Base64 to Image Converter

This tool converts Base64 encoded strings back into downloadable image files. It's useful for extracting images from APIs, JSON data, email attachments, or any system that stores images as Base64 strings.

The tool supports all common image formats including PNG, JPEG/JPG, GIF, WebP, and BMP. The format is automatically detected from the Base64 data or can be inferred from the data URL prefix.

No, the data URL prefix (like "data:image/png;base64,") is optional. You can paste just the Base64 string without the prefix, and the tool will automatically detect the image format and add the appropriate headers.

The tool validates the Base64 string format and checks if it represents a valid image. If the string is invalid or doesn't contain image data, you'll see an error message explaining the issue.

While there's no strict limit enforced by the tool, very large Base64 strings may cause performance issues in your browser. For best results, use reasonably sized images (under 10MB when decoded).

Yes! The tool supports both methods - you can either paste the Base64 string directly into the textarea or upload a file containing the Base64 data. Simply toggle between "Paste Base64 String" and "Upload Base64 File" modes at the top of the tool.

The tool automatically generates filenames with timestamps to ensure uniqueness and avoid conflicts. Filenames follow the format "base64-image-YYYY-MM-DDTHH-mm-ss" with the appropriate file extension based on the detected image format.

The tool first checks for a data URL prefix that specifies the format. If not found, it analyzes the Base64 signature to identify common image formats like PNG, JPEG, GIF, WebP, and BMP.

Yes, once you convert the Base64 string, the tool displays a preview of the decoded image along with format information, so you can verify the result before downloading.

Yes, all conversion happens locally in your browser. Your Base64 strings and images are never uploaded to any server, ensuring complete privacy and security of your data.

If the image appears corrupted, check that your Base64 string is complete and hasn't been truncated. Also ensure there are no extra characters or line breaks in the middle of the Base64 data that might break the encoding.

Currently, the tool processes one Base64 string at a time. For multiple conversions, you'll need to convert each string individually. This ensures accuracy and allows you to verify each conversion.

Common use cases include extracting images from API responses, processing email attachments, converting embedded images from JSON/XML data, debugging web applications, and working with systems that store images as Base64 strings in databases.
