Image weight is one of the most common reasons a website feels slow. Converting JPG photos to WebP is a simple fix: WebP files are often 25 to 35 percent smaller than JPG at a similar visual quality, which can help your page load faster and improve Core Web Vitals such as Largest Contentful Paint.
Convert JPG to WebP
Add your JPG files, check the settings and download them as WebP. Batch conversion, no sign-up and no watermark.
Why website owners switch to WebP
Search engines care about speed, and images are usually the heaviest part of a page. Shrinking them reduces download time on mobile connections, saves bandwidth and can lift user experience. WebP is supported by all modern browsers, and WordPress lets you upload WebP files to the media library, so it fits easily into most sites.
Convert and prepare your images
- Add JPG files with drag and drop or “Choose files”.
- Select WebP under “Convert to”.
- Set “Quality” to around 80 to 85 for photos. Set “Max width (optional)” to the largest size your layout actually displays.
- Download the WebP files or use “Download all (ZIP)”, then upload them to your site.
A practical workflow for faster pages
- Resize first. A 4000 pixel photo shown at 1200 pixels wastes bytes, so set the width before anything else.
- Test quality values. Convert one image at 75, 80 and 85, compare them, and use the lowest that still looks clean.
- Keep the original JPG as a backup in case you need another export later.
- Use descriptive file names such as red-ceramic-teapot.webp rather than IMG_2048.webp, which also helps image search.
- Add alt text, width and height attributes, and lazy loading for images below the fold.

Where JPG is still the better choice
WebP is not required everywhere. Email attachments, print shops, older desktop software and some marketplace uploads still ask for JPG. Keep a JPG copy for those cases, and publish the WebP version on your own pages. If you need to go back, WebP to JPG converts the files again.
Frequent issues
The WebP looks softer than the JPG
Raise the quality value a few points. Compression that looks fine on a landscape can show on faces and text.
The saving is tiny
Images that were already heavily compressed, or very small thumbnails, have little left to remove. Resizing with “Max width (optional)” usually helps more.
A platform rejected the WebP
Some services still accept only JPG or PNG. Upload the original JPG there.
Private and free
Files are converted in your browser, not uploaded. You get unlimited normal use, no registration and no watermark.
How much smaller is WebP than JPG?
Reductions of roughly 25 to 35 percent are common at similar visual quality, although the result depends on the picture.
Will WebP improve my SEO?
Faster pages can improve user experience and speed metrics, which search engines consider. WebP alone is not a ranking guarantee.
Can I upload WebP to WordPress?
Yes. WordPress supports WebP uploads in the media library.
Do all browsers display WebP?
All modern browsers do. Only very old browsers lack support.
What quality should I use?
Start at 80 to 85 for photos and compare. Lower values make smaller files but can show artifacts.
