💡 Tips
- • Base64 encoding converts binary data into ASCII text format
- • File encoding preserves exact binary content - useful for embedding files in text
- • Data URLs with file encoding include proper MIME types for web compatibility
- • URL-safe Base64 replaces '+' with '-' and '/' with '_' for safe URL transmission
- • MIME format adds line breaks every 76 characters as per RFC 2045
- • Large files will produce very long Base64 strings - use with caution
