Why Convert JPG to WebP?
JPG to WebP conversion re-saves a JPG image in Google's WebP format, which usually produces a noticeably smaller file at similar visual quality. Smaller images load faster, which helps page speed, Core Web Vitals and user experience. WebP is supported by all current major browsers, including Chrome, Edge, Firefox and Safari.
Images are often the heaviest part of a web page. A hero banner, a few product photos and a blog header can easily add several megabytes, and that is what makes pages slow on mobile data. WebP was created by Google to fix exactly this problem. According to Google's published comparisons, lossy WebP files are about 25–34% smaller than JPEG files at an equivalent quality index. Your own savings will vary with the image, but photos with smooth gradients and large flat areas tend to shrink the most.
Smaller images mean:
- Faster Largest Contentful Paint (LCP). On most pages the biggest element is an image, so a lighter file directly improves one of Google's Core Web Vitals.
- Lower bandwidth use for you and your visitors, which matters on slow or metered connections.
- Better mobile experience, where every extra kilobyte is felt.
- More room in storage and backups if you host thousands of images.
Be honest about the trade-off: converting an existing JPG to WebP re-compresses the image, so for the best quality keep your original file when possible and avoid converting the same image back and forth. At 75–85% quality the difference is rarely visible on screen.

Which Image Tool Should I Use?
How to Convert JPG to WebP
Add your JPG images
Drag and drop files, click browse, or press Ctrl+V to paste. You can add up to 50 files at 100 MB each.
Choose a quality level
Open Settings and move the Quality slider. Start with 80%. Go lower (around 70–75%) for thumbnails and backgrounds, or higher (85–90%) for hero images and product photos where detail matters.
Convert and download
Click Convert to WebP, then save the files one by one or use Download to get a ZIP.
How to Use WebP Images on Your Website
WordPress
Upload the WebP files to your Media Library like any other image. WordPress supports WebP uploads in current versions. Replace the old JPGs in your posts or set the new files as featured images.
Plain HTML with a safe fallback
If you want a fallback for very old browsers, use the picture element:
<picture>
<source srcset="photo.webp" type="image/webp">
<img decoding="async" src="photo.jpg" alt="Describe the image here" width="1200" height="800" title="JPG to WEBP Converter 2">
</picture>
Do these too
- Keep descriptive file names (red-running-shoes.webp, not IMG_4021.webp).
- Always write meaningful alt text.
- Set width and height attributes to prevent layout shift.
- Do not lazy-load the main above-the-fold image. Lazy-load the rest.
- Resize oversized photos before converting, since dimensions matter as much as format.
Where JPG is still the better choice
Email attachments, print workflows, older desktop software and some social or marketplace uploads still expect JPG. Keep your original JPGs for those uses.
Frequently Asked Questions
What is the best way to convert JPG to WebP?
Use a converter that lets you control quality, such as Teasoft's JPG to WebP tool. Add your images, set the quality (80% is a good start), click Convert to WebP and download the files or a ZIP.
Is WebP better than JPG?
For websites, usually yes. WebP files are typically smaller than JPG at similar visual quality, so pages load faster. JPG is still more universally supported in older software, email and print.
How much smaller is WebP than JPG?
Google reports that lossy WebP is about 25–34% smaller than comparable JPEG images. Actual savings depend on the image and the quality setting you choose.
What quality should I use for WebP?
For most website photos, 75–85% gives a good balance of size and sharpness. The tool defaults to 80%.
Does converting JPG to WebP lose quality?
Slightly, because the image is re-compressed. At 75–85% quality the difference is usually not visible. For best results, convert from the original JPG and avoid repeated conversions.
Will WebP improve my SEO?
WebP does not rank pages by itself, but smaller images improve page speed and Core Web Vitals such as Largest Contentful Paint, which are part of Google's page experience signals and affect how users experience your site.
Do all browsers support WebP?
All current major browsers support WebP, including Chrome, Edge, Firefox, Opera and Safari. Very old browsers may not, which is why some sites use a picture element with a JPG fallback.
Can I use WebP in WordPress?
Yes. Current versions of WordPress accept WebP uploads, so you can add the converted files to your Media Library and use them in posts and pages.
Can I convert many JPG files to WebP at once?
Yes. You can add up to 50 JPG files in one batch, each up to 100 MB, and download all the results as a ZIP.
