Web & URL tools
URLs carry a surprising amount of structure: schemes, hosts, ports, paths, query parameters, fragments and campaign tags. These tools break that structure apart so you can read it, and put it back together so you can share it without typos.
Query String Parser
Parse query strings into readable key/value pairs, or rebuild one from scratch.
URL Validator
Check a URL's syntax, scheme, host shape and length with a clear pass/fail checklist.
UTM Builder
Build campaign tracking URLs with UTM parameters, with optional slug formatting.
Questions about web & url tools
Are the web & url tools free to use?
Yes. All 4 tools in this category are free, need no account and have no usage limits. ToolzKit is funded by keeping the site cheap to run, not by gating features.
Does my data get uploaded anywhere?
Every tool in this category runs its processing in your browser using ordinary JavaScript. Your input is not sent to a server, and it is not written to storage when you leave the page.
Can I use these tools on a phone?
Yes. The layouts adapt to narrow screens, editors stack vertically instead of side by side, and copy buttons stay reachable without horizontal scrolling.
How do I find a tool quickly?
Press the forward slash key, or Ctrl+K on Windows and Cmd+K on macOS, to open the command palette from any page. Type a few letters and press Enter.
