Convert images to Base64 encoded strings instantly. Fast, secure, and 100% free.
Upload an image file to convert it to Base64 format
Supported formats: JPG, PNG, GIF, WebP, SVG (Max 10MB)
Image to Base64 conversion is the process of encoding image files into Base64 format, which represents binary image data as ASCII text. This allows images to be embedded directly into HTML, CSS, or JSON without requiring separate file requests.
This tool converts your image files into Base64 encoded strings that can be used as Data URIs. Data URIs are particularly useful for embedding small images directly in web pages, reducing HTTP requests and improving page load performance in certain scenarios.
Embed small images directly in HTML/CSS to reduce HTTP requests
Include images in HTML emails without external hosting
Send image data through APIs as text-based Base64 strings
Store small images as Base64 in local storage or databases
Yes, all conversion happens entirely in your browser. Your images never leave your device and are never sent to any server, ensuring complete privacy and security.
This tool supports all common image formats including JPG, PNG, GIF, WebP, SVG, BMP, and more. The maximum file size is 10MB.
Base64 is the encoded string only, while Data URI includes the full format with MIME type prefix (e.g., data:image/png;base64,...). Use Data URI for direct embedding in HTML/CSS.
Base64 encoding increases file size by ~33%. It's best for small images, icons, or when reducing HTTP requests is more important than file size. For large images, use regular image files.
