Image to Base64 Converter: Encode Images & Decode Base64 Online
Any image file is encoded into a Base64 data URI string by this converter so it can be embedded directly in HTML, CSS, or JSON — eliminating an extra HTTP request. PNG, JPEG, GIF, SVG, and WebP are all supported. A Base64 string can also be decoded back to a viewable image. Most useful for small icons, logos, and UI elements under 10KB. This tool is also searched for as "image base64", "base64 image encoder", "images to base64", and "image to base64 converter".
When should data URIs be used vs. image files?
Data URIs (Base64-embedded images) work best for images under 10KB — small icons, simple logos, and UI sprites. For larger images, a separate file with proper caching is more efficient because Base64 increases size by ~33% and can't be cached independently from the HTML/CSS.
Decode Base64 back to images
When a Base64 string needs to be seen as an image, it can be pasted in and the image is rendered instantly. This is handy when debugging API responses that return images as Base64, or when data URIs in CSS files are being inspected.
