How to use url encoder & decoder
- Paste text into the editor. Inputs are limited to one million characters.
- Choose an operation where available, then run the tool.
- Review the result, copy it or save a text file.
A simple example
A component containing hello world becomes hello%20world.
What to keep in mind
Component mode escapes reserved separators; full URI mode preserves them. Decoding does not check URL safety.
Good questions. Clear answers.
Does my text leave the device?
No. This tool processes text in your browser and does not retain it.
Can I undo a change?
Your original input stays in the input editor. The result appears separately.
