Frequently Asked Questions

PNG (Portable Network Graphics):

  • Lossless compression format
  • Best for images with text, sharp edges, or transparency
  • Larger file sizes compared to lossy formats
  • Widely supported across all platforms and browsers

JPEG (Joint Photographic Experts Group):

  • Lossy compression format
  • Ideal for photographs and complex images with gradients
  • Smaller file sizes but may lose quality with high compression
  • No support for transparency
  • Universal support across all platforms

WebP:

  • Modern format developed by Google
  • Supports both lossy and lossless compression
  • Better compression than PNG and JPEG (25-35% smaller)
  • Supports transparency
  • Good browser support (except older Safari versions)

AVIF:

  • Newest format, developed by Alliance for Open Media
  • Excellent compression efficiency (smaller than WebP)
  • Supports HDR and wide color gamut
  • Limited browser support (Chrome, Firefox, Safari 16+)

Lossless Compression:

  • Preserves 100% of the original image quality
  • No data is lost during compression
  • Results in larger file sizes
  • Best for images requiring perfect quality (e.g., screenshots, logos)

Lossy Compression:

  • Reduces file size by removing some image data
  • Quality loss can be controlled (high, medium, low settings)
  • Great for web images where small quality loss is acceptable
  • Can significantly reduce file size (up to 90% in some cases)

Size Increases:

  • Converting from lossy (JPEG) to lossless (PNG) formats will increase size
  • Adding transparency to an image requires additional data
  • Converting from a modern format (WebP) to older formats may increase size

Size Decreases:

  • Modern formats (WebP, AVIF) use more efficient compression algorithms
  • Lossy compression can significantly reduce file size
  • Removing unnecessary metadata and color information can reduce size

Format Support by Browser:

  • PNG/JPEG: Supported by all browsers
  • WebP: Supported by all modern browsers (Chrome, Firefox, Safari 14+, Edge)
  • AVIF:
    • Chrome 85+ (full support)
    • Firefox 93+ (full support)
    • Safari 16+ (partial support)
    • Edge 95+ (full support)

Recommendations:

  • Use WebP for modern websites with a JPEG/PNG fallback
  • Consider AVIF for future-proofing and maximum compression
  • Always keep PNG/JPEG versions for maximum compatibility

Progressive (JPEG) or interlaced (PNG) loading is a technique that allows images to load gradually, showing a low-quality version first that progressively improves in quality.

Key Benefits:

  • Better user experience during slow connections
  • Faster initial page rendering
  • Visual feedback while the full image loads

Format Support:

  • JPEG: Supports progressive loading
  • PNG: Supports interlaced loading
  • WebP and AVIF: Do not support progressive/interlaced loading
