BPG Strengths
- Exceptional compression efficiency that vastly outperforms standard JPEG at similar quality levels
- Supports high bit depths (up to 14 bits per channel), lossless compression, and alpha channel transparency within a single format
- The official JavaScript decoder allows the format to be rendered on standard HTML5 canvas elements
- HEVC (H.265) patent encumbrance prevented native adoption in major web browsers
- Superseded conceptually by the open, royalty-free AVIF format
- Encoding BPG files is computationally intensive and requires specialized command-line tools
WebP Strengths
- Superior lossy compression — 25–35% smaller than JPEG at equivalent quality
- Supports both animation and full alpha transparency
- Lossless mode available with smaller file sizes than PNG
- Slower encoding than JPEG, especially for lossless
- Not supported in Internet Explorer or very old browsers
When to choose which format
- High-Efficiency Image Archival
- Bandwidth-Constrained Environments (via JS decoder)
- Websites
- Ecommerce
- Mobile Apps
- CMS Images
