How to Re-Compress WebP Files for Peak Performance

Not all WebP files are optimized. Many automated CMS plugins and export tools save WebP at 100% quality or lossless mode by default, creating unnecessarily large 2MB–5MB files.

By applying custom quantization between 75% and 82%, you can safely remove invisible high-frequency data, cutting file size by 50% to 75% without any perceptible drop in visual quality on retina screens.
