PineTools and Canva are free web-based apps that make it easy to overlay and blend multiple photos from any device, including your PC, Mac, Android, and iPhone! GIMP is a free tool that has similar features and controls as Adobe Photoshop, including the ability to combine photos.

Using GIMP

PDF download Download Article
  1. This is a free photo-editing software that you can install on Mac or PC. If you don't already have it, download it now.
    • Windows β€” Go to gimp.org/downloads/ , click Download GIMP directly , double-click the downloaded setup file, and follow the on-screen instructions.
    • Mac β€” Go to gimp.org/downloads/ in your computer's web browser, click the appropriate link ( Intel or Apple Silicon ), double-click the DMG file, click and drag the GIMP logo onto the "Applications" folder, and follow any additional instructions.
      • On a Mac, you may need to verify the installation before you can install GIMP.
        • Using GIMP is more complicated than using a web-browser photo-editor like PineTools or Canva. You should only use this method if you need more editing capabilities than other services offer.
  2. This should be the photo you plan on overlaying on top of your base photo:
    • Click File.
    • Click Open...
    • Select the photo.
    • Click Open.
  3. This will allow you to save the cropped portion of your photo as clip art rather than as a cropped photo on a white background:
    • Click Layers.
    • Select Transparency.
    • Click Add Alpha Channel.
  4. Either press "M" on your computer's keyboard, or do the following:
    • Click Tools.
    • Select Selection Tools.
    • Click Free Select.
  5. Click and drag your mouse around the section of the photo that you want to add to your base photo.
    • Repeatedly clicking in a line around the selection instead of dragging will help achieve greater accuracy.
    • You'll need to connect the end of the line to the beginning of the line before you can continue.
  6. To highlight everything but the section you want to keep, press M to select the section, then press either Ctrl + I (Windows) or ⌘ Command + I (Mac).
  7. Press Del on a Windows computer, or press ⌘ Command + X on a Mac. You should see everything but the selected portion of the photo disappear, leaving behind a checkerboard background.
  8. Since you want to save this photo as a GIMP file rather than as a JPG or PNG, you'll use the Save As feature:
    • Click File.
    • Click Save As...
    • Enter a filename, then select the same save location as your base photo.
    • Click Save.
  9. Click the X in the top-right corner of the project window (top-left corner on Mac) to do so. The GIMP window should remain open and blank while the photo disappears. At this point, you can proceed with overlaying your pictures.
    • Now that you've cropped the pictures, you can overlay them.
  10. Using the dimensions from the photo that you found earlier, open a new project:
    • Click File.
    • Click New...
    • Adjust the "Width" and "Height" text fields.
    • Click OK.
  11. By opening both photos as layers, you'll be able to align them with each other:
    • Click File.
    • Click Open as Layers…
    • Select your pictures' location on the left side.
    • Hold down Ctrl (Windows) or ⌘ Command (Mac) while clicking photo names.
    • Click Open.
  12. To readjust the cropped layer's position, do the following:
    • Click Tools.
    • Click Transform Tools.
    • Click Move.
    • Click and drag the cropped layer.
  13. If you want to change the size of the cropped photo, do the following:
    • Click Tools.
    • Select Transform Tools.
    • Click Scale.
    • Select your cropped layer.
    • Click and drag the layer to resize it.
    • Click Scale.
  14. If your intention was to create an image in which you place another image to make it seem like the second image was part of the first image, you can proceed with flattening and exporting your project .
    • If you want to create a collage with different transparencies, proceed to the next part.

  1. Press either Ctrl + L (Windows) or ⌘ Command + L (Mac) to do so. The Layers window will pop up in the upper-left side of the screen; you should see both the base photo and the cropped layer appear in the photo.
  2. Click the layer preview that corresponds to your cropped layer.
  3. At the top of the Layers window, click the downward-facing arrow to lower the opacity of the cropped layer.
    • You may have to lower the opacity to 20 (or lower) to achieve your desired effect.
  4. Click the Image tab, then click Flatten Image in the resulting drop-down menu. This will combine all of the photos' layers into one image.
    • This step is necessary before you can export the image to an image file.
