About the JPG Format
JPEG is the most widely used image format on the internet. It uses lossy compression, which means it reduces file size by discarding some image data that the human eye is unlikely to notice. This makes JPEG ideal for photographs and complex images with many color variations. However, each time you save a JPEG, it loses a small amount of quality — this is known as generation loss. JPEG does not support transparency or animation.
The JPEG format was created in 1992 by the Joint Photographic Experts Group. It quickly became the standard for digital photography and web images due to its efficient compression and universal browser support.
✅ Advantages
- Extremely small file sizes for photos
- Universal support across all devices and browsers
- Adjustable compression quality
- Ideal for photographs and complex images
❌ Disadvantages
- Lossy compression — quality degrades with each save
- No transparency support
- No animation support
- Not ideal for text, line art, or sharp edges
About the AVIF Format
AVIF is the newest and most advanced image format available today, based on the AV1 video codec developed by the Alliance for Open Media. It offers significantly better compression than both JPEG and WebP — producing files up to 50% smaller than JPEG at the same visual quality. AVIF supports HDR (High Dynamic Range), wide color gamuts, transparency, and animation. It represents the cutting edge of image compression technology.
AVIF was first released in 2019, based on the royalty-free AV1 video codec. It was developed by the Alliance for Open Media, which includes major tech companies like Google, Apple, Microsoft, Mozilla, Netflix, and Amazon. Browser support has been rapidly expanding since 2020.
