URL Encoder Decoder
Encode or decode URL components, query parameter values, redirect targets, and percent-encoded text locally in your browser.
Paste text or load the example to see the result.

Common URL encoding workflows
URL encoding and decoding is most useful when you are checking query parameters, redirect URLs, tracking links, encoded API payloads, or copied browser URLs. It changes representation only; it does not validate that a destination is safe or make private values secure.
Decode one parameter value
Paste the encoded value after a query key, such as redirect=https%3A%2F%2Fexample.com%2Fthank-you, so you can inspect the real destination before using it.
Parse full query strings
Use Query String Parser when you have a full ?utm_source=... string and need each key/value separated before deciding what to decode.
Inspect full URLs first
Use URL Parser to split protocol, host, path, query, and hash, then decode only the component that needs attention.
Build clean tracking links
Use UTM Builder when campaign parameters need consistent names and encoding rather than manual copy/paste changes.
Decode query parameters
Decode a URL fragment here, then validate any JSON payload with JSON Validator or format it with JSON Formatter.
Extract links first
If URLs are buried in a report, draft, or log, start with Extract URLs and decode only the links that matter.
Use the preset workflow
For URL-encoded JSON, the Developer Data Toolkit combines decode, validate, and format steps.
Limitations and safety notes
- Encoding a full URL can encode separators like
?,&, and=. Usually you should encode only the parameter value. - Malformed percent escapes show an error instead of silently changing the input.
- URL encoding is not encryption and does not hide secrets, tokens, or private links.
Quick answer
URL Encoder Decoder is a browser-based url encoder decoder for checking copied developer data such as payloads, URLs, encoded values, identifiers, snippets, or logs without sending the input to a server.

What this tool does
Use this page when a link, query string, tracking URL, API payload, or redirect parameter contains spaces, reserved characters, encoded JSON, or percent-escaped values that need a safe decode/check/re-encode workflow.
Common use cases
Encode, decode, and inspect URL components while debugging query strings, redirects, API payloads, tracking links, or copied browser URLs.
Use URL Encoder Decoder when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Choose encode when text needs to become URL-safe, or decode when a value contains percent escapes such as %20 or %7B.
- Paste only the URL component, query parameter value, redirect target, or fragment you need to inspect.
- Copy the result, then parse query strings, validate JSON, or rebuild tracking URLs with the related tools when needed.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
Client-side only: URL encoding and decoding run in your browser. ClearUtils does not upload, store, fetch, crawl, or log pasted URL strings. URL encoding is not encryption, so do not paste private tokens or credentials.
Practical notes for this tool
Best use case
Use URL Encoder Decoder when a query value, redirect URL, callback parameter, UTM value, or API sample needs safe percent-encoding before testing or readable decoding before review.
Encode a redirect parameter

https%3A%2F%2Fexample.com%2Fcheckout%3Fplan%3Dpro%20annual
Privacy and local processing
Encoding and decoding are handled in your browser. ClearUtils does not request the URL, follow redirects, upload query strings, or store pasted values.
Limitations to know
- Encoding does not make a secret safe to share.
- Malformed percent-encoding may need manual cleanup before decoding.
- It does not validate whether a URL is reachable or allowed by a destination service.
Practical FAQ
When should I encode a full URL instead of only a parameter value?
Encode the full URL when it must be nested inside another query parameter. Encode only individual values when you are building a normal query string with separate keys and values.

4 focused answers for this page
Should I encode a full URL or only one parameter value?
Most debugging tasks need component-level encoding for one value, such as a query parameter, redirect target, or JSON fragment. Encoding a whole URL can also encode separators like ? and &, which may not be what you want.
What happens if decoded input has malformed percent escapes?
The tool shows the browser parsing error instead of changing the text silently, so you can fix broken sequences like incomplete % escapes before using the value.
Is my URL shared with the server?
No. URL encoding and decoding run locally in your browser; ClearUtils does not upload, store, fetch, crawl, or log pasted URL strings.
Is URL encoding encryption?
No. Percent encoding only makes text safe for URLs. It does not protect secrets, tokens, private links, or credentials.
