Introduction
QR codes are everywhere — restaurant menus, business cards, event tickets, WiFi networks. Creating them should be simple, free, and private. Most online QR generators process your data on their servers, which means your WiFi passwords, contact details, and URLs pass through third-party infrastructure. The AllTools QR Code Generator works differently: it generates QR codes entirely in your browser using JavaScript. Your data never leaves your device.
What You’ll Need
Just a modern web browser — Chrome, Firefox, Safari, or Edge. No software installation, no account creation, no email address. Works on desktop, tablet, and phone.
Step-by-Step Guide
1. Open the QR Code Generator
Navigate to the AllTools QR Code Generator. The tool loads instantly with no sign-up required.
2. Choose Your QR Code Type
Select from preset templates at the top of the tool:
- URL — Enter any web address to create a scannable link
- WiFi — Enter your network name (SSID), password, and encryption type (WPA/WEP/None). Anyone who scans this QR code connects to your WiFi instantly without typing the password
- vCard — Enter a name, phone number, and email to create a contact card. Scanning adds the contact directly to the phone’s address book
- SMS — Pre-fill a text message to a specific phone number
- Email — Create a QR code that opens an email compose window with a pre-filled address
- Phone — Generate a tap-to-call QR code
3. Customize Your QR Code
After entering your data, customize the appearance:
- Colors — Change the foreground and background colors to match your brand. Maintain strong contrast for reliable scanning
- Size — Adjust from 128px (small, for digital use) to 512px (large, for print materials)
- Error Correction — Choose from L (7%), M (15%), Q (25%), or H (30%). Higher correction allows the QR to remain scannable even if partially damaged or obscured by a logo
- Logo Overlay — Upload any image as a center logo. The tool automatically uses high error correction to ensure scannability
4. Download Your QR Code
Download in your preferred format:
- PNG — Raster format, best for web use and digital sharing
- SVG — Vector format, scales to any size without quality loss, ideal for print
- WebP — Modern format with excellent compression
5. Use Batch Mode for Multiple QR Codes
Need several QR codes at once? Switch to batch mode and paste one URL or text per line. Each generates its own downloadable QR code — perfect for inventory labels, event badges, or product packaging.
QR Code Use Cases for Business
Restaurant menus
Replace paper menus with QR codes on tables. Customers scan and see the menu on their phone. Update the menu by changing the URL destination — the QR code stays the same. Print QR codes on table tents, stickers, or directly on the table surface. Use SVG format for crisp printing at any size.
Product packaging and labels
Add QR codes to packaging that link to product manuals, warranty registration, ingredient lists, or assembly instructions. This keeps packaging clean while providing detailed information digitally. Generate codes for each product SKU and print at label size.
Event management
Create QR codes for event tickets (link to ticket details), conference badges (vCard with attendee info), session schedules, venue maps, and feedback forms. The batch mode handles generating codes for all attendees or sessions at once.
Real estate
Property listings with QR codes on yard signs let potential buyers scan for full listing details, photo galleries, virtual tours, and agent contact information. Generate a URL QR code for each listing and include it on all physical materials.
Education
Teachers create QR codes linking to homework assignments, reading materials, class resources, and video lectures. Students scan with their phones instead of typing long URLs. WiFi QR codes in classrooms give students instant network access.

AllTools generates static QR codes — the data is encoded directly in the image and never expires. Paid services offer dynamic QR codes (which redirect through their servers and can be updated) but charge monthly fees and track scans.
FAQ
Do QR codes created here expire?
No. AllTools generates static QR codes that encode data directly in the image pattern. They work forever with no dependency on any server or subscription. This is different from dynamic QR codes (offered by paid services) which route through a server and can expire if you stop paying.
Can I create a QR code for my WiFi password?
Yes. Select the WiFi preset, enter your SSID, password, and encryption type. The QR code is generated entirely in your browser — your WiFi password never leaves your device. This is safer than cloud-based generators where your password is sent to their servers.
What size should my QR code be for printing?
The minimum scannable size is about 2cm x 2cm (0.8 inches) for scanning from close range. For posters viewed from 1-2 meters, use at least 10cm x 10cm. For billboards, the QR code width should be 1/10th of the expected scanning distance. Download as SVG for the best print quality — it scales to any size without pixelation.
Can I add my company logo to the QR code?
Yes. Upload any image as a logo overlay. The tool automatically increases error correction to Level H (30% recovery), which allows up to 30% of the QR code area to be obscured while remaining scannable. Keep your logo small (10-15% of the area) for reliable scanning.
What’s the difference between this guide and the WiFi/vCard QR guide?
This guide covers the practical workflow of creating QR codes and business use cases. The QR Codes for WiFi, vCards, and URLs guide provides detailed technical information about each QR code type, error correction levels, size calculations, and format-specific encoding details.
Should I use PNG or SVG format?
Use PNG for digital sharing (websites, emails, social media, documents). Use SVG for print materials (business cards, flyers, posters, packaging) because SVG is a vector format that scales to any size without quality loss. Use WebP when you need the smallest file size for web use.
