URL Decoder
Decode percent-encoded URL strings back to human-readable format.
About the URL Decoder
A URL decoder reverses percent-encoding, transforming encoded sequences (such as `%20`, `%2F`, `%26`, `%3F`) back into human-readable plain text, spaces, and punctuation symbols.
When inspecting tracking links, debugging server access logs, or analyzing encoded API webhook payloads, URLs often look like unreadable strings of percent signs and hex numbers. Pasting them into this tool instantly restores the original text and characters.
The decoder automatically handles both standard percent-encoding (`%20`) and form submission plus-signs (`+`), accurately decoding international UTF-8 characters, accented letters, and emojis.
Encoded URL string: `https%3A%2F%2Fexample.com%2Fsearch%3Fq%3Dcats%20%26%20dogs` Decoded output: `https://example.com/search?q=cats & dogs`
Tips for best results
- If decoded text still contains percent sequences (such as '%2520'), the string was double-encoded; run the decoder a second time to fully unwrap it.
- Use the decoder when troubleshooting tracking links to verify that UTM parameter values were captured cleanly.
- Decoded URLs can be safely copied directly into web browser address bars.
