JPG VS WEBP

JPG or JPEG, is the most common image format to store digital images in lossy compression. It can keep an image in quite small size, but the image quality gets perceptible loss. While, WebP is the image format that balances size and image quality very well, with both lossy and lossless compression applied, it makes image smaller but preserves quality.

JPG or JPEG is used everywhere on the Internet and can be opened in almost all web browsers, even can be previewed on basically all social media platforms. While, WebP is more preferred by website owners for SEO benefits, it can be opened in approx. 95% web browsers across the world, but a great part of open source image viewers still don’t support reading a WebP image.

A WebP image is 25%~35% smaller in size when comparing with a JPEG file at same SSIM index.

JPG or WebP, that’s depend on your need, no matter converting JPG to WebP or WebP to JPG, both can be done easily.
