WebP vs. JPEG vs. PNG: WebP is 25–35% smaller than JPEG at same quality. PNG is lossless but produces large files. WebP is supported by all modern browsers.

When to use which image format
Choosing the right format for each photo type saves asset size without visible quality loss:
- JPEG:Best for photographs with gradients and many colors. Quality 80–85 produces excellent results.
- PNG:Best for screenshots, transparency, and graphics with sharp edges. Preserves every pixel.
- WebP:Best for everything on the web. Supports transparency like PNG with optimization like JPEG.
- Batch optimization:Compress 10+ images at once. Drop a folder, click one button, download a ZIP archive.
