What is WebP?
A plain-English definition, and the tools that work with it.
WebP is a modern image format from Google that makes photos and graphics significantly smaller than JPG or PNG at similar quality. It's designed for the web to speed up page loads, and supports both lossy and lossless compression plus transparency.
- WebP typically saves 25–35% over JPG/PNG, so it's excellent for website performance.
- Support is now broad in browsers, but some older apps and offline editors still can't open it: hence the frequent need to convert it to JPG.
- It handles transparency (like PNG) and photos (like JPG), making it a versatile single choice for web images.

- JPG (JPEG)JPG (also written JPEG) is the most common photo format. It uses lossy compression to make photographs small by discarding detail your eye barely notices, which is why it's ideal for pictures but poor for sharp graphics, text or transparency.
- PNGPNG (Portable Network Graphics) is a lossless image format that supports transparency. Because it never degrades on save and keeps sharp edges, it's the go-to format for logos, icons, screenshots and any graphic with text or a transparent background.
- Image compressionImage compression reduces an image's file size. Lossy compression (JPG, WebP) discards detail your eye barely notices for big savings. Lossless compression (PNG) shrinks the file while keeping every pixel. The right kind depends on whether small size or perfect fidelity matters more.
