JPG to WebP Converter

xFormat.space converts JPG photos to WebP inside your browser, with an adjustable quality slider, so you can slim down web images without uploading them anywhere.

Runs in your browser — files never leave your device.

How it works

If you publish photos on a website or blog, WebP is a straightforward way to lighten your pages. Drop in your JPGs, choose a quality level and convert them in batch. The work runs on your own device and your originals stay untouched.

  1. 1

    Drop your JPG files onto the page.

  2. 2

    Select WebP as the output format and set the quality slider.

  3. 3

    Click Start Conversion, compare the file sizes in the results, and download.

Why people move photos from JPG to WebP

WebP is generally able to hit the same visual quality as JPG at a smaller file size, which helps page load times and bandwidth. The results list shows the new size of every file, so you can see what you actually saved instead of guessing, and savings vary by image.

Picking a quality setting

Start somewhere around 75 to 85% for photos and look at the result at full size. Go lower for thumbnails and backgrounds, higher for hero images and product shots where artifacts would be noticed. The slider runs from 10% to 100%, and the default is 92%, which favors fidelity over size.

Because you are going from one lossy format to another, avoid converting the same file repeatedly, and keep the original JPG as your master copy.

Compatibility check

All current major browsers display WebP, but encoding it relies on your browser. Recent Chrome, Edge and Firefox can export WebP; if a file does not come out as WebP in your browser, try one of those. Some older apps and upload forms still refuse WebP, so keep a JPG around for those.

Frequently asked questions

Is WebP smaller than JPG?

Often yes, at comparable visual quality, but the saving depends on the image. The results list shows the exact size of each converted file so you can check.

What quality should I use for JPG to WebP?

Around 75 to 85% is a good starting point for photos. Compare at full size and raise it if you notice artifacts.

Can I convert many JPGs to WebP at once?

Yes. Add as many JPGs as you need, convert them together, and use Download All.

Will my JPG files be uploaded?

No. The conversion happens in your browser. Nothing is uploaded and there is no sign-up or watermark.

Do all browsers and apps support WebP?

Current major browsers display it, but some older software and upload forms do not. Keep the original JPG for those cases.
