Email QR Code

Generate a mailto QR code that opens your email app with recipient and optional subject/body prefilled.

Business Card QR Code

Create a business card QR code that saves a vCard in one scan. It fits business cards, visiting cards, name cards, badges, and resumes without needing sign-up or an app.

vCard QR Code

Make a vCard (contact info) QR code so people can save your details in one scan.

Phone QR Code

Scan to start calling instantly (tel: link).

URL QR Code

Convert a website link to a QR code instantly, then download a clean SVG or PNG.

Redirect QR Code

Create a redirect QR code for campaigns, menus, packaging, posters, and any QR that may need a controlled destination path.

Use cases & print ideas

Matching pages that explain where this QR type works best before you open the generator.

Business Card QR Code Ideas for Contact Sharing

Use a business card QR when the next step should be saving a contact, not typing details or visiting a plain web page.

Redirect QR Code Use Cases

Use Redirect QR for a controlled destination path; only hosted dynamic QR lets the printed asset stay fixed while the destination changes after launch.

A mailto QR code (also searched as “QR code mailto” or “QR code that opens email”) opens your email app with a new draft. Start with the Mailto / Email QR code generator.

Mailto formats (copy/paste)#

Basic: mailto:hello@example.com

Subject: mailto:hello@example.com?subject=Hello

Subject + body: mailto:hello@example.com?subject=Hello&body=Hi%20there

Step-by-step#

Enter the recipient email address.
Optional: add a subject and message.
Scan-test on iPhone and Android (some scanners ignore subject/body).
Download SVG for print or PNG for sharing.

Tips (avoid scan failures)#

Keep the subject/body short (long mailto strings make the QR denser).
Use SVG for sharp printing and keep a clear quiet zone.
Troubleshooting: QR not scanning fixes.

If you need analytics#

Mailto opens an email draft and may be hard to track. If you need measurement, use a URL QR to a contact page with UTM parameters instead. See UTM tracking for QR.

For other payload types, see URL/Phone/SMS/Email payload formats.
