Choosing the right image format matters more than most people think. The difference between JPG, PNG, and WebP can mean a 2x-5x difference in file size — which directly affects website speed, email deliverability, and storage costs.
What Is JPG (JPEG)?
JPG uses lossy compression — it removes color data to create smaller files. At quality 80–95%, the visual difference from the original is nearly invisible.
- Pros: Universal support, small files, great for photos
- Cons: No transparency, quality degrades with each re-save, not ideal for text/logos
- Best for: Photography, social media posts, blog images
What Is PNG?
PNG uses lossless compression — every pixel is preserved exactly. PNG supports transparency (alpha channel).
- Pros: Lossless quality, transparency support, sharp edges preserved
- Cons: Larger file sizes than JPG, no animation (use APNG or GIF)
- Best for: Logos, screenshots, graphics with text, images needing transparency
What Is WebP?
WebP is Google's modern format that supports both lossy and lossless compression, transparency, and animation — all in one format.
- Pros: 25–35% smaller than JPG at same quality, transparency, animation, universal browser support
- Cons: Some older software doesn't support it, slightly more CPU-intensive to encode
- Best for: Web images, email, any use where file size matters
