A QR code generator
that just works.
qr.seun.app is a free QR code generator that runs entirely in your browser. No account required. No watermark on exports. Nothing you enter or generate is ever sent to a server.
What it generates
Six QR types, each one triggering a direct action when scanned:
- URL — Opens any website or link. Supports an optional logo overlay centered in the code.
- vCard+ — Adds a contact directly to the scanner's phone. Includes name, phone number, email, organisation, and LinkedIn.
- WiFi — Connects a phone to a WiFi network without typing a password. Supports WPA2, WPA3, WEP, and open networks.
- Phone — Opens the phone dialer with a number pre-filled, ready to call.
- Calendar — Adds an event to any calendar app on scan. Title, date, time, location, and description.
- SMS — Opens a pre-filled text message on the scanner's phone.
Why it was built
Most free QR code generators fail in at least one of these ways: codes that don't scan reliably across all devices, required accounts to download, watermarked outputs, or usage data sent to servers without disclosure.
The reliability failure is the most damaging — particularly with vCard codes, which routinely scan correctly on one phone and fail on another. For anything going to print, that's unacceptable. This tool was built specifically to fix that. Every QR code generated follows the established standards strictly and is tested to work across iOS, Android, and all major QR scanners.
What makes it different
- No account required — generate and download without signing up for anything
- No watermark on any export, at any quality level
- Nothing leaves your device — all generation happens locally in the browser
- Works fully offline after the first load
- Export in PNG, SVG, or PDF at HD, 2K, or 4K resolution
- Recent QR history saved locally — no server involved
Who it's for
- Individuals who need a QR code quickly, without signing up for anything
- Businesses creating QR codes for print, menus, events, or branded materials
- Designers who need clean, high-resolution vector or raster exports
- Developers who want a reliable QR utility that doesn't send data anywhere
Part of seun.app
qr.seun.app is the first tool on the seun.app platform. The plan is to build more focused utility tools on separate subdomains — each one solving a specific problem, each built with the same approach: simple, reliable, and respectful of user privacy.
