Compression Formats Explained

  • JPEG: Best for photographs. Lossy compression with excellent file size reduction. Quality 70-85% recommended for web.
  • PNG: Best for graphics, logos, screenshots with text. Lossless compression maintains perfect quality but larger files.
  • WebP: Modern format with superior compression. 25-35% smaller than JPEG/PNG with same quality. Supported in all modern browsers.

Tips for Best Results

  • Start at 80% quality: Sweet spot for most images — good quality with significant size reduction
  • Use WebP when possible: Best compression ratio and quality, supported in 95%+ of browsers
  • JPEG for photos: Natural images compress better with JPEG than PNG
  • PNG for text/graphics: Logos and screenshots with sharp edges look better as PNG
  • Test different quality levels: Sometimes 60% looks identical to 100% at fraction of file size
