base64 to image
Convert Base64 encoded strings back to images.
A Base64 to image converter transforms Base64 encoded strings back into image files that you can view, download, or use in your projects. This tool is essential for developers working with Base64 encoded image data from APIs, web developers extracting embedded images, system administrators handling configuration files with Base64 images, and anyone who needs to convert Base64 strings to actual image files. By converting Base64 to images, you can extract embedded images, save images from data URLs, and work with Base64 image data from various sources. The tool processes data entirely in your browser, ensuring privacy and instant conversion without server uploads.
What is base64 to image?
Base64 to image conversion reverses the Base64 encoding process, transforming Base64 encoded strings back into binary image data. The tool accepts Base64 strings with or without data URL prefixes (data:image/format;base64,). It automatically detects the image format when possible and converts the string into a viewable and downloadable image file. This conversion is essential when working with Base64 encoded images from APIs, configuration files, HTML data URLs, or any source that provides images in Base64 format. The tool supports common image formats including PNG, JPEG, GIF, and WebP.
Common use cases
- API data extraction: Convert Base64 encoded images from API responses into downloadable image files
- Data URL extraction: Extract images embedded in HTML data URLs or CSS background images
- Configuration file processing: Convert Base64 images stored in configuration files or databases into image files
- Email attachment recovery: Convert Base64 encoded images from email systems into viewable image files
- Documentation: Extract images from Base64 encoded strings in documentation or code comments
- Data migration: Convert Base64 stored images back to file format during system migrations or data exports
Limitations and common mistakes
- Invalid or corrupted Base64 strings will result in conversion errors and cannot be processed
- The tool attempts to auto-detect image format, but some Base64 strings without proper prefixes may not be recognized correctly
- Very long Base64 strings may experience processing delays in the browser
- The tool only processes valid Base64 encoded image data. Non-image Base64 data will not produce viewable images
- Some edge cases with malformed data URLs or unusual Base64 formats may not convert correctly
How to use this base64 to image
- Paste your Base64 string into the input field (with or without the data URL prefix)
- The tool automatically detects and converts the Base64 string to an image
- View the converted image in the preview area
- Download the image file using the download button
- The tool automatically detects the image format and saves it with the correct file extension
Frequently Asked Questions
What formats are supported?
The tool supports PNG, JPEG, GIF, and WebP formats. It automatically detects the format from the Base64 string or data URL prefix when available.
Can corrupted Base64 be decoded?
No, invalid or corrupted Base64 strings cannot be decoded. The tool will display an error message if the Base64 string is malformed or does not contain valid image data.
How do I convert Base64 to an image?
Paste your Base64 string (with or without the data URL prefix) into the input field. The tool will automatically convert it to an image that you can preview and download.
What input format is required?
You can paste Base64 strings with the full data URL prefix (data:image/png;base64,...) or just the Base64 string itself. The tool handles both formats automatically.
Can I use this for any Base64 string?
The tool works with Base64 encoded image data. Non-image Base64 data (like text or other binary data) will not produce a viewable image, though the conversion may still attempt to process it.
Is my data secure?
Yes, all conversion happens in your browser. Base64 strings are never sent to any server, stored anywhere, or transmitted over the network, ensuring complete privacy.
