this method, you can combine multiple visuals within a single composition and enhance storytelling or design impact.

The primary types of overlays you'll encounter include:

  • Full overlays: The top image covers the base completely, but its adjusted blending mode or opacity is reduced so that the lower layer shows through it, best used for textures or light leaks.
  • Partial overlays: The top image only covers part of the base, commonly used for logos, watermarks, or simple picture-in-picture boxes.
  • Transparent overlays: These rely on a transparent background in the overlay (like PNG) or high opacity adjustments to subtly blend the image onto the base, creating effects like ghosting or double exposure.

Beyond simple layering, CapCut Web's cutting-edge AI design feature introduces a revolutionary way to blend visuals.

Method 1: How to overlay images naturally using CapCut Web's AI design

Creating seamless image overlays no longer requires manual masking or layering skills. With CapCut Web's AI design feature, you can merge photos intelligently—preserving lighting, depth, and perspective for a natural, cohesive look. Here's how you can do it step-by-step:

    STEP 1
  1. Access AI design feature

To begin, open the CapCut Web in your browser and log in to your account. From the homepage, look for the "AI tools" menu on the left side of the screen, which houses CapCut Web's more advanced, generative features. Within this menu, select the "AI design" option. This action opens the dedicated workspace for AI-powered image creation, which is essential for this type of natural blending.

Navigate to AI design feature
    STEP 2
  1. Upload images and prompt

Click the "Upload image" button highlighted in the red box to add the photos you want to overlay. You can upload both the base image (background) and the overlay image you want to blend. In the same field, enter a creative prompt that describes your goal. Once ready, hit the Send button to let CapCut Web's AI automatically generate your natural image overlay.

Upload images, prompt and generate
    STEP 3
  1. Refine the visuals

After your overlay is generated, you can use prompt-based editing to guide further improvements. Simply rephrase or extend your prompt — for example, "make the lighting warmer" or "soften the edges between both images" — and CapCut Web's AI will instantly adjust the design to match your intent.

Enhance the design with prompts

For finer control, explore the editing tools available on the top panel. You can tweak brightness, contrast, and saturation, adjust blending strength, or reposition elements for better balance. These tools help perfect the visual harmony between both images, ensuring your final overlay looks natural and professionally composed.

Once your overlay looks perfect, click the Download button to export your image in high resolution. You can choose the preferred format (like JPG or PNG) depending on where you'll use it. For quick sharing, CapCut Web also allows you to share directly to social media. This makes it easy to showcase your finished overlay instantly—whether for a post, project, or portfolio.

Method 2: How to add a picture inside a picture using CapCut Web

Ready to learn how to add a picture to a picture in just a few clicks? Let's explore the easy steps to begin creating amazing visuals with CapCut Web.

    STEP 1
  1. Upload your base image

Start by clicking the link above to sign in to CapCut Web. When you are logged in, click the "Create new" button to start a new project. Select "Image" and select your desired canvas size.

Start a new project

In the editor, navigate to the "Upload" tab on the left-hand sidebar. You can upload images from your computer, Dropbox, Google Drive, or even scan a QR code on your mobile phone. Drag and drop the image you'd like to set as the background or base onto the canvas.

Upload your base image
    STEP 2
  1. Add the overlay image

Now, upload your second image, which will be the overlay. Once uploaded to your media library, simply drag and drop this second picture directly onto your canvas. It will automatically be placed on a new, separate layer on top of your base image.

Import your overlay image
    STEP 3
  1. Adjust parameters

First, ensure your base image is well-arranged. If it does not automatically occupy the background, right-click the image and select "Set as background." In case your overlay needs to be arranged differently, you can right-click on it and apply the "Layer arrangement" option to move it front or back.

Arrange layers and set background

Then, click on the overlay picture to select it. Use the corner handles to resize and the on-screen tools to position the image exactly where you want it. In the editing panel, adjust the "Opacity" slider to control transparency. You can further experiment with the "More" tab to manipulate colors, brightness, and contrast to achieve the exact tone and blend in with the background.

Adjust position, size and opacity
    STEP 4
  1. Preview, export and share

Once you're happy with the way you've merged the two pics, click on the "Download" button, found in the top right corner. Choose your preferred settings (e.g., size and format, e.g., JPG or PNG and quality), and then click "Download" again to save your finished picture overlay or share directly to your social media platforms.

Key features of CapCut Web for adding picture into picture

  • Prompt-based editing: Refine your overlay effortlessly using simple text instructions. With the advanced AI capabilities of Seedream 4.0, you can add, remove, or adjust specific visual elements by typing natural language prompts—like "soften the lighting on the face" or "blend both people evenly" and the AI automatically refines tones, lighting, and blending for professional, natural results.
  • Layer arrangement and management: Easily organize your overlay and base images using the layers panel. You can change the order (bring forward or send backward), hide layers, or lock them to prevent accidental edits while working on complex picture overlays.
  • Size and position adjustments: Precisely control the placement of your overlay image with intuitive drag-and-drop handles. Use the exact numerical inputs in the editing panel to fine-tune the scale, rotation, and alignment of your picture-in-picture effect.
  • Opacity and transparency controls: Achieve seamless blending effects by adjusting the transparency of your overlay image. The simple opacity slider lets you create subtle watermarks, soft light effects, or striking double exposures where the background shows through.
  • Color, light, and detail tweaks: Perfectly match the aesthetics of your base and overlay images with comprehensive adjustment tools. Tweak brightness, contrast, saturation, and exposure directly on the overlay to ensure a harmonious final picture.
  • Export and sharing options: Once your pic overlay is complete, CapCut Web offers quick, high-resolution downloads. Choose from multiple file formats (like JPG or PNG) and share your finalized merged picture directly to your preferred social media platforms.

Pro tips for stunning photo overlays

Once you know how to overlay images, these professional tips will help you take your creations to the next level. Leverage CapCut Web's powerful tools to ensure your photo overlays look stunning and seamless.

  • Match the lighting and color: Ensure both images have consistent lighting and tones for a seamless blend. CapCut Web's color correction and brightness tools let you adjust exposure, contrast, and temperature to make your overlays look cohesive.
  • Use opacity for subtlety: Don't make your overlay too dominant; subtlety is key for many artistic effects. On CapCut Web, you can easily access the opacity slider to dial down the transparency, which is perfect for adding soft textures, light leaks, or creating a ghostly, transparent overlay effect.
  • Experiment with blending modes: Beyond simple transparency, blending modes dictate how the colors of the overlay image interact with the base image. CapCut Web offers various blend modes (like Multiply, Screen, or Overlay) that instantly create striking artistic interactions, giving your photos depth and drama.
  • Align and resize carefully: When creating a picture-in-picture effect, precision matters. Use CapCut Web's intuitive resizing handles and rotation tools to ensure the overlay is perfectly scaled and positioned relative to the background, avoiding awkward cropping or misplaced elements.
  • Leverage background removal: If you only want to superimpose a specific object or person, use CapCut Web's powerful "Remove BG" tool. This feature instantly cuts the subject out of the overlay image, allowing you to flawlessly drop them onto your new base picture without any messy edges.

FAQs

    1
  1. What is the difference between a photo overlay and a collage?

A photo overlay places one image on top of another to create a single layered composition, often used for effects like picture-in-picture, logos, or double exposure. A collage, on the other hand, arranges multiple images side by side or within a grid layout. With CapCut Web's AI design powered by Seedream 4.0, you can go beyond manual layouts — simply describe your desired composition in natural language, and the AI intelligently arranges or blends your images for a polished, creative finish.

  1. Is it possible to overlay images online without watermarks?
