Switching JPG photos to WEBP is one of the simplest ways to make a website load faster without any visible drop in quality. The JPG to WEBP tool re-encodes your photos into WEBP at the quality level you choose, shaving bytes off every image so your pages feel snappier on phones and slow connections alike.
How to use the JPG to WEBP tool
- Select your JPG image.
- Adjust the quality slider.
- Click Convert.
- Download the WEBP file.
The easy win for performance
Images make up the bulk of most web pages by size, so compressing them pays off more than almost any other optimisation. WEBP was designed specifically for the web and squeezes photographs into noticeably smaller files than JPG at the same perceived quality. For a photo gallery, a blog or an online store, converting the whole image library to WEBP can dramatically cut load times and the bandwidth you serve.
Tips for the best output
- A quality of 75–85% is usually indistinguishable from the original JPG.
- Compare before and after on a detailed photo to confirm you are happy.
- Keep the original JPG as a master in case you need to re-export later.
- Serve WEBP with a fallback for very old browsers that still lack support.
The conversion happens locally on a canvas, so nothing is uploaded and there is no cap on how many photos you convert. It is a free, private way to modernise an entire image set.
