How to Use
This tool converts Base64 encoded image data back into viewable images. Base64 encoding is commonly used to embed images in web pages, emails, and data storage systems.
Step-by-Step Instructions:
- Get Base64 Data: Copy the Base64 encoded image data (must start with 'data:image/')
- Paste Data: Paste the Base64 string into the input area
- Convert: Click "Convert Base64 → Image" to render the image
- View Result: The converted image will appear in the result area
- Clear: Use "Clear" button to reset and try another image
Base64 Image Format:
- Data URI Format: data:image/[format];base64,[encoded_data]
- Supported Formats: PNG, JPEG, GIF, WebP, BMP, SVG
- MIME Types: image/png, image/jpeg, image/gif, image/webp, image/bmp, image/svg+xml
- Encoding: Uses Base64 encoding for safe text transmission
Examples:
- PNG Image: data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mNkYPhfDwAChwGA60e6kgAAAABJRU5ErkJggg==
- JPEG Image: data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAYABgAAD/2wBDAAYEBQYFBAYGBQYHBwYIChAKCgkJChQODwwQFxQYGBcUFhYaHSUfGhsjHBYWICwgIyYnKSopGR8tMC0oMCUoKSj/2wBDAQcHBwoIChMKChMoGhYaKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCj/wAARCAABAAEDASIAAhEBAxEB/8QAFQABAQAAAAAAAAAAAAAAAAAAAAv/xAAUEAEAAAAAAAAAAAAAAAAAAAAA/8QAFQEBAQAAAAAAAAAAAAAAAAAAAAX/xAAUEQEAAAAAAAAAAAAAAAAAAAAA/9oADAMBAAIRAxEAPwCdABmX/9k=

Common Use Cases:
- Converting embedded images from web pages
- Decoding images from API responses
- Extracting images from email attachments
- Converting database-stored image data
- Debugging image encoding issues
- Testing image display functionality
Tips for Better Results:
- Ensure the Base64 string starts with 'data:image/'
- Check that the MIME type matches the actual image format
- Verify the Base64 encoding is complete and valid
- Large images may take longer to process
- Some browsers have size limits for data URIs
Error Messages:
- "Please enter Base64": Input field is empty
- "Please enter a valid image Base64 starting with data:image/": Invalid format or missing data URI prefix
- "Invalid image Base64": Corrupted or invalid Base64 data
Important Notes:
- This tool only processes valid Base64 image data
- All processing happens locally in your browser
- No data is sent to external servers
- Large Base64 strings may cause performance issues
- Some very large images may not display due to browser limits
