Expand an image: frequently asked questions

Does the original image change?

The original region is copied without resizing after orientation correction and conversion to 8-bit sRGB RGBA. Its pixels remain unchanged in that format; the original file metadata and higher bit depth are not preserved.

How is the canvas expanded?

Use an aspect ratio layout, expand from the original dimensions or enter a custom canvas. Drag the image or set its position in pixels. The original stays fully inside the canvas and is not resized.

Do I need to sign in?

Sign in before uploading a reference image or running image analysis. If you select a file as a visitor, its name can be kept for reselection after sign-in; the file is not uploaded automatically.

Which files can I upload?

Use JPG, PNG or WEBP images. The uploader checks file type, size and the current image-count limit before sending files. Any failed check is shown in the workspace.

When do I confirm the credit cost?

Get a quote after adding your image and settings. Review the displayed credits, then choose Confirm and generate. A new generation requires its own quote and confirmation.

Are the example images actual results from this tool?

The labeled scene illustrations show possible directions; they are not actual outputs from the tool. Your uploaded reference and task results are displayed separately. Check the output before using it.
