What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that translates binary data (like images or files) into an ASCII string format. It is commonly used when you need to safely store or transfer complex data over systems that are originally designed to handle standard text.
Image to Base64 Converter
One of the most powerful features of our tool is the ability to instantly convert images into Base64 strings. By clicking File to Base64 and selecting a PNG, JPG, or SVG, WhiteArray will instantly generate a data:image/...;base64 Data URI. You can paste this string directly into your CSS files or HTML <img src="..."> tags to embed images inline, significantly reducing HTTP requests and improving page load speeds.
Base64 to Image Decoder
If you have a massive Base64 string and want to see what it represents, simply paste it into the decoder. Our engine automatically strips out Data URI prefixes and intelligently detects raw binary payloads. Instead of throwing an error or showing unreadable binary text, WhiteArray instantly generates a visual Image Preview and provides a one-click button to download the decoded image directly to your computer.
100% Secure & Client-Side
Whether you are encoding sensitive API keys, decoding hidden text, or manipulating private images, WhiteArray handles everything locally in your browser. Your data is processed instantly and never leaves your machine—no data is ever sent to or stored on our servers.
