What is Base64 Image Decoding?

Base64 image decoding is the process of converting a Base64-encoded string back into its original binary image format. When an image is encoded into Base64, it is transformed into a long string of ASCII text, which is often used to embed images directly into HTML or CSS files (using Data URIs) or to transmit image data over APIs.

This tool reverses that process, taking the obscure text string and rendering it back into a visual image that you can view and download.

How to Convert Base64 to an Image

  1. Paste the String: Paste your Base64 encoded string into the large text area on the left. It can be a raw Base64 string or a complete Data URI (e.g., data:image/png;base64,...).
  2. Preview Instantly: Click the "Preview Image" button (or watch it auto-update if supported). The image will render in the right-hand panel.
  3. Download or View: Click the "Download Image" button to save the file to your device, or click directly on the image preview to open it in full size.

Frequently Asked Questions

1. Are my images and data uploaded to your servers?

No, your data is completely secure. 100% of the decoding process happens locally in your web browser. We do not upload your Base64 strings or images to our servers, ensuring complete privacy.

2. What image formats does this tool support?

Our tool supports all standard image formats that can be Base64 encoded, including PNG, JPG/JPEG, WEBP, GIF, BMP, and SVG.

3. Why is my Base64 string not showing an image?

Ensure you have pasted the complete string without missing characters. If it's a raw string without the data:image/...;base64, prefix, our tool will try to infer it as a PNG. If the original image was a different format, you might need to ensure the correct prefix is included.
