Base64 to Image
Preview an image supplied as encoded text and save a local copy. It is useful when an application returns image data in a data URL instead of a separate downloadable file.

How to use this tool
Paste the image payload without surrounding JSON quotes or explanatory text. If a data:image/png;base64, prefix is present, its media type should match the encoded image.
Results and examples
For a PNG data URL, first confirm that the preview renders, then download and reopen the file. A plausible prefix alone does not prove that the encoded image is intact.
Limitations
- Long data URLs can require considerable browser memory.
- The preview does not authenticate the origin or trustworthiness of an image.
