Image Converter, JPEG to PNG, PNG to WebP, and More

Image formats serve different jobs. JPEG is best for photos because of its strong lossy compression. PNG is best for graphics and screenshots because it is lossless and supports transparency. WebP is a modern format from Google that beats both on file size for most content and is now supported across every mainstream browser. This converter lets you move between the three in any direction. Drop an image in, pick the output format, optionally adjust quality for the lossy formats, and download the result. The conversion uses the browser's built-in Canvas API, so it works offline once the page is loaded and never uploads your image to any server. That makes it a fine choice for sensitive screenshots, internal product photos, and anything else you would rather not hand to a stranger's site.
