About This Tool
Working with Base64-encoded image strings is common in web development, API responses, and data processing, but there are times when you need to convert those strings back into viewable, downloadable image files. Our free Base64 to image converter does exactly that — paste any Base64 string or data URI and instantly get a downloadable image file. This is invaluable for debugging, data recovery, and processing API responses that return image data as encoded text.
The tool is commonly used by developers who receive Base64 image data from APIs, database queries, or web scraping operations and need to convert it into a usable file format. Data analysts working with datasets that contain embedded image data also rely on this conversion. Even non-technical users may encounter Base64 strings in email attachments, configuration files, or exported data and need a simple way to view the actual image content.
The converter automatically detects the image format from the data URI prefix or the encoded binary header, so you do not need to specify whether the data represents a JPEG, PNG, WebP, or GIF. If the input is a raw Base64 string without a prefix, the tool analyzes the binary signature to identify the format. The decoded image is displayed in a preview panel and can be downloaded with a single click in the detected format.
How to Use This Tool
Paste the Base64 String
Paste your Base64-encoded image string into the input text area. You can paste a raw Base64 string or a complete data URI that includes the MIME type prefix.
Preview the Decoded Image
The tool automatically decodes the string and displays the resulting image in a preview panel. Verify that the image looks correct before downloading.
Download the Image File
Click the download button to save the decoded image as a file. The tool automatically assigns the correct file extension based on the detected format.
Choose Output Format (Optional)
If you want to convert the decoded image to a different format, you can select an alternative output format before downloading.
Advantages & Use Cases
Automatic Format Detection
No need to manually specify the image format — the tool identifies JPEG, PNG, WebP, GIF, and other formats from the encoded data.
API Response Processing
Quickly decode Base64 image data received from APIs, databases, or web services into viewable and downloadable files.
Instant Preview
See the decoded image immediately in the preview panel before downloading, ensuring the conversion was successful.
Supports Both Formats
Accepts both raw Base64 strings and complete data URIs, so you can paste output from any source without modification.
Privacy and Security
All decoding happens in your browser with no data sent to external servers, making it safe for confidential image data.
Supported Formats & Recommendations
The Base64 to image converter automatically detects and decodes JPEG, PNG, WebP, GIF, BMP, and SVG formats. Input can be provided as a raw Base64 string or as a complete data URI with MIME type prefix. The output file uses the correct extension (.jpg, .png, .webp, .gif, .bmp, or .svg) based on the detected format. If you want to save the decoded image in a different format than the source, you can select an alternative output format from the download options. All common web image formats are supported for both input detection and output conversion.
