PNG / JPEG vs WebP

Side-by-side comparison, when-to-use-each guide, and instant conversion. Reviewed for 2026.

Quick answer: JPEG is best for photos (small file, lossy). PNG is best for graphics with sharp edges (lossless, supports transparency). WebP is the modern alternative — usually 25-35% smaller than equivalent JPEG/PNG, with both lossy and lossless modes, and now supported by all major browsers (since 2020).
