When you use someone else's service, you must follow their rules. You've painstakingly written an article and carefully designed an image. When you finally find a place to showcase your masterpiece, the service website gives you a sharing link that is extremely long. When others receive the URL you provide, the excessive length may deter them, leading them to question whether it leads to a malicious site. Additionally, long URLs are harder to remember and can disrupt the fixed structure of web pages. Some websites even have character limits for image link addresses, causing all sorts of unnecessary trouble. All these issues point to one solution: free URL shortening services.
