Convert any image to Base64 format online in seconds. Secure, fast, and free – perfect for embedding images directly into HTML, CSS, or JSON files.
Base64 is a method for encoding binary data into a text format using ASCII characters. It’s commonly used to embed images directly within HTML and CSS files, making your projects faster by reducing server requests.
When you convert an image to Base64, you get a long string that can be placed directly into code. This is especially helpful in environments where minimizing external file dependencies is crucial.
No data is sent to any server – all processing is done locally in your browser to ensure 100% privacy and speed.
Base64 encoding is supported by all modern browsers and development environments, making it a reliable option for cross-platform deployment.
The tool automatically detects the MIME type and generates a correct Data URI like: data:image/png;base64,...
Can I decode Base64 back to an image? Yes, Base64 strings can be easily converted back to image files using a decoder.
Is Base64 secure? Base64 is not encrypted – it’s just a text representation. It's meant for transport and embedding, not security.
Does this tool support large images? Yes, but Base64-encoded strings can be very large. It’s best used for icons or small graphics.
Do I need to install anything? No – this is a browser-based tool and requires no downloads or registration.
