What Is JPG?
JPG (also called JPEG) is one of the oldest and most widely supported image formats.
Nearly every operating system, browser, image editor, printer, camera, and website supports JPG, making it the safest choice when compatibility is your priority.
Image Quality
Both formats can produce excellent-looking images.
For most people, there is little visible difference between a properly compressed WebP image and a JPG image.
However, WebP usually achieves similar visual quality using a smaller file size.

File Size
One of WebP’s biggest advantages is its efficient compression.
Compared to JPG, WebP images are often 20–35% smaller while maintaining similar visual quality.
Smaller images mean:
- Faster websites
- Less bandwidth usage
- Lower storage requirements
- Faster downloads

Website Performance
Since WebP images are smaller, websites load faster.
Faster loading pages improve the user experience and can contribute to better search engine performance.
For blogs, online stores, and business websites, WebP is usually the preferred format.

Compatibility
JPG has been around since the early 1990s.
Almost every application, operating system, website, printer, and image editor supports JPG without any additional software.
Although WebP support has improved dramatically, some older applications still don’t recognize it.
