Choose QR type
0/300 characters
Paste a full profile URL, or enter a handle (with or without @). YouTube uses /@channel format.
Host your file on Drive, Dropbox, or your site — the QR only stores the link (same as a URL QR).

Customise
PNG, JPG, SVG, and copy use this pixel size. Live preview stays the same while editing.
Square logos work best. Scan reliability uses higher error correction when a logo is present.
Generated locally — your data never leaves your browser.
What makes us different
Built for real people,
not techies.
100% private. Always.
Your WiFi passwords, contact info, and links never touch a server. QR codes are generated entirely in your browser — we don't see anything.
Instant generation
QR code updates as you type. No waiting, no "Generate" button to click repeatedly.
PNG & SVG downloads
PNG for quick sharing. SVG for print-quality output. Optional logo in the centre with stronger error correction.
QR code types
URL, WiFi, vCard, text, WhatsApp, email, phone, social profiles, PDF links
Custom colors
Match your brand with custom foreground and background colors.
Forever
No watermarks, no signups, no limits. Ever.
How it works
Three steps. Under 10 seconds.
Choose QR type
Pick URL, WiFi, vCard, WhatsApp, social, PDF link, or any other supported type from the tabs.
Enter your data
Fill in the details — URL, WiFi password, contact info. QR generates instantly.
Download
Set export size (256–2048px) for downloads, then grab PNG or SVG. The on-screen preview stays a fixed size for easy editing.
FAQ
Common questions
Is this QR code generator really free?
Yes, completely free. No signup, no watermarks, no hidden limits. We make money from non-intrusive ads.
Is my data safe? Do you store my WiFi password?
Your data never leaves your browser. All QR code generation happens locally using JavaScript. We don't see, store, or transmit anything you enter.
What types of QR codes can I create?
URL/links, WiFi credentials, vCard (digital business card), plain text, WhatsApp chat links, email with subject/body, phone numbers, social profile links (Instagram, LinkedIn, etc.), and links to hosted PDFs or documents.
Can I put my logo in the middle of the QR code?
Yes. Upload a small PNG, JPG, WebP, or SVG in the Customise panel. We bump error correction automatically so the code still scans. Keep the logo simple and leave enough quiet zone around the QR.
How does the WiFi QR code work?
When someone scans a WiFi QR code, their phone automatically offers to connect to the network — no typing the password. Works on iOS 11+ and Android 10+.
Can I customize the QR code colors?
Yes. Use the Customise panel to change the foreground (QR modules) and background colors. Keep good contrast for best scanning reliability.
Why doesn't the preview change when I pick a different export size?
The live preview stays one consistent size so you can tweak colours and shapes without the QR jumping. Small / Medium / Large / Print sets the pixel dimensions for PNG, SVG, and copy — same idea as our dedicated WiFi and WhatsApp QR pages.
What's the difference between PNG and SVG?
PNG is a raster image — great for screens and quick sharing. SVG is a vector format that scales cleanly — perfect for print. Both respect your chosen export size.
Do the QR codes expire?
No. Static QR codes (like URL, WiFi, vCard) contain the data directly in the code — they work forever without any dependency on our servers.
Does it work on mobile?
Fully. Works on Android and iOS browsers. Generate and download QR codes directly on your phone.
