How to convert JPG to WebP
- Add your JPG or JPEG images with Select files or by dragging them onto the page.
- Adjust the Quality slider. Around 75–85 is a good balance for website images.
- Click Convert to encode each photo as WebP on your device.
- Download the WebP files one by one or together as a ZIP.
Why WebP is popular for websites
WebP is an image format developed by Google for the web. At comparable visual quality, lossy WebP files are typically around a quarter to a third smaller than JPEGs, according to Google's own comparisons. Smaller images mean faster pages, less mobile data and better scores on loading metrics such as Largest Contentful Paint.
Every current major browser, including Safari, can display WebP, so it is a safe choice for most websites.
Because WebP also supports transparency and animation, many sites use it as a single format for photos, graphics and simple animations alike.
Browser requirements for creating WebP
This converter uses the WebP encoder built into your browser. Chrome, Edge and Firefox can create WebP files; Safari can display them but cannot create them, so the tool will tell you to switch browsers if you open it in Safari. Nothing is uploaded either way.
Tips for the best results
Converting a JPG to WebP is a second round of lossy compression, so start from the highest-quality original you have and keep it as your master copy. Some email clients and older desktop programs still do not open WebP; for those audiences keep a JPG version, or convert back later with WebP to JPG.
Frequently asked questions
Is WebP supported everywhere?
All modern browsers display WebP. Some older software, email clients and upload portals still reject it, so keep JPG copies for those.
Why doesn't the converter work in Safari?
Safari can show WebP images but its canvas cannot encode them. Use Chrome, Edge or Firefox to create WebP files.
What quality should I choose?
Start at 80 and compare. Hero images may need 85, while thumbnails often look fine at 70.
Does the WebP file keep EXIF metadata?
No. Camera and location data are not copied, which also saves a few kilobytes per image.
How many images can I convert at once?
Up to 30 per batch, downloaded together as a ZIP.
