QR Code Generator

Generate QR codes from text, URL or data.

How to Use QR Code Generator

1

Choose the data type: plain text, a URL, Wi-Fi credentials, a vCard contact, or an email link.

2

Fill in the fields for that type and pick an error correction level of L, M, Q, or H.

3

Set the module size in pixels and the quiet zone margin, then click the "Process" button.

4

Download as PNG for immediate use or SVG for crisp scaling, and test-scan it with a phone.

Features

Encodes text, links, Wi-Fi logins, vCards, email addresses, and phone numbers
Four error correction levels, so a code with a logo still scans reliably
Adjustable module size and quiet zone so the code prints at any resolution
Download as PNG for immediate use or SVG for lossless scaling
Instant preview with the encoded character count so you know the capacity
No watermark, no sign-up, and encoding happens in your browser

Frequently Asked Questions

Yes, free with no account, no watermark, and no cap on how many codes you generate. There is nothing to install and no email required to download the result.
No. The code is generated locally in your browser, so the SSID and password never leave your machine. The data is encoded into the pattern itself, which is why a printed code contains the credentials in plain sight anyway.
Use L or M for a plain code with maximum data capacity, and Q or H when the code will carry a logo, sit on a busy poster, or be printed on something that may get marked. H holds the least data but survives about 30 percent damage.
In order of likelihood: the quiet zone is missing or too small, the code is physically too small for the scanning distance, the colours have poor contrast, or it has been inverted with light modules on a dark background. Leave a margin of at least four modules and test-scan before printing.

About QR Code Generator

A QR code stores data as a grid of black and white modules, and any phone camera can read one in about a second. That makes it the shortest possible bridge between a printed object and a digital destination. This generator encodes text, links, Wi-Fi credentials, contact cards, email addresses, and phone numbers, then renders a code you can download immediately.

The two settings that matter are error correction and size. Error correction adds redundant data so the code still scans when part of it is obscured, and the levels are L at about 7 percent, M at about 15 percent, Q at about 25 percent, and H at about 30 percent. Higher levels hold less data but tolerate a logo, a sticker edge, or a scuffed print. The module size in pixels and the quiet zone around the code determine whether it scans reliably at the distance you need.

Formats matter too. Download a PNG for a slide, an email signature, or a quick test. Download an SVG for anything that will be printed or scaled, because it is a vector and stays sharp at any size. Either way, always test-scan the result with a real phone from the intended distance before you print a thousand of them.

When to Use This Tool

  • Letting guests join Wi-Fi without typing a password off a printed sign
  • Linking printed packaging, business cards, or a conference badge to a landing page
  • Adding a scannable menu to a restaurant table card
  • Sharing a vCard at an event instead of reading out a phone number
  • Generating a QR code for an invoice or ticket that opens a payment page
