About the Formats

JPG (Joint Photographic Experts Group)

JPG (or JPEG) is the world's most widely used image format for photographs. Lossy compression achieves small file sizes at the cost of some image detail — a trade-off that works well for natural scenes and photographs where minor quality loss is imperceptible.

Compatibility: Universal — supported by every browser, OS, device, and image application on the planet.

WebP (Web Picture Format)

WebP is a modern image format developed by Google for the web. It delivers superior lossless and lossy compression compared to PNG and JPG — WebP images are typically 25–35% smaller than equivalent JPGs at the same visual quality — while also supporting transparency and animation.

Compatibility: Chrome, Firefox, Edge, Safari 14+, and most modern applications.
