FAQ
Q. Does this work offline?
First load fetches Google Fonts and the QR engine from a CDN. After that, input / QR generation / download all happen inside your browser. Nothing is sent to a server — even sensitive content stays private.
Q. Is there a character limit?
Effectively over 7,000 characters fit. Denser data means a finer grid that's harder to scan from a distance — shorten the URL or drop the error correction level (L) for big payloads.
Q. PNG vs SVG?
SVG is vector — great for print, scaling, posters. PNG is raster but displays everywhere instantly — web, email, social. Both free and unlimited from this tool.
Q. Does it support Korean / Japanese / emoji?
Yes — UTF-8 including emoji is fully supported. Non-ASCII chars take more bytes, so the QR grid grows fast.
Q. Does scanning a WiFi QR connect automatically?
Enter SSID, password and encryption in the WiFitab and it's encoded as the standard WIFI: format. Both the iPhone camera and the default Android camera (or Google Lens) show a “Join network” prompt on scan — one tap connects. Great for cafes, shops and offices.
Q. How does a vCard QR save a contact?
Fill name, phone, email, company, title and website in the vCardtab to generate a vCard 3.0 QR. After scanning, tapping “Add to Contacts” saves a new contact with every field filled into the phone's default contacts app.
Q. Can I put a logo in the center?
Yes. Upload a PNG·JPG·SVG under Logo (optional); it sits in the center and error correction auto-locks to H (30% recovery) so it still scans. Keep the logo under ~20% and test-scan before printing. The SVG download embeds the logo too, staying a single self-contained file.
Q. Can I use it commercially?
Yes — the generated QR codes are free for any commercial use: menus, posters, tickets, business cards, SNS profiles, anything. Note that the copyright of any logo image you embed is separate, so use images you own or have rights to.
