Good to Know

  • Links that are flagged as malware, phishing or spam can't be shortened, and links pointing to them are removed.
  • If you create many links in a short time, you'll be asked to wait a minute.
  • Links created here can't be edited and have no stats. To pick your own slug, edit the destination or see who clicks, create a free account and use Short Links.
