WebP vs JPG
Compare the classic photo format with a modern web image format.
JPG is still the most compatible photo format in the world, but WebP is often a better delivery format for modern websites. Both can use lossy compression for photos, but WebP usually creates smaller files at similar visual quality. The practical workflow is simple: keep JPG originals when you need compatibility, and use WebP exports when page speed and transfer size matter.
Choose WebP when
- You are optimizing website photos, landing pages, or product images.
- You want smaller files without changing the visible photo too much.
- Your audience uses modern browsers and CMS platforms.
Choose JPG when
- You need the safest format for old apps or upload forms.
- The file will be shared by email or edited in legacy software.
- You want a simple universal backup of a photo.
Photo compression
JPG has been excellent for photos for decades, but repeated saves can add artifacts. WebP uses newer compression and often reduces file size further while keeping photos visually close to the JPG source.
Transparency
JPG does not support transparency. WebP can, but converting a JPG to WebP will not create transparency because the source file has no alpha channel.
Compatibility
JPG wins in old software and broad offline compatibility. WebP wins for modern web delivery, especially when many images load on the same page.
Use JPG for universal compatibility and source backups. Use WebP for faster modern websites.
