Is.Gd is a straightforward URL shortener. This free service generates a short URL that redirects to another URL you specify.
For example, I generated this short URL: “https://is.gd/UEGPhG” that now redirects to the page you are currently reading (“https://greycoder.com/is-gd-a-good-url-shortener/”).
How long do “is.gd” links I create last? The developer says:
We don’t remove shortened URLs as long as they’re created in accordance with our terms & conditions. As such, we expect them to last forever, excepting technical issues and other difficulties covered in our terms.
Basically, they request that the URLs not be used for commercial or spam-like purposes.
