Upscale a batch with consistent settings

Use the batch workflow for a folder of listing images, presentation assets, or graphics that should follow one size rule.

Each file keeps its own aspect ratio and is enlarged only when it is below the target. The tool does not enlarge an image already at or above the selected longest-side size.

How to enlarge an image

  1. 1

    Add your images

    Select one or more supported image files.

  2. 2

    Review the target size

    The batch starts with the same 3000 px longest-side target for every image. Each file is still limited to a maximum 4× enlargement.

  3. 3

    Save the enlarged image

    Run the tool, preview the result, and download the PNG output.
