Convert Images to Base64 Strings
Encode any image as a Base64 string with our free online tool. Base64 encoding converts binary image data into a text string that can be embedded directly in HTML, CSS, or JavaScript code. This eliminates the need for separate image file requests, which can improve page load performance for small images.
Web developers commonly use Base64 encoding for small icons, logos, and UI elements to reduce HTTP requests. Email developers use it to embed images directly in HTML emails. Our tool generates the complete data URI string ready to paste into your code.
When to Use Base64 Images
Base64 is best for small images under 10KB like icons and simple graphics. For larger images, regular file references are more efficient. Our tool shows you the encoded size so you can decide whether Base64 encoding makes sense for your use case.
