About This Tool

The Base64 to Image Converter takes a Base64-encoded string and renders it as a viewable image that you can preview and download. This is the reverse of encoding an image to Base64 and is essential when working with APIs, databases, or codebases that store images as text strings.

Paste any valid Base64 image string - with or without the data URI prefix - and the tool instantly decodes it into the original image. You can preview the result right in the browser and download it in the detected format. The tool automatically identifies the image MIME type from the data URI header or lets you specify it manually.

This converter runs entirely in your browser using JavaScript. No data is sent to any server, keeping your content private and the conversion instantaneous regardless of your internet connection speed.

Frequently Asked Questions

The tool accepts both raw Base64 strings and full data URIs (e.g., data:image/png;base64,...). If you paste a raw string, you can select the image format manually to generate the correct output.
Any format that was originally encoded - including PNG, JPEG, GIF, SVG, WebP, BMP, and ICO. The format is determined by the MIME type in the data URI or your manual selection.
Yes. Once the image is decoded and displayed, click the download button to save it to your device in the detected format.
The string may be corrupted, truncated, or not actually represent an image. Ensure you have the complete Base64 string. Also check that there are no extra whitespace characters or line breaks that might have been introduced during copying.
There is no hard limit in this tool, but very large strings (over 10 MB of encoded data) may cause your browser to slow down. For extremely large images, consider using a file-based workflow instead.
