JPG vs WebP
JPG (JPEG) is the standard format for photographs. It uses lossy compression, which discards fine detail the eye rarely notices to keep files small, and it has no transparency.
WebP is a web image format from Google that can be lossy or lossless and supports transparency and animation. Its lossy files are usually smaller than a JPG of similar quality. Every current major browser shows it, but some older editors, apps and upload forms still refuse it.
What changes when you convert JPG to WebP
- JPG has no transparency to begin with, so the WebP copy starts fully opaque; you can then edit it to add transparent areas.
- The WebP copy is usually noticeably smaller than the JPG, which helps page speed. Keep the original if you also need a copy for software that doesn't open WebP.
- Convert when the place you are sending the image needs WebP. WebP is best for images on websites, where smaller files load faster.
