JPG to WebP

This lesson is part of Web Developer Tools · All levels

Summary

Converting JPG to WebP converts lossy photos into a modern format that usually produces smaller files of equal visual quality. Since JPG has no transparency, no alpha needs to be maintained. Use a lossy mode with sufficient quality, then compare the results to the area of detail before replacing the entire site image.

Key points

WebP often produces 25-35% smaller files than JPEG at similar quality.
JPG doesn't have an alpha, so this conversion doesn't address transparency.
WebP's lossy mode is suitable for photos, while lossless for full detail
Too low quality can eliminate fine texture
Provide JPEG fallback for older browsers or applications
