About Image Tools

Our image tools help you create and convert graphics right in your browser, from app icons and favicons to placeholder images and QR codes. Upload a picture or start from scratch and get exactly the sizes and formats you need.

They are built for developers and designers: generate a full set of app icons from one image, turn an emoji into a favicon, extract a colour palette from a photo, or embed an image as a Base64 data URL. Each tool is fast and produces clean, ready-to-use output.

Because everything runs on your device, your images are never uploaded to a server, so they stay completely private.
