Create QR codes & barcodes
Turn links, contacts, Wi-Fi and events into QR codes, and product, logistics, medical and postal numbers into barcodes. Pick dot shapes, colors, frames, error correction level and save resolution.
How to use it
Choose QR Code or Barcode on the Generate tab
Pick an information type for QR codes (Text, Website, WiFi…) or a code type for barcodes (Code 128, EAN-13…). Use “Order” to move the types you use most to the front.
Enter the content
Fields match the type you picked. The preview updates as you type, and barcodes show why an input isn’t valid right below the field.
Style it, then save or share
Adjust the look and save quality under “QR Style” or “Barcode Settings”, then tap Save (to your gallery) or Share.
QR code types
There are 10 information types. Non-Latin text such as Korean works fine (UTF-8).
| Type | Fields | What’s encoded |
|---|---|---|
| Text | Text | The text as typed |
| Website | URL | The address as typed (include https:// yourself) |
| Contact | Name, Phone, Email, Company, Title, Address | vCard 3.0 contact card (empty fields are left out) |
| WiFi | WiFi Name (SSID), Password, Security | WIFI:T:…;S:…;P:…;; — scanning it joins the network |
| Clipboard | Text (filled from your clipboard when you pick it) | The text as typed |
| Recipient, Subject, Message | mailto: link with subject and body | |
| SMS | Phone, Message | sms: link with body |
| Phone | Phone | tel: link |

- Location: tap the map, search for an address, or use your current location
Styling QR codes
Under “QR Style”, adjust Dots, Corners, Background, Text and Settings. The preview updates right away.
| Option | Choices |
|---|---|
| Dot shape | square, dots, rounded, extra-rounded, classy, classy-rounded (6) |
| Corner square shape | square, dot, extra-rounded (3) |
| Corner dot shape | square, dot (2) |
| Dot & background color | 15 common colors, or a color wheel / HEX |
| Corner colors | 10 common colors or custom, set separately from the dots |
| Frame | No Frame + 15: Envelope, Play Button, Hand Phone, Film Strip, Beer Mug, Car, Coffee Cup, Smartphone, Receipt, Calendar, Clipboard, Chat Bubble, Notebook, Shopping Bag, Gift Box (swipe the preview to choose) |
| Frame text color | Auto (black or white to suit the background), 10 colors, or custom — the frame text is fixed to “Scan me!” |
| My presets | Save the current style and frame under a name (up to 20 characters), tap to apply, long-press to delete. “Default” resets anytime |
Error correction level
QR codes carry extra data so they still scan when part of the code is dirty or covered. Higher levels survive more damage, but the same content needs more modules, so the code gets denser. Choose it under QR Style > Settings.
| Level | Recoverable damage | Good for |
|---|---|---|
| L | about 7% | Screens or large, clean prints; lots of content |
| M (default) | about 15% | Most prints — flyers, business cards, posters |
| Q | about 25% | Warehouse and factory labels that may get scratched or dirty |
| H | about 30% | Outdoor or rough use, or where part may be covered |
Save resolution
Files are saved as PNG. Pick a higher quality for printing; higher quality takes a little longer.
QR codes (QR Style > Settings > Save quality)
| Save quality | Size | Time |
|---|---|---|
| Fast (default) | 300px | Instant (screen capture) |
| Normal | 600px | About 1s |
| High | 900px | About 2s |
| Best | 1200px | About 3s |

Barcodes (Barcode Settings > Save)
| Save quality | Approx. width | Use |

| Normal | about 400px | General printing |
| High | about 600px | High quality |

Input rules
Each barcode type allows specific characters and lengths. If an input doesn’t fit, the reason appears right below the field.
- For EAN-13, enter the first 12 digits and the check digit is calculated for you. If you enter 13 digits with a wrong check digit, you’ll be told.
- Fixed lengths (without check digit): EAN-13 12, EAN-8 7, UPC-A 11, UPC-E 7, EAN-5 5, EAN-2 2
- Interleaved 2 of 5 needs an even number of digits.
- Code 39 allows digits, uppercase letters, spaces and - . $ / + %. An uppercase keyboard appears.
- Codabar adds A as the start/stop character if you leave it out.
- Pharmacode takes a number from 3 to 131070.
- Numeric-only types (EAN, UPC, ITF-14, MSI, Pharmacode, POSTNET…) open a number pad.
Good to know
- Codes are saved as PNG. Vector files such as SVG or PDF aren’t supported yet.
- Codes you save are kept in the “Generated” group in history (up to 500). Saving the same code again adds to its count instead of a new entry.
- Open a saved code from history and tap Edit to restore its type, values, style and frame, then change it and create it again.
- Codes you only share aren’t kept in history.
- Saving to your gallery needs photo permission.
FAQ
- Which error correction level should I use?
- The default M is enough for most uses. For labels that may get scratched or dirty, choose Q or H — and print a bit larger, since the code gets denser.
- Which save quality is best for printing?
- Choose Print: 1800px for QR codes and about 1200px for barcodes stay sharp even when printed large.
- Can I make Data Matrix or PDF417?
- Only the healthcare (HIBC) variants are in the barcode list. Plain Data Matrix, PDF417 and Aztec aren’t available yet.
