About JPG to WebP
WebP was designed by Google specifically for the web, and it does a measurably better job than JPEG at the same perceived quality — typically 25–35% smaller for photographs. It also supports transparency and animation, which JPEG does not.
Browser support is no longer a concern: every current version of Chrome, Firefox, Safari and Edge renders WebP, and has done for years. For most websites, serving WebP instead of JPEG is one of the cheapest performance improvements available, and it directly affects Core Web Vitals scores like Largest Contentful Paint.
This converter re-encodes each JPEG as WebP in the browser and reports the saving per file, so you can verify the benefit on your own images rather than trusting a general statistic.

Where WebP helps most
- Website images — smaller files mean faster pages and better search rankings.
- Image-heavy pages such as galleries, product grids and blog archives, where savings multiply.
- Mobile visitors on limited data plans.
- Anywhere you would otherwise need a transparent PNG of a photograph — WebP does both, at a fraction of PNG's size.
When to stay with JPEG
Some contexts still expect JPEG specifically: older printing workflows, certain camera and scanner software, and a handful of upload forms that validate by extension. If a system rejects your WebP file, convert it back with the WebP to JPG tool.
It is also worth remembering that converting an existing JPEG to WebP re-encodes an already lossy file. The saving is real, but for the very best result, produce WebP from the original uncompressed source when you have one.
