Direct Answer • AEO Quick Summary

Why should I compress WebP files if they are already an optimized format?

Many export tools (such as Photoshop plugins or CMS auto-exporters) save WebP files at 100% quality or uncompressed lossless presets, leaving substantial bloat. Re-compressing WebP files with perceptual intra-frame prediction between 75% and 82% quality reduces file weight by an additional 30% to 50% without visible degradation, significantly accelerating Largest Contentful Paint (LCP).

Key Takeaways

  • WebP uses VP8 keyframe predictive coding to outperform JPEG by 25%–34%.
  • Re-compressing default CMS WebP exports frequently saves 30%–50% extra bandwidth.
  • Full alpha channel transparency and lossless modes are completely supported.
  • Supported by over 97% of all active desktop and mobile web browsers.
