Frequently Asked Questions
Clear, accurate answers based on actual URLSRT functionality
Is URLSRT free to use for shortening links?
Yes! URLSRT is completely free for individuals and businesses. Create unlimited short links, QR codes, and landing pages without subscription fees.
Can I choose my own custom short code?
Yes. You can specify a custom alphanumeric slug (e.g., /my-product) when creating a link, as long as the slug has not already been claimed.
How does password protection work on short links?
When you assign a password to a short link, any visitor who navigates to the URL is presented with a secure prompt. The destination is only accessed after entering the correct password.
Do shortened links ever expire automatically?
By default, links never expire. However, you can optionally configure an expiration date or a maximum visit limit if you want the link to deactivate automatically.
