Convert any image to a Base64-encoded string. Useful for embedding images directly in HTML, CSS, or JSON. Toggle between data URI and raw Base64 output.
Image to Base64 is a conversion tool that transforms image files into Base64-encoded text strings using the FileReader API. Base64 encoding represents binary image data as ASCII characters, allowing images to be embedded directly in HTML, CSS, and JSON without separate file references. This eliminates extra HTTP requests and simplifies asset management for small images like icons and logos. Our browser-based converter supports all common image formats and generates both raw Base64 strings and complete data URIs. All conversion happens locally in your browser, ensuring your images remain private.
Base64 is a way to represent binary data (like images) as ASCII text. This allows you to embed images directly in HTML, CSS, or JSON without separate image files.
A data URI includes the MIME type prefix (e.g., 'data:image/png;base64,') before the Base64 string, making it directly usable in HTML img tags or CSS background-image.
Base64 is great for small images (icons, logos) that you want to inline. For large images, regular file references are more efficient.
Yes, Base64 encoding increases the data size by approximately 33%. It's best used for small images where reducing HTTP requests is more important.
