Használat

  1. Open the tool — Open this LocalKit page and wait for the interactive controls to load.
  2. Provide input — Paste or type your content (or set options). Data stays in the browser.
  3. Run the action — Use the primary button or live controls to generate the result.
  4. Copy the result — Copy the output into your editor, terminal, or documents.

Korlátok

Requires JavaScript. Extremely large inputs may slow the browser tab. Results depend on your browser APIs; there is no server-side processing quota because nothing is uploaded.

When to use

When you want a quick, free utility without creating an account or sending content to an online converter.

When not to use

When you need server-side integration, batch automation at scale, or certified compliance tooling.

Privacy note

Tool inputs are processed in your browser only. Theme, language and favorites may use localStorage; hosting may keep standard access logs (IP, UA, URL) without tool payloads.

GYIK（5）

Parse or build?

Paste a query to inspect keys/values, or edit fields to rebuild a query string.

Duplicate keys?

Behavior follows common parsing rules—check output if APIs expect arrays.

Is data sent anywhere?

No. Parsing stays in the browser.

Include the leading ?

Optional. Tools usually accept with or without ?.

Encoding of values?

Values should be percent-encoded in URLs; decode to edit human-readable text.
