URL Encoder and Decoder

What URL Encoder and Decoder does

Percent-encode text for use in URL components or decode valid percent-encoded sequences into readable text.

Worked example

How it works

URL encoding converts bytes into percent-prefixed hexadecimal sequences where required. Decoding reverses valid sequences using the selected text encoding.

Developer workflows

• Prepare query parameter values
• Inspect encoded callback and redirect URLs
• Debug paths containing spaces or Unicode text

Security and compatibility checks

• Encode individual components rather than blindly encoding an entire URL.
• Decoding untrusted input does not make it safe for HTML, SQL or redirects.
• A plus sign may represent a space in form-encoded query data but not every URL component.

Frequently asked questions

Should I encode the whole URL?

Usually no. Encode each path segment or query value while preserving structural characters such as : / ? and &.

Is URL encoding encryption?

No. It is a reversible transport representation.
