JPG to WebP is the easiest win in web performance. The same photo saved as WebP is typically 25 to 35% lighter at a similar visual quality, and every modern browser displays it. Convert one photo or a whole folder of JPGs at once.
How to convert JPG to WebP
- Drop your JPG files in the box above, or click to pick them. You can add as many as you like.
- WebP is already selected as the output format. Switch on other formats if you want them too.
- Optional: open Advanced Settings to resize by percentage, width or height, and add more sizes.
- Click Start Conversion, then download each file or all of them at once. Nothing is uploaded: the conversion runs in your browser.
Why convert JPG to WebP?
Google recommends serving next-gen formats, and WebP is the most widely supported one. Smaller photos load faster on mobile, improve your Largest Contentful Paint and reduce hosting bandwidth. Keep the original JPGs as a fallback if you support very old browsers.
Frequently asked questions
Will my photos lose quality?
JPG and WebP are both lossy formats. The converter uses a high quality setting, so differences are very hard to see, while the file gets noticeably smaller.
Can I convert many JPGs at once?
Yes. Drop as many JPG files as you want; they are processed one after another and you can download them all together.
Are my photos uploaded?
No. The conversion runs entirely in your browser, on your device. Your images are never uploaded to a server, so this works for private and confidential files too.
