Website images should be optimized for crisp display across all devices. Here's what you need to know:

Key Requirements:

  • Maximum file size: 20 MB (recommended: under 500 KB for fast loading)
  • Minimum width: 1,500 pixels (2,500 pixels ideal)
  • File types: JPG, PNG, GIF
  • Color mode: RGB

Image Size Optimization:

  • Squarespace creates 7 responsive versions (100px to 2,500px wide)
  • Upload images larger than your maximum display size
  • Keep total page size under 5 MB for optimal loading
  • Images under 1,500px wide may appear blurry

Best Practices:

  • Use PNG format for images with text or transparent backgrounds
  • Maintain consistent aspect ratios in galleries (all landscape or all portrait)
  • Add alt text for accessibility and SEO
  • Overlay text instead of embedding it in images
  • Consider mobile cropping when using banner images

Troubleshooting Common Issues:

  • Blurry images: Check minimum width requirements
  • Color distortion: Verify RGB color mode
  • Cropping problems: Use focal points and proper aspect ratios
  • Resolution changes: Follow size recommendations for consistent display

Special Considerations:

  • Logos: Different requirements for website vs. email use
  • Banners: Will crop differently on mobile devices
  • Galleries: Match aspect ratios for best appearance
  • Transparent backgrounds: Use PNG format

For Acuity Scheduling:

  • 600px x 600px maximum for calendar images
  • 600px x 120px maximum for logos
  • Square images (1:1 ratio) recommended
  • Lower file size limits than regular site images

Remember to keep original files on your computer, as downloaded versions may have reduced quality.
