    Note

    Each upload can include up to 1,000 images in JPEG or PNG format. Individual file sizes must not exceed 100 MB.

  4. After the images are uploaded, they will be displayed under the Images tab. Each image will feature an overlay highlighting the focal area, which identifies the subject detected as the primary point of interest.

    Under the Original images, the uploaded images are displayed and each image has an overlay highlighting the focal area, which identifies the subject detected as the primary point of interest.
    Each image includes an editable overlay highlighting the detected focal point.

  5. If you want to edit the focal area in the images, select the image and then Edit focal area.

    One of the original image with a resize overlay is selected and the Edit focal area option is highlighted.
    Each image features an overlay marking the detected focal point, which you can adjust as needed.

    You can also use the Adjust Focal Points button in the upper-right corner to modify focal points for uploaded images.

  6. In the Edit focal point view, use the crop handles to adjust the size of the crop box, and drag it to the area of the image you want to emphasize. Select Back to exit the view and return to the gallery of uploaded images.

    The Edit Focal Point view is open, featuring an adjustable crop option. A list of uploaded images is available for selecting and adjusting the resize crop box.
    Fine-tune the resize crop box to make sure the focal point remains centered and the composition fits your desired dimensions.

    Use the image list displayed at the bottom of the page to quickly navigate between uploads and edit focal points for each image individually, ensuring accurate subject placement during resizing.

  7. In the Set layouts section, under Sizes and focal points, you can browse and select from the preset sizes for image resizing.

    The Set layouts section is open, and under the Sizes and focal points option, you have the option to browse and select from the preset sizes for image resizing.

  8. To add custom sizes, enter the desired width and height, then select the   icon. Each custom size you add will appear in the list of selected sizes for image resizing, with a checkbox that lets you easily select or deselect it as needed.

    In the Set Layouts section, under Sizes and Focal Points, you can add custom dimensions by specifying the width and height in pixels. Currently, a size of 1000 × 1000 pixels has been added.
    Along with presets, you can add custom dimensions by specifying the width and height in pixels to resize your image.

  9. When you are done specifying sizes for image resizing, a composition layout appears for each one. A dot indicates the position of the focal point within the final output image, and it is applied to all images that share the same size.

    The composition layout is displayed for each of the uploaded images and a pink dot indicates the focal point for the image.
    The layout view with a focal point marker ensures each image stays well-framed during resizing.

  10. To adjust the focal point for any of the added sizes, simply select and drag it to your desired position on the grid.

  11. To review the focal points for the final outputs, go to the Previews tab and use the image list at the bottom of the page to navigate between your uploads.

    The Previews tab is selected, showing a list of resized image previews.
    Use the preview function to view resized images with specified focal points and dimensions.

  12. If any uploaded images are too small or do not meet the required dimensions after resizing, the resulting empty areas will appear as transparent boxes. When the Apply GenExpand option is enabled, these empty spaces will be automatically filled using generative AI.

    In the Preview tab, images are displayed with specified focal points and dimensions, and the Preview with GenExpand option is highlighted.
    If resized images don’t meet the required dimensions, transparent areas will appear, which can be filled using AI-generated expanded content.

    Note
    • The Apply GenExpand option is enabled by default.
    • You can select Preview with GenExpand   to view how the output will look after GenExpand is applied. Please note that generating the preview may take a few seconds.
    The Apply GenExpand option is enabled so that if resized images don’t meet the required dimensions, any transparent areas can be filled using AI-generated expanded content.
