Frequently Asked Questions
For web images: 70–85% is the sweet spot — significant size reduction with imperceptible quality loss. For high-quality prints: 85–95%. For thumbnails or previews: 50–70%. The exact ideal quality depends on the image content — photos with lots of detail and color variation compress well, while flat graphics may show artifacts at lower quality settings.
WebP typically achieves 25–35% smaller file sizes than JPEG at equivalent visual quality. WebP also supports transparency (unlike JPEG). The downside is slightly lower compatibility — WebP is supported by all modern browsers (Chrome, Firefox, Safari 14+, Edge) but not by some older software. For web use, WebP is generally the better choice.
