WebP vs PNG
WebP and PNG solve related needs, but they prioritize different strengths. WebP is a modern web image format offering efficient lossy or lossless compression and transparency. PNG is a lossless raster format valued for transparency, sharp edges and repeatable editing. This comparison explains the practical differences so you can choose according to your workflow rather than treating either option as universally better.
Quick Recommendation (Quick Winner)
WebP has the stronger fit for Typical file size: Very small.
PNG has the stronger fit for Ease of use: Very easy.
WebP has the stronger fit for Compression: Highly efficient.
Both options score equally across the relevant configured criteria, so the use case should decide.
