JPG to WebP is a free online tool that converts JPG photos into the modern WebP format in your browser, producing images that are typically 25 to 34 percent smaller at similar quality with no upload.
Why WebP is smaller
WebP is a modern image format developed by Google that compresses photographs more efficiently than JPG. At equivalent visual quality, WebP files are typically 25 to 34 percent smaller, which means faster page loads, lower bandwidth, and quicker uploads. For a website with many images, switching to WebP can noticeably improve loading speed and Core Web Vitals scores.
Browser and platform support
WebP is supported by every major modern browser, including Chrome, Firefox, Safari, and Edge, so images display correctly almost everywhere. A small number of older programs and legacy email clients do not recognize WebP, so for maximum compatibility keep a JPG copy when you must support very old software. For the web, WebP is the better default.
Quality control
Like JPG, WebP quality is adjustable, so you can trade a little sharpness for an even smaller file. A high setting keeps photos looking clean while still beating JPG on size. WebP also supports lossless mode and transparency, making it flexible enough to replace both JPG and PNG in many situations on the web.
Private conversion
JPG to WebP runs in your browser. The photo is drawn to a canvas and encoded as WebP locally, then returned as a download. Nothing is uploaded or stored, so your images never leave your device. The conversion is near-instant for a typical photo.
