When Do You Need to Change Background Colour?

  • Product photography for Amazon, Etsy, or Shopify — requires white (#FFFFFF) backgrounds
  • Passport and ID photos — require plain white or off-white backgrounds
  • LinkedIn and professional headshots — clean grey or white backgrounds look most professional
  • Marketing assets — match your brand colour palette for consistency
  • Social media images — change backgrounds to match campaign themes

How to Change Background Colour at imgresizr.com

Upload your photo to imgresizr.com. Use the Background Colour tool to select your target colour. You can choose from preset colours (white, grey, black, blue, green) or enter a custom hex code for precise brand colour matching. The tool automatically detects the subject and replaces the background. For best results, photos with a clear subject and relatively uniform original background work best. After applying the colour change, use the Enhance tool to adjust the subject's exposure if the new background changes the apparent brightness. Download as PNG to preserve transparency edges or JPG for the filled colour version.

Tips for Background Colour Changes

  • Start with a photo where the subject is well-separated from the background
  • Simple, single-colour backgrounds are easiest to replace cleanly
  • Hair and wispy edges may need extra attention — use the refine edge option if available
  • Always check the edges at 100% zoom before downloading
