URL Encoder

Encode text for safer placement in URLs and query strings when reserved characters need escaping.

Run Tool

Provide exact input, inspect deterministic output, and validate with a real endpoint or runtime.

Output

Enter values to see the result.

Behavior

This page transforms plain text into a URL-encoded form that is easier to embed inside links and query parameters. It is for debugging and manual browser-side construction of URLs.

Encoding a query parameter value before testing a link manually.
Checking which characters need escaping in a copied string.

Input / Output

“hello world” becomes “hello%20world”.
Symbols in a query value are easier to inspect after explicit encoding.

Edge Cases

Validate syntax first, then evaluate semantic correctness in the target system.
Encoding an already-encoded value a second time.
Assuming a full URL and a query value should always be encoded the same way.

URL Decoder

Decode percent-encoded strings back into readable text when browser debugging or query inspection needs a quick check.

Base64 Encoder

Encode plain text into Base64 when you need a browser-side transformation for transport, debugging, or quick testing.

HTML Entity Encoder

Escape HTML-sensitive characters into entity form when you need safer display in markup-heavy contexts.

System note: verify transformed payloads with a real endpoint before production use.

Important Use Notice

Browser-side developer helper only. Verify output against a real environment, and do not paste secrets, regulated personal data, private keys, tokens, or confidential client material unless you have permission and an approved workflow.
