URL Encoder / Decoder — free online tool
Encode query parameters for fetch calls or decode percent-escaped strings returned by analytics tools.
When to use URL Encoder / Decoder
Build query strings and decode messy links copied from analytics or email clients.
Useful when you want a quick answer without pasting sensitive data into random chat bots.
What URL Encoder / Decoder does not do
Encodes/decodes components—it does not shorten URLs, check HTTP status, or build OAuth flows.
How to use URL Encoder / Decoder
- Paste the text or URL component into URL Encoder / Decoder.
- Choose encode or decode mode depending on whether you see %20 sequences.
- Run the action and inspect the output box.
- Copy the result into fetch URLs, query strings, or log analysis notes.
Practical tips
- Encode query values, not the whole URL—encoding the slashes breaks the path.
- Decode percent-escaped strings from logs to read what a user actually requested.
- Spaces become %20 (or +) in query strings; pick the form your backend expects.
Example
Encode “hello world” in a query value to hello%20world before a fetch URL.

Limitations
Component encoding, not full URL parsing with auth. Invalid percent sequences may throw on decode.
