Flow
- Select encode or decode operation.
- Pick the corresponding URI mode.
- Run once or use live mode for instant updates while typing.
Example
Worked example: round-trip conversion
- 1 Set operation to Decode and input a percent-encoded URL.
- 2 Review decoded output and edit the query text.
- 3 Switch operation to Encode and swap to rebuild encoded output.
The same interface supports both conversion directions.
How
- Paste input text into the editor.
- Set operation and codec mode from the options panel.
- Use swap to exchange input and output for reverse conversion.
Cases
- Round-trip test encoded tracking parameters quickly.
- Convert logs from encoded text back to readable values and re-encode after edits.
- Teach URI versus URI component behavior in classroom demos.
Avoid
- Using encode mode with a decode-only option configuration.
- Forgetting to update mode when switching between full URLs and query values.
- Assuming recursive decode should always stay on for every payload.
