Use Image to Base64 when embedding small images directly in HTML or CSS to reduce HTTP requests, creating data URIs for email templates where external images may be blocked, or storing images as text strings in databases and JSON. It is ideal for icons, logos, and small decorative images under 10KB.
The conversion is lossless — the Base64 string perfectly represents the original image data. Supported formats include PNG, JPEG, GIF, WebP, SVG, and ICO. The output includes the proper data URI prefix (data:image/png;base64,...) ready for direct use in HTML img tags and CSS background properties.
Your images are converted entirely in your browser using the FileReader API. No image data is ever uploaded to any server, making it completely safe for converting proprietary graphics, screenshots of sensitive data, and company logos. The images never leave your device.
This tool converts images to Base64 strings. To convert a Base64 string back to an image file, use our Base64 Encode/Decode tool which can decode Base64 data. The resulting Base64 string can be used directly in HTML, CSS, and JavaScript without needing a separate image file.
