Choose the intended URI scope
- Use component mode for an individual value.
- Use full URI mode only when URL syntax should remain meaningful.
- Encode or decode explicitly; the tool never visits the result.
URL Encoder and Decoder
Percent-encode or decode complete URIs and individual URI components without opening any URL.
Input and results stay in browser memory in this tab. Nothing is uploaded, logged, saved, or added to the URL. No URL is fetched.
Enter text and choose an action.
URI component mode encodes individual query values or path fragments. Full URI mode preserves separators such as colon, slash, question mark, and ampersand because they define URL structure.
How OpenFileTools processes it
Local processing, explicit choices.
Standards-compatible browser URI primitives transform the bounded string locally. No DNS or HTTP request occurs.
Questions, answered.
Which mode should I use for a query value?
URI component mode is normally appropriate because it also encodes reserved separators inside the value.
Does this tool open the URL?
No. Input and output remain inert text.
