About the JPG / JPEG & WebP Formats
JPG / JPEG (Joint Photographic Experts Group)
JPEG is a widely used lossy compression standard for digital images, particularly for those produced by digital photography. It achieves a balance between image quality and file size.
- Extremely high compatibility across all devices and browsers
- Small file sizes for photographic images
- Adjustable compression ratio
- Lossy compression degrades quality with repeated edits
- Does not support transparency (alpha channel)
- Does not support animation
WebP (Web Picture Format)
WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. It allows webmasters to create smaller, richer images.
- Typically 25-34% smaller file sizes compared to PNG and JPEG at equivalent quality
- Supports both lossy and lossless compression
- Supports transparency and animation
- Slightly higher CPU overhead for compression/decompression
- Older browsers (like IE11 or older Safari versions) do not support it
