URL Decoder Online
Decode percent-encoded URL text.
Convert percent-encoded URL components back into readable text. Paste the input, make the change, then read the result before you copy it elsewhere.
Malformed percent sequences will return an error.
Ready — input is processed locally.
This utility runs on the current device for the supported workflow. Kaazo does not need the pasted input to calculate the result.
URL Decoder: what the result contains
Convert percent-encoded URL components back into readable text.
Encode the component, not blindly the whole URL
Query values often need escaping because spaces, ampersands, slashes and other characters can have structural meaning in a URL. Encoding an entire URL as one component can also make it unusable.
Decode only as many times as the source requires. Repeated decoding can change data that was intentionally encoded.
Don’t ask URL Decoder to do a different job
Use URL parsing tools when you need to inspect or rebuild scheme, host, path and query parts separately.
Example and result checks
The component Bengaluru%20South decodes to Bengaluru South, and %26 represents an ampersand within a value. That distinction matters when inspecting a query string: an encoded ampersand is data, whereas a literal & may separate parameters. Decode a specific value rather than blindly altering the entire address.
If a value contains %2520, one decoding pass produces %20, not a space. Repeating the operation can change intended data and sometimes break a signature or redirect parameter. When a URL is failing, examine the path and query separately and keep the original encoded value for comparison.
FAQ
What does URL Decoder actually do?
Convert percent-encoded URL components back into readable text.
What limitation matters most?
Query values often need escaping because spaces, ampersands, slashes and other characters can have structural meaning in a URL. Encoding an entire URL as one component can also make it unusable. Decode only as many times as the source requires. Repeated decoding can change data that was intentionally encoded.
Does formatted or converted output prove the data is valid for my application?
No. URL Decoder can perform the syntax or data operation described here, but your application can still impose its own schema, business rules, encoding or security requirements.
