Encoded output uses encodeURIComponent. Decoding catches malformed sequences so you can fix them before shipping to production.
Keep URL parameters and payloads safe
Avoid broken redirects and garbled API requests. Encode text before you drop it into query strings or webhook payloads, then decode responses to double-check downstream data.
The tool mirrors JavaScript's native helpers, so what you see is what your application will produce—no surprises when you paste results into code.
Where it helps
- QA teams validating redirect URLs and query parameters.
- Developers preparing payloads for OAuth state, webhooks, or signed URLs.
- Support engineers decoding end-user links to diagnose issues.
Tips for accurate encoding
encodeURIComponent is perfect for query parameters. If you need full URL encoding (including slashes), wrap the entire URL yourself or use encodeURI instead.
Need slugs or developer-friendly casing first? Pair this with Slugify for clean inputs.
Sample conversions
- Encoding a query value
- “q=utilsverse tools & converters” → “q%3Dutilsverse%20tools%20%26%20converters”
- Decoding a webhook payload
- “status%3Dready%26source%3Dapi” → “status=ready&source=api”

FAQ highlights
Will spaces become plus signs? No. encodeURIComponent encodes spaces as %20, which is widely accepted in modern browsers and APIs.
Can I encode entire URLs? encodeURIComponent is ideal for individual components. If you need to encode an entire URL, apply it to each parameter or use encodeURI manually before pasting here for validation.
