Frequently asked questions
How much smaller is WebP than JPG?
Typically 25 to 35 percent at similar visual quality. The exact saving depends on the image: smooth photos shrink more than ones with fine texture.
Will converting JPG to WebP hurt image quality?
A little, in principle, because both formats discard detail. At normal viewing size it is rarely noticeable. Keep the original JPG so you can redo the conversion if you need to.
Do I still need JPG on my website?
For browsers, no, since every current one displays WebP. Keep JPG for email, social uploads, print services and other places outside the browser that may not read WebP.
Does using WebP help SEO?
Indirectly. Smaller images make pages load faster, and page speed is one of many ranking factors. It will not move a page up the rankings on its own.
Are my JPG files uploaded anywhere?
No. The conversion runs in your browser using WebAssembly, so your JPG files stay on your device. There is no signup, no watermark and no cost, and you can convert a whole batch and download it as a zip.
About JPG to WebP
JPG to WebP is the classic website speed-up. Performance audits such as Google's PageSpeed Insights have long recommended serving photos in a newer format, and WebP is the easy fix: at similar visual quality it is typically 25 to 35 percent smaller. On a page with a dozen photos that adds up to real time saved, which helps visitors and is one of many signals search engines consider.

Support is no longer a barrier. WebP works in every current version of Chrome, Edge, Firefox and Safari, and has done so since Safari 14 in 2020. It also supports transparency, though a photo that started as a JPG has none.
Both formats are lossy, so the photo is compressed a second time. Quality loss is small at normal settings and rarely visible, but avoid converting the same picture back and forth, and keep your original JPGs. If you still have the camera original, convert from that instead. Metadata is removed, including EXIF camera details and GPS location, and orientation is applied. Some older programs, email tools and upload forms still do not accept WebP.
JPG is lossy, using discrete cosine transform compression; WebP is either lossy or lossless, depending on how the file was saved. JPG has no transparency, so the WebP result is fully opaque and looks the same on any background. For scale, a 12-megapixel photo is typically 2 to 5 MB as JPG and 1.5 to 3.5 MB as WebP. Compatibility: Every current browser displays it. Some older desktop software, email clients and upload forms still reject it.
