About utilities tools
These are the small jobs that come up when building websites and apps. Image to Base64 and Image to Data URI turn an image into text for embedding in HTML, CSS, JSON or templates, and Base64 to Image reverses the process with a preview and download. All three, along with the Image Aspect Ratio Calculator, run in your browser without uploading anything.
The icon generators turn one square logo into the sets each platform expects. The Favicon Generator makes favicon.ico, PNG favicons, an Apple touch icon and the HTML link tags. The App Icon Generator covers the main iOS and Android sizes, with opaque, square iOS icons as the App Store requires. The PWA Icon Generator adds a maskable icon with safe-zone padding and the icons array for a web app manifest. Padding, corner radius and background apply across every size.
The Image Placeholder Generator creates dummy images at any size up to 4000 × 4000 pixels, with your own label and colors, as a PNG download or a URL you can drop straight into a layout.
