JPG to WebP Converter
Convert JPG photos to WebP and cut their size without visible loss. Ideal for blog images, product photos and anything you serve on a website, and nothing is uploaded.
Faster pages with WebP
Images often account for most of a page's weight. WebP typically saves 25 to 35 percent compared with JPG at the same visual quality, so pages download faster, especially on mobile networks. Faster pages help visitors stay and are a factor in search ranking through Core Web Vitals.
Swap your hero image and gallery photos first, since the largest image on screen decides your Largest Contentful Paint time.
Browser support and fallbacks
Every current version of Chrome, Edge, Firefox, Safari and Opera displays WebP. If you still have to support very old browsers or email clients, keep the JPG and offer WebP through a picture element so each visitor gets a format they can read.
Many content management systems and image CDNs also generate WebP automatically, but converting the source yourself gives you full control.
Choosing the quality
Start with quality 80. Compare the result at full size on a good screen; if banding or blur shows up in skies and skin, move to 85 or 90. Because JPG is already lossy, converting adds another compression step, so avoid very low values.
Keep the original JPG as your master copy. The WebP is for publishing, not for archiving or further editing.
Frequently asked questions
How much smaller is WebP than JPG?
Usually 25 to 35 percent at similar quality, sometimes more.
Is WebP lossless here?
No. The tool uses lossy WebP controlled by the quality slider.
Does WebP work in Safari?
Yes, in current versions on macOS and iOS.
Should I delete my JPG files afterwards?
No, keep them as masters.
Will converting hurt image quality?
At quality 80 to 90 most people cannot tell the difference. Because the source JPG is already compressed, avoid very low settings that would add visible artifacts.
Can I convert a whole product catalog at once?
Yes. Add many JPG files together, let them process one by one, and download the WebP results in a single ZIP, keeping the original file names.
