How it works

  1. 01

    Prepare your source

    Choose a supported source image, or begin with the text template when the tool provides one.

  2. 02

    Adjust the result

    Upload a local image to preview cover, contain, positioning, repeat and an overlay. Set the published asset path separately; the generated CSS uses that path and does not embed or upload the source file.

  3. 03

    Review and download

    Inspect the complete preview and output settings. Download the finished asset, keeping the original available for comparison.

About this tool

Create with CSS Background Generator

Tips for better results

  • The local preview uses the file you selected. Your website needs a hosted asset or a path in your project. Upload or copy the image there and ensure the CSS path resolves from your stylesheet.
  • Keep the original file until the result has been checked.
  • Inspect small text and fine edges at the intended display size.
  • Image processing happens in your browser. Download the result before closing the tab. The tool does not overwrite your original file.
