Image to Base64 Converter
Convert any image to Base64 or data URL instantly. Decode Base64 back to an image.
CSS backgrounds — embed small icons inline to eliminate HTTP requests: background-image: url("data:image/png;base64,…")
HTML <img> tags — set a data URL as the src attribute to embed an image directly in HTML.
Email templates — many email clients block external images; Base64 embedding ensures they always display.
JSON / API payloads — include images in API responses or config files without a separate file endpoint.
⚠️ Size note — Base64 increases file size by ~33%. Best for small images (icons, logos under ~10 KB); larger images should stay as regular files.
About Image to Base64 Converter
Image to Base64 Converter lets you convert any image file (PNG, JPG, WebP, GIF) into a Base64-encoded string or data URL — entirely in your browser. Use data URLs to embed images directly in CSS, HTML, or email templates without external hosting. The Decode tab reverses the process: paste any Base64 string or data URL to preview the image. Nothing is uploaded to any server.
