    Canvas Fill: how it works

    Expand an image onto a larger canvas with a solid color fill.

    1. Choose output canvas dimensions and a fill color.
    2. The image is centered and the extra canvas is filled locally; no generative model is included.

    Privacy and output

    Processing runs in your browser. The tool reports the output size and gives you a direct download link. Check the result before using it in another app or form.

    Frequently asked questions

    Are files uploaded to Utilix?

    No. These image actions run locally in your browser. HEIC and PDF tools load processing libraries from public CDNs; file contents are still processed locally.

    Will every conversion make a smaller file?

    No. Output size depends on image details, dimensions, format, and quality. The result reports the actual size and ratio.
