What is JPG to WebP?
JPG to WebP re-encodes JPEG photos as WebP, which is often 25–35% smaller at the same visual quality and is shown by every current browser. It's the quickest win for PageSpeed's 'serve images in next-gen formats' advice, and the exact size change is shown after each conversion.
Key features
- WebP quality control (80 is a good start)
- Upright output using the camera orientation
- Optional resize
- Before/after format, dimensions, file size and % change
- Output decoded again and checked before download
- Runs in your browser — nothing is uploaded
Popular uses

Supported formats
Input: JPG, JPEG, JFIF. Output: WebP.
Troubleshooting
- The WebP isn't much smaller Photos already saved at low JPG quality have little left to remove. Lower the WebP quality slightly or resize.
- An old program won't open the WebP Keep the JPG for that program; WebP is meant for the web.
- The page says the image is too large for this device Very large pictures have to fit in your browser's memory. Close other tabs or use a computer.
- Need a different format? Open the Image Converter — it reads 10 formats and writes 7.
