Frequently Asked Questions

How do I shorten a URL?

Paste your URL on the homepage and click Shorten Link. The browser calls POST /api/shorten.php with JSON { "url": "https://..." }.

How do I generate a QR code?

Use the Quick QR Generator on the homepage, or request GET /api/qr.php?data=YOUR_URL&size=250 for a PNG image.

What are claimable links?

Some NFC/QR links ship without a destination. On first visit you claim the link with your name and URL. Later visits redirect automatically. Edit at /{code}/edit using the same name.
