How to use URL
Use this for one URL component at a time: query values, path fragments, redirect values, and percent-encoded text.
- Paste or type your input.
- Load the sample if you want a quick check.
- Run the action, review the result, then copy only what you need.
Examples
Decode reserved characters
Input: a%2Fb%3Fc%3D1

Common use cases
Fix query values
Encode the value you are changing, then inspect the full query with URL Query Parser.
Compare encoding formats
Move between URL encoding, Base64 text, and HTML entities from the Encoding category.
Limitations
Component scope
This uses encodeURIComponent/decodeURIComponent. Do not encode an entire URL unless you really want every reserved separator escaped.
FAQ
Does plus mean space?
In form-style query strings plus often represents a space. This component tool preserves plus signs; use URL Query Parser for query rows.
Does this fetch the URL?
No. It only transforms the pasted text locally.
