Common mistakes

                        
    
                                                            
  • Encoding a full URL when only a query parameter value should be encoded.
    •

FAQ

                        

                                                            

                                    Should I encode a full URL or only a parameter?
                                    
Usually encode only the component that is placed inside another URL.

                                

                                                            

                                    Does this tool call a server?
                                    
No. It runs locally in the browser.

                                

                                                            

                                    Can it parse query parameters?
                                    
Yes. The full URL mode lists query parameters when the input is a valid URL.
