What Is a Base64 to Image Converter?

This tool turns Base64-encoded image data back into a viewable image. Paste a Base64 string (with or without the data:image prefix), and the image appears instantly with its format and size, ready to download. Everything runs locally in your browser — nothing is uploaded.

How to Convert Base64 to an Image

Copy the Base64 string of your image and paste it into the input box. The tool detects the format automatically (PNG, JPEG, GIF, WebP, or SVG) and shows a live preview. Click Download Image to save the file to your device.

  • Works with or without the data:image/png;base64, prefix.
  • Format and file size are detected automatically.
  • Download keeps the original image format.

Common Use Cases

  • Recovering images from Base64 strings stored in databases or JSON APIs.
  • Extracting images embedded in HTML, CSS, or email source code.
  • Verifying Base64 image data before using it in your projects.
  • Converting data URLs to standalone image files.

Tips

Base64 increases the data size by about 33%, so large images produce long strings. If you have a very long string, make sure the entire content is pasted. This tool never sends your data anywhere — everything is processed in your browser.

Frequently Asked Questions

What image formats are supported?+
PNG, JPEG, GIF, WebP, and SVG. The tool detects the format automatically from the Base64 header, so you do not need to specify it.
Do I need to include the data:image prefix?+
No. The tool accepts both raw Base64 strings and full data URLs that start with data:image/.... If the prefix is present, it is used to identify the format.
Is my data uploaded anywhere?+
No. All decoding happens locally in your browser. Your Base64 data never leaves your device.
Why does the tool say my string is not an image?+
The string may not be valid Base64, or it may encode something other than an image, such as text or a document. Double-check that you copied the full string.
How do I download the converted image?+
Once the preview appears, click the Download Image button. The file is saved in its original format, for example .png or .jpg.
