What is Image to Base64 Conversion?
Base64 encoding converts binary image data into an ASCII string using a set of 64 characters. This makes it easy to embed images directly into HTML, CSS, or JSON without separate file requests.
Common use-cases include embedding small icons in stylesheets, reducing HTTP requests, storing images in databases, or sharing visuals in environments where file uploads are restricted.
Our free online tool instantly transforms JPG, PNG, GIF, and WebP images up to 10 MB into ready-to-paste Base64 data URIs—no registration required.
