URL Encoding Made Clear

URLs have a strict alphabet: letters, digits, and a small set of symbols. Everything else — spaces, #, &, %, and any non-ASCII character — must be escaped as %XX sequences before a browser or API will accept it.

Common use cases

  • Building query strings: Search terms and parameters with spaces or special characters.
  • API calls: Values passed to REST endpoints must be percent-encoded.
  • Scraping and automation: Read or debug encoded URLs found in logs and analytics.
  • Redirect links: Cleanly encode destination URLs used in tracking links.

Local and private

URL encoders on other sites process your links on their servers — visible to them, and to their analytics. Toolza converts entirely in your browser, so your links and search terms never leave your machine.

Frequently Asked Questions

Yes. Toolza’s URL encoder is free forever with no limits.

No. Encoding and decoding happen locally in your browser using native encodeURIComponent APIs.

URL encoding (percent-encoding) replaces unsafe characters like spaces, #, and & with a % followed by their hex code, so they can safely travel inside URLs and query strings.

Full encoding escapes everything, including reserved characters. "Preserve reserved" mode keeps : / ? & # = as-is — useful for encoding only the parts that need it.

Yes. Emoji and non-Latin characters are encoded correctly into their UTF-8 percent sequences.

Decoding a malformed string can produce garbage. If a link 404s after decode, the original had extra encoding layers — try encoding it once more.
