Quick answer: To convert JPG to WebP, add the JPG files, keep 85 percent quality (or adjust it) and press Convert to WebP. WebP is typically 25 to 35 percent smaller than JPG at the same visual quality. Chrome, Edge and Firefox can save WebP; Safari cannot. Nothing is uploaded.
WebP holds the same photo in fewer bytes than JPG, which makes web pages and shops load faster. Convert a batch of JPGs here and pick the quality yourself.

How to convert JPG to WebP
- Choose one or more JPG files.
- Keep 85 percent quality, or lower it for smaller files.
- Press Convert to WebP.
- Download the WebP images, as a ZIP if there are several.
What you gain, what to watch
- Smaller files: at the same visual quality WebP is usually a quarter to a third smaller than JPG, more at lower quality settings.
- Every current browser shows it, including Safari on iPhone and Mac.
- Not everything accepts it: some email clients, older photo apps, print services and upload forms still want JPG. Keep your JPG originals.
Choosing the quality
Converting from JPG decodes the photo and encodes it again, so it cannot get better than the JPG was. 85 percent keeps it visually identical; 75 to 80 percent is a good balance for websites; below 70 percent, fine textures such as hair and foliage start to smear. To also cap the dimensions for a website, use Optimize images for web.
Browser note
Saving WebP needs Chrome, Edge or Firefox. Safari can display WebP but cannot create it, so in Safari the page saves JPG and tells you. The conversion runs on your device either way. Going the other way? Use WebP to JPG.

Frequently asked questions
Is WebP better than JPG?
For websites, usually: it is smaller at the same quality. For sharing with people and apps that may not open WebP, JPG is still the safer choice.
Does converting JPG to WebP lose quality?
Slightly, because the photo is re-encoded. At 85 percent it is not visible.
Can I convert many JPGs at once?
Yes. Add them all and download the WebP files as a ZIP.
Why did Safari give me a JPG?
Safari cannot write WebP files. Open the page in Chrome, Edge or Firefox to convert.
