QR Code Generator

QR Code Generator encodes nine types of information — URL, text, phone number, SMS, email, geo coordinates, Wi-Fi, address book, and calendar event — into a QR code. Scan it with a phone camera to open the target page, place a call, join a Wi-Fi network, or perform whatever action matches the type.

About QR Code Generator

QR Code Generator encodes nine types of information — URL, text, phone number, SMS, email, geo coordinates, Wi-Fi, address book, and calendar event — into a QR code. Scan it with a phone camera to open the target page, place a call, join a Wi-Fi network, or perform whatever action matches the type.

Tune image size, output format (PNG / JPG / WebP / SVG), error-correction level (L / M / Q / H), foreground and background colors, quiet-zone margin, and background transparency in detail. You can also embed a logo image in the middle and copy the generated QR to the clipboard with one click.

All inputs and the logo image are processed entirely in your browser — nothing is uploaded to a server. Even QR codes containing sensitive info like internal URLs or Wi-Fi passwords are safe to make here. Runs entirely in your browser.

How to use

  1. Pick a QR code purpose from the top tabs (URL / Text / Phone / SMS / Email / Geo / Wi-Fi / Address book / Event).
  2. Enter the value for the chosen purpose (URL starting with https://, Wi-Fi SSID and password, etc.).
  3. Watch the preview while adjusting image size, output format, color, margin, and error-correction level.
  4. Optionally load a logo image (up to 2 MB / PNG / JPG / WebP / SVG) and set its size ratio and whether to draw a white mask behind it.
  5. Click "Download" to save as PNG / JPG / WebP / SVG, or "Copy" to put it on your clipboard.

Use cases

  • Marketers and shop operators putting URL QR codes on store displays, trade shows, business cards, or flyers to drive landing-page visits.
  • Restaurants, hotels, and coworking spaces sharing Wi-Fi SSID and password to visitors via QR.
  • Individuals and salespeople printing personal contacts (address-book QR) on business cards.
  • Event organizers distributing calendar-event QR codes for date and venue info.
  • Support owners placing phone or SMS QR codes for one-tap inquiry flows.

Notes

  • Embedding a logo too large for the error correction can make the QR unreadable. Use error-correction level "H" for logo embedding.
  • Background transparency is only honored for PNG / WebP; JPG and SVG ignore it.
  • The "Copy" button always copies a PNG to the clipboard (regardless of the chosen output format).
  • Logo uploads are limited to 2 MB. Compress or resize beforehand if your file is larger.
  • QR codes for official payment / authentication purposes (invoices, tickets, gate access) must follow the issuing service's spec (including encryption). This tool is for generic information embedding.

FAQ

Is the input sent to a server?
No. Generation happens entirely in your browser, so QR codes containing sensitive info like internal URLs or Wi-Fi passwords are safe to make here.
The logo I added makes the QR unreadable.
QR codes can recover from up to ~30% damage (level H). If a logo covers a large area, raise the error-correction level to "H". If it is still unreadable, reduce the logo size ratio or add a white mask behind the logo.
Which output format should I pick?
PNG (with transparency) for web pages and social posts, SVG for print (lossless at any scale), and WebP when minimizing image weight matters. JPG can soften edges when compressing, so PNG or WebP is preferred for standalone QR codes.
Which phones can read Wi-Fi QR codes?
iPhone (iOS 11+) and most Android devices support Wi-Fi QR in their camera apps. The phone shows a "Join Wi-Fi?" prompt and connects with one tap.
How do users open address-book or event QR codes on a phone?
Address book (vCard) opens an "Add contact" prompt in the contacts app; event (vEvent) opens an "Add to calendar" prompt in the calendar app. iOS and Android both handle these natively.
