How to image to base64
Encode image files into Base64 or Data URI strings, then decode valid image strings back to files. Raw Base64, Data URI, HTML/CSS snippets, clipboard and validated reverse decoding.
Follow these steps
- Select an image to produce its encoded text.
- Switch between Base64, Data URI, CSS or HTML code.
- Copy the code or paste a valid Base64 string to decode and download an image.
Know the limitations
Base64 makes strings larger than the original binary file; it does not compress images. Avoid embedding large assets in HTML.
When Base64 is useful
Base64 encodes existing image bytes as printable text. A Data URI adds a MIME type so a browser can display the image directly inside HTML or CSS. This is most practical for tiny assets and developer examples.
Real-world examples and quality tips
Base64 is not compression or encryption. It usually increases the text length and anyone receiving the code can decode the picture. For full-size photographs, linking a separate file is typically more efficient.
