Como Funciona

Upload an image or drag-and-drop it onto the page. The tool converts it to a Base64-encoded string that you can embed directly in HTML, CSS, or JSON. Copy the data URI or raw Base64 with one click.

Cuando Usarlo

  • Inline images in HTML emails — embed small images directly in the email body without external hosting.
  • CSS background images — use Base64 data URIs for small icons and patterns to reduce HTTP requests.
  • API payloads — encode images as Base64 strings for inclusion in JSON API requests.

Preguntas Frecuentes

Does Base64 increase file size?

Yes. Base64 encoding increases the data size by approximately 33%. Use it only for small images (under 10KB) where reducing HTTP requests matters more than file size.

Which image formats are supported?

Any browser-supported format works: PNG, JPEG, GIF, WebP, SVG, and ICO. The output includes the correct MIME type in the data URI.

Can I decode Base64 back to an image?

Yes. Paste a Base64 data URI into a browser address bar to view the image, or use a dedicated Base64 decoder tool.
