Frequently Asked Questions
Which QR format should I use for print versus web?
Use `svg` when you need clean print output that can scale without blurring. Use `png`, `jpg`, or `gif` for web previews, social posts, or quick downloads.
Can I make a QR code for WiFi or a contact card?
Yes. The tool has dedicated WiFi and vCard flows, so you can share a network login or create a scannable contact card that adds the person to a phone address book.
How much design control do I get over the QR code?
You can change size, foreground and background colors, margins, and error correction. Higher error correction is useful when the code will be printed or placed near a logo.
What should I put in the data field?
Any URL, plain text, email address, phone number, or similar string works. The main generator handles most cases, while the WiFi and contact options are better for those specific formats.
