What can I encode in a QR code?

URLs, plain text, email addresses (mailto:), phone numbers (tel:), Wi-Fi credentials, vCard contacts and map locations. Any text up to ~2,900 characters works.

Do these QR codes ever expire?

No. The data is encoded directly in the pattern — no redirect server is involved. The QR works forever as long as the destination URL remains active.

What resolution can I download?

Up to 1024×1024 pixels — sharp enough for posters and product packaging. For small prints like business cards, 300×300 px is sufficient. SVG download is infinitely scalable.

Do colors affect scanning reliability?

Yes. Always keep strong contrast between foreground and background. Dark foreground on a white background scans most reliably on all devices.

What error correction level should I choose?

Medium (15%) works for most digital uses. Use High (30%) for printed materials that may get worn, dirty or partially obscured. Higher correction makes the pattern denser.

Do QR Codes Expire?

QR codes generated here never expire. The data is encoded directly inside the pattern — there is no link shortener or redirect server. The QR will keep working as long as the destination URL remains active. This differs from paid QR services that expire codes after a trial period.

Tips for Better QR Codes

Keep URLs short. Shorter content = simpler pattern = faster, more reliable scanning.
Use High error correction for printed materials that may get dirty or slightly damaged.
Contrast matters: dark foreground on white background scans fastest.
Test before printing. Always scan the downloaded PNG with your phone first.
Minimum print size: at least 2 cm × 2 cm on a business card.
