What is an image to Base64 converter?
An image to Base64 converter reads an image file and outputs either raw Base64 or a complete data URL. Data URLs can be used in HTML, CSS, prototypes, tests, and some API payloads.
How to use it
- Upload a PNG, JPG, WebP, GIF, SVG, ICO, or supported image file.
- Choose data URL for browser embeds or raw Base64 for API fields.
- Copy the encoded output.
Example
Input: logo.png
Output: data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA...
Common mistakes
- Base64 images are larger than the original file.
- Large production images should usually be hosted as files instead of embedded as data URLs.
- Raw Base64 needs a separate MIME type when used in HTML or CSS.
