Base64 to Image Converter

What is a Base64 String and How Does It Become an Image?

Base64 is a method of encoding binary data (like image files) as plain text. When an image is encoded to Base64, the result is a long string of letters, numbers, and symbols. This string starts with a prefix like data:image/png;base64, followed by the encoded data. This tool does the reverse - you paste in a Base64 string and it decodes it back into a viewable, downloadable image file. This is especially useful for developers who receive image data from APIs or need to extract embedded images from HTML or CSS source code.

When Do You Need to Decode Base64 to an Image?

• API Responses: Many APIs return image data as Base64 strings (e.g., AI image generation APIs, document scanning APIs). This tool lets you quickly preview and download those images.
• HTML Source Extraction: If you find a Base64 data URI inside an HTML or CSS file and want to save it as an image file, simply paste the string here.
• Email Attachments: Some email systems encode image attachments as Base64. Decode the string to recover the original image.
• Debugging: Developers use this tool to verify that Base64-encoded images are valid and display correctly before embedding them in code.

Frequently Asked Questions

Q: What image formats can be decoded?
A: Any image format encoded as Base64 can be decoded - PNG, JPG, WEBP, SVG, GIF, and more. The output will be downloaded as a PNG file.
