Component rules
Encode per component—encoding an entire URL twice is a common mistake. Spaces become `%20` or `+` in queries depending on context.

URL encoding escapes reserved characters (`&`, `=`, spaces) so servers parse parameters unambiguously. Use it when you are hand-building URLs, debugging redirects, or fixing analytics parameters. See also Base64 encoder for a related utility in this cluster.
How to use this calculator
- Open the tool: Pick encode or decode.
- Tune inputs: Paste the component—not always the full URL unless the tool expects it.
- Read the output: Copy the result into your code or ticket.
Real-world examples
- Search query `hello world`: Becomes `hello%20world` in the query portion.
- Email in param: Encode `@` to avoid truncation at delimiters.
Tips & gotchas
Let your HTTP client encode parameters automatically when possible—hand-encoding is error-prone.
FAQ
Plus vs %20?
Both appear in the wild—servers usually accept both in query strings; be consistent in tests.
Does this tool send my text to a server?
Calciverse runs in your browser; we do not store your inputs on our servers for these utilities. Anything that uses network APIs (for example DNS lookup) only sends what you explicitly request.
Why do results differ from another site?
Rounding, defaults, and implementation details (color spaces, tokenizers, DNS resolvers) can differ. Compare definitions, not just the headline number.
