Is there a length limit?
QR codes scale with content — short URLs fit in a small dense pattern, long text gets a busier code. Maximum theoretical capacity is ~4,000 characters; in practice keep it under a few hundred for reliable scanning.
What error correction level should I pick?
L is fastest to scan but tolerates the least damage. H tolerates ~30% damage but makes a busier code. M (medium) is the sensible default.
Will my QR code expire?
No — QR codes are just encoded text. They never expire, as long as whatever they point to (the URL) still works.
Can I add a logo to the center?
Yes, because higher error-correction levels tolerate the obscured center. Use error level H and overlay your logo on max ~20% of the area.
Is there a tracking version?
Generated QR codes have no tracking. If you want analytics, encode a short-link URL (Bitly, your own redirect service) and track clicks there.
