| Format | First Major Release | Main Goal | Compression Type | Typical Quality vs JPEG | Transparency | Animation | Common Uses | Strengths | Weaknesses |
|---|---|---|---|---|---|---|---|---|---|
| JPEG / JFIF | 1992 | Smaller photo files | Lossy | Baseline standard | No | No | Photos, cameras, websites | Universal compatibility, fast | Visible artifacts at high compression |
| WebP | 2010 | Better web compression | Lossy + Lossless | Usually better than JPEG | Yes | Yes | Websites, apps | Smaller files, supports transparency | Older software/device support issues |
| HEIF | 2015 | Efficient modern photo storage | Usually HEVC-based | Better than JPEG | Yes | Limited | iPhones, modern phones | Excellent quality-to-size ratio | Compatibility/licensing issues |
| AVIF | 2019 | Maximum efficiency | Lossy + Lossless | Often best of all | Yes | Yes | Modern web/media | Extremely small files with high quality | Slower encoding, less universal support |
Rough “Evolution” Path
BMP/RAW
↓
JPEG/JFIF (1992)
↓
WebP (2010)
↓
HEIF (2015)
↓
AVIF (2019)
Simple Mental Model
JPEG = old reliable standard everybody supports
WebP = Google’s web-focused upgrade
HEIF = phone/camera efficiency format
AVIF = newest ultra-efficient compression king
File Size Example (Approximate)
Same image quality:
| Format | Approx File Size |
|---|---|
| JPEG | 5 MB |
| WebP | 3.5 MB |
| HEIF | 2.8–3.5 MB |
| AVIF | 2–3 MB |
(Real results vary by image type.)
Why JPEG Still Survives
Even though newer formats are technically better:
every device supports JPEG
printers understand it
old software works with it
cameras standardized around it decades ago
That kind of compatibility creates enormous inertia.
