About Base64 to Image Conversion

Base64 encoding is a method to represent binary data (like images) as ASCII text. It's commonly used in web development to embed images directly in HTML, CSS, or JavaScript files. Our tool helps you convert these encoded strings back to viewable and downloadable images.

Data URL Format

A complete Data URL looks like this:

data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA...

It consists of a prefix that specifies the MIME type and the Base64 data after the comma.

Common Use Cases
  • Extract images embedded in CSS or HTML files
  • Convert Base64 strings from APIs back to images
  • Decode Base64 images from email templates
  • Recover images from data stored in databases

Frequently Asked Questions

A Base64 string with a prefix will start with data:image/ followed by the format (like png, jpeg, gif) and then ;base64, before the actual encoded data. If your string starts with these characters, it includes a prefix. If it starts with letters and numbers like iVBORw0KGgoAAAANSUhEUgAA..., it doesn't have a prefix.

There could be several reasons:
  • The Base64 string might be incomplete or corrupted.
  • If you're not using a data URL prefix, you might have selected the wrong image format.
  • There might be extra spaces or line breaks in your Base64 string that need to be removed.
  • The string might not actually be Base64 encoded image data.
Try cleaning your input string by removing any spaces or line breaks, and ensure you've selected the correct format.
