Frequently Asked Questions

What is a Base64 image data URI? +

A data URI embeds the image directly in your HTML or CSS as text: data:image/png;base64,iVBORw0KGgo.... This eliminates a separate HTTP request for the image file, useful for small icons, backgrounds, and email templates.

What image formats are supported? +

PNG, JPG/JPEG, GIF, WebP, SVG, BMP, ICO, and most common image formats are supported. The MIME type is automatically detected from the file and included in the data URI.

How large will the Base64 output be? +

Base64 encoding increases file size by approximately 33%. A 100KB image becomes roughly 133KB as Base64 text. For images over 50KB, linking to the file is usually better for performance than embedding.

How do I use this in CSS? +

Copy the full data URI and use it as: background-image: url("data:image/png;base64,..."); In HTML: <img src="data:image/png;base64,...">. For email templates, inline data URIs ensure images display without external loading.

Is my image uploaded to a server? +

No. The entire conversion runs in your browser using the FileReader API. Your image never leaves your device and is never sent anywhere.
