Use JPG to WebP to prepare photographs for a website that accepts WebP. Compare the actual result with your original before replacing an image; the smallest suitable format depends on the picture.
Example: when to use this tool
You are preparing photos for a website that accepts WebP. Convert one representative photo and compare its byte size and appearance before replacing the JPG.
Quality and output
Default WebP output uses lossy encoding. PNG transparency can be retained, but RGB pixels can change. Do not assume a fixed percentage reduction or lossless output.
How to use
- Upload a valid JPG file.
- Run the conversion to WEBP.
- Download the result and check it before replacing your original.
Before you download
Download and compare byte sizes before replacing the original. Already optimized files can stay the same size or grow; compression is not a guaranteed reduction percentage.
