URL Encode / Decode

This tool will help you to encode and decode URLs.


About this tool

This tool uses JavaScript's encodeURIComponent and decodeURIComponent to encode and decode a given string as described in RFC 3986. This is for protecting literal characters from being interpreted as special URL delimiters and for protecting URLs from being mangled by transmission media with character conversions (like some email systems).

Behind the scene

A URL can only consist of standard ASCII characters; other special characters must be encoded. They will be replaced by a sequence of different characters representing its UTF-8 encoding.

encodeURI is used to encode a full URL, and encodeURIComponent is used for encoding a URI component such as a query string. This tool uses encodeURIComponent only. Eleven characters are not encoded by encodeURI but encoded by encodeURIComponent.

Frequently Asked Questions

Cybersecurity or IT security protects networks, computer systems, and devices from theft or damage to their hardware and software or the data they process and from disruption or misuse of the services and functions they provide. The information is both private and business, which in turn may be personal. Overall, cybersecurity is often (but not only) directed against cybercrime. Among the most significant challenges is the lack of global, centralized cybersecurity institutions and global agreements and regulations to detect and combat cybercrime and bring about cyber resilience.
A cyberattack can lead to identity theft and blackmail attempts on an individual level. Personal data, such as credit card details or family photos, can also be stolen. Critical infrastructures, such as power plants, hospitals, and financial service providers, are essential to the functioning of our society. In addition, industrial espionage is one of the most significant risks for companies.
These presentations aim at Analysts, Security Managers, Web Developers, Software Engineers, Administrators, DevOps, DevSecOps, Team Leads, Manager, CISO, CTO, and other Executives. The slide decks serve as an introduction and provides knowledge on all aspects of the subject area. To put it straight: Benefit from these online presentations and get more insights into the cybersecurity space.
These presentations introduce the topics and convey the contents, in short, concise slides. It is crucial that the contents are as self-explanatory as possible and that the topic areas with the essential information are outlined.
Cybersecurity is a vast field, and it is probably impossible to know everything or every detail. For this reason, many more courses will follow in the coming months to ensure the broadest possible coverage.
As you might imagine, cybersecurity is a broad field. Therefore, it is probably impossible to cover everything. It would go beyond the scope to write everything down. Hence, these slide decks are not intended to be exhaustive but will provide a good starting point.
