Questions about this tool
How does this tool work: URL encode & decode?
Free, no sign-up, right in your browser. Paste text, choose encode or decode and apply. Copy the result or save TXT.
Why does a plus sign not become a space?
This tool uses percent encoding for URL components. + stays a plus; spaces are %20. The different plus notation used in HTML forms is not interpreted automatically.
What inputs, outputs and limits apply?
Input: Text or a percent-encoded URL component. Output: Encoded or decoded text; TXT download. Limits: At most 500,000 characters. Encodes URL components, not entire URLs. Spaces become %20; + stays a plus when decoding. Invalid percent or UTF-8 sequences are rejected.
