Frequently asked questions.
WebP is a modern image format developed by Google that provides superior compression. WebP images are typically 25–35% smaller than JPEG at equivalent visual quality, and 26% smaller than PNG. This makes WebP ideal for websites where faster load times improve user experience and SEO.
Upload your JPG, PNG, or GIF image using the file picker or drag-and-drop. Choose your output quality (80% is recommended for most uses). Click Convert and download your WebP file. The conversion runs instantly in your browser.
Upload your WebP file, select your output format (JPG or PNG), and click Convert. JPG is best for photos; use PNG if the WebP image has transparency you want to preserve. Download the converted image immediately.
