IDM is a Chrome extension developed by Agenty that offers a convenient way to shorten URLs and generate QR codes. With IDM, users can create short links with custom domains, allowing for enhanced user experience and efficient tracking of link performance. The program offers a range of features, including the ability to set link expiration dates, add UTM parameters, and view click reports and link history directly within the extension. IDM also automatically copies the shortened URL to the clipboard, making it easy to share. Additionally, users can generate QR codes for each link, facilitating mobile scanning and redirection. IDM is a free tool and does not require sign-up, although public links expire after 24 hours. It serves as a good alternative to other link shortener services like Bitly, Rebrandly, and TinyUrl.
