What is Image to Base64?

Base64 image encoding converts an image file into a text string that can be embedded directly in HTML, CSS, or JSON. This eliminates the need for separate image files and reduces HTTP requests. Base64-encoded images use the data URI scheme: data:image/png;base64,iVBORw0KGgo...

How to Use

Drag and drop an image onto the upload area, or click to browse
The image preview and Base64 string appear instantly
Use Copy Data URI to copy the full data URI (for HTML/CSS embedding)
Use Copy Raw Base64 to copy just the Base64 string (for JSON/API use)
File info shows the image type and Base64 size

Frequently Asked Questions

When should I use Base64 images?

Use Base64 for small images (icons, logos under 10KB) in HTML emails, single-file HTML documents, or when you want to eliminate HTTP requests. For larger images, use regular files — Base64 increases size by ~33% and blocks page rendering.

What file types are supported?

PNG, JPEG, GIF, WebP, SVG, BMP, and ICO. The output includes the correct MIME type in the data URI (e.g., data:image/png for PNG files).

Does this upload my image to a server?

No. The conversion happens entirely in your browser using the FileReader API. Your image never leaves your device.
