Best Practices & Tips

✓Validate input before conversion. Ensure your BASE64 is valid before converting to IMAGE. Invalid BASE64 often produces unexpected IMAGE results.
✓Review conversion results. Spot-check the IMAGE output to ensure data structure and values are preserved correctly. Pay special attention to nested objects and special characters.
✓Handle conversion edge cases. Test with empty values, null fields, special characters, and large datasets. BASE64-to-IMAGE conversion can have nuances that require attention.
✓Use related tools in sequence. After conversion, use our IMAGE formatter and validator to ensure the output is clean and valid. This creates a reliable conversion workflow.

Troubleshooting Common Issues

Problem: Conversion output is missing data or incorrect

Solution: First validate your BASE64 input. Invalid BASE64 often converts to incomplete IMAGE. Also check if the data structure is compatible - some BASE64 features may not have IMAGE equivalents.

Example: BASE64 comments or special attributes might not convert to IMAGE if IMAGE doesn't support those features.

Problem: Special characters appear corrupted after conversion

Solution: Ensure your BASE64 uses proper character encoding (UTF-8). Special characters, emojis, or international text require consistent encoding throughout the conversion process.

Example: If you see � or garbled text, your source BASE64 might not be UTF-8 encoded.
