Image to Base64

Image to Base64 converts images into Base64-encoded text — and also does the reverse, turning a Base64 string back into an image. This encoding format is widely used by developers to embed images directly into HTML, CSS, or JavaScript code, eliminating the need for a separate file request.

To encode, select an image and the tool immediately displays the corresponding Base64 string in Data URI format (e.g., `data:image/png;base64,...`). You can copy the full string with one click. To decode, paste a valid Base64 string and the corresponding image will be rendered, ready to download as a file.

Practical use cases: embedding small icons or logos directly in CSS stylesheets without extra HTTP requests, including images in HTML emails to ensure they display even without a working image server, storing images in databases as text within JSON or XML fields, and testing APIs that accept Base64-encoded images as payload.

The conversion runs entirely in the browser using the native JavaScript FileReader API. No files are sent to external servers, and no account or extensions are needed.
