JPG vs. WebP
The universal standard vs. a modern format built for smaller web files.
Image Tools
WebP is a newer format designed specifically to beat JPG's compression efficiency at equivalent visual quality, while also supporting transparency and animation, which JPG can't do at all. JPG's advantage is near-universal compatibility, including in older software WebP support can still be inconsistent in.
JPG
Best for
- Maximum compatibility with older software, email clients, and some print workflows
- Situations where you can't control or guarantee the viewer's app supports WebP
Trade-offs
- Larger files than WebP at equivalent visual quality
- No transparency or animation support
WebP
Best for
- Web images, where smaller files mean faster page loads
- Modern browsers and platforms — support is now effectively universal in current browsers
Trade-offs
- Some older desktop software and email clients still don't display it
- Slightly less predictable behavior across very old or niche tools than JPG's decades of universal support
| Dimension | JPG | WebP |
|---|---|---|
| Compression efficiency | Baseline | Typically 25-35% smaller at equivalent quality |
| Transparency | Not supported | Supported |
| Compatibility | Universal, including old software | Universal in modern browsers; inconsistent in some older/niche apps |
Verdict
For web use, WebP is the better default today — smaller files, same or better quality, and browser support is no longer a real concern. Keep JPG for content that has to work in older or unpredictable software outside the browser.
