Create a WebP version of a JPG for a modern web workflow. Choose the output quality and compare the result; the final file size depends on the source image and settings. The tool decodes the JPG and creates a real WebP file while preserving the original pixel dimensions. Review the preview before downloading; the source file stays unchanged and the complete conversion runs locally in your browser.

JPG compared with WebP
JPG is a widely compatible, lossy photo format without transparency.
WebP is a web-focused raster format with efficient lossy compression and alpha transparency.
Quality, compression and transparency
WebP uses adjustable lossy compression in this converter. Higher quality usually retains more detail and increases file size. Transparent pixels decoded from JPG can remain transparent through the alpha channel, and the original pixel dimensions are preserved.
