Timestamp Conversion
A 10-digit Unix timestamp is usually seconds. A 13-digit timestamp is usually milliseconds. If a date is off by a factor of 1000, check the unit first.
Unix timestamps represent one instant in time. UTC output stays stable, while local time changes based on the viewer's timezone and daylight saving rules.
QR Code Generation
The QR code tool works best with short text, links, email content, and compact payloads. Very long text may create dense codes that are harder for cameras to scan.
IP Conversion
The IP converter supports IPv4 dotted addresses, unsigned decimal integers, hexadecimal values, and IPv4-mapped IPv6 input. Values outside the IPv4 32-bit range are rejected instead of producing misleading output.
HTTP Ping Checks
The HTTP Ping tool checks web reachability over HTTP or HTTPS. It is not ICMP ping, and results can differ from command-line tools because browser networking, CORS, caching, and remote server behavior may affect the response.
