About this tool

The Image Converter changes your images from one format to another, between JPG, PNG and WebP. Pick the format you want and, for JPEG and WebP, set the quality. Everything happens locally in your browser using the HTML canvas, your photos are never uploaded to a server, so they stay completely private. It is perfect for switching to modern WebP, getting a transparent PNG, or producing a universally supported JPG.
