Free online tool to decode Base64 strings to PNG images. 100% private, runs in your browser.
PNG (Portable Network Graphics) is the most popular lossless image format on the web. It supports transparency, making it ideal for logos, icons, screenshots, and graphics where quality matters.
This tool automatically detects the format and renders it as an image in your browser. Perfect for debugging APIs, testing Data URLs, or inspecting encoded image data during development.
All conversion happens locally in your browser — your data never leaves your device.
Yes! The tool fully supports PNG with alpha channel (transparency). The decoded PNG will preserve all transparency information exactly as encoded.
PNG is lossless, meaning no quality is lost when saving. It supports transparency. JPEG is lossy and better for photographs.
No, this tool only decodes Base64 to PNG. If your Base64 data is JPEG format, use the Base64 to JPG page instead.
In JavaScript: const canvas = document.createElement("canvas"); const dataUrl = canvas.toDataURL("image/png");
PNG is perfect for logos, icons, screenshots, graphics with text, and any image that needs to stay crisp at any size.
