Convert timestamps, number bases, byte sizes, and CRON expressions.
Data conversion comes up constantly in development — Unix timestamps to human-readable dates, decimal to hexadecimal, bytes to megabytes, CRON expressions to plain English, and temperature units for IoT work. These converters handle the quick transformations you need during debugging, data processing, and documentation. Each tool provides bidirectional conversion where applicable, so you can convert in either direction from a single interface. Particularly useful for DevOps engineers working with CRON schedules, backend developers dealing with timestamps and byte sizes, and anyone who needs quick number base conversions.
