Explore a collection of focused technology utilities built to help you calculate, inspect, compare, and understand common technical problems. Each tool is designed around a specific task rather than trying to combine unrelated functions into one complicated interface.
Internet Speed & Download Time Calculator
Estimate download times from connection speed and file size, while accounting for the difference between theoretical and effective transfer rates.
Open ToolData Storage Unit Converter
Convert between decimal storage units such as GB and TB and binary units such as GiB and TiB.
Open ToolURL Component Analyzer
Break a URL into its protocol, hostname, port, path, query parameters, fragment, origin, and other components.
Open ToolHTTP Status Code Explorer
Explore common HTTP response codes and understand what different success, redirect, client-error, and server-error responses mean.
Open ToolDNS Record Explorer
Explore common DNS record types and learn how records such as A, AAAA, MX, CNAME, TXT, and CAA are used.
Open ToolDisplay Resolution & Aspect Ratio Calculator
Calculate display aspect ratio, total pixel count, and approximate megapixels from a screen resolution.
Open ToolFile Extension Explorer
Look up common file extensions and identify their typical formats, categories, and uses.
Open ToolPassword Entropy Checker
Estimate the theoretical entropy of an example password based on its length and detected character set.
Open ToolWi-Fi Standard Explorer
Compare major Wi-Fi generations, their IEEE standards, frequency bands, and important technical developments.
Open ToolUnicode Character Inspector
Inspect Unicode characters, code points, hexadecimal values, UTF-16 units, and UTF-8 byte representations.
Open ToolUsing The Tools
These utilities are intended for practical exploration and estimation. Results can depend on technical assumptions, device capabilities, network conditions, software behavior, and the way different systems implement a standard. Where those limitations matter, the individual tool explains them alongside the result.
