Codes that work. Made your way.
Free static QR codes and professional barcodes. No signup. Generated privately in your browser.
1. Choose your content
Generate a direct QR code for a WhatsApp conversation, review, booking, document or social profile. For file sharing, enter an existing HTTPS file link; no files are uploaded.
2. Customize
Adding a logo reduces scanning reliability. Verify using a phone before printing.
Payment codes contain the details you enter. Verify IBAN, UPI ID or wallet address with the recipient before making payments. Generating a code does not verify ownership.
Barcode content
Appearance
EAN/UPC generation does not allocate or register GS1 product identifiers.
Batch generator
One entry per line; up to 3,000 codes. Download individual SVGs as a ZIP. Print up to 240 labels per job.
Dynamic QR dashboard
Edit a destination after printing, pause a code, set expiration or a password, and review aggregate scans. To prevent phishing, destinations must be HTTPS on a domain you verify via DNS TXT.
Your browser holds a 256-bit management key. Anyone who gets it can control your codes. Export a backup before clearing browser data.
1. Verify destination domain
Add this TXT record at your DNS provider. Changes can take time to propagate. Keep the TXT proof available; this does not transfer ownership of your domain.
2. Create a managed QR
All destinations must be on the same verified domain. Language takes priority over device; fallback uses the main destination.
Create a lightweight, mobile-friendly landing page on ToolUnio. Enter 2–8 links, one per line, formatted as Label | https://your-verified-domain/path.
Every link must point to your verified HTTPS domain. No external redirects are allowed.
3. My managed codes
GS1 Digital Link QR builder
Create a standards-structured HTTPS QR for a product. Enter a legitimately assigned GTIN. This does not register or verify GS1 identifiers.
Industrial printing: precise label dimensions
Paper layout is exported through your browser's print dialog. Set scale to 100% / Actual size and turn off headers and footers. Always print a calibration sheet before barcode production.
Questions & answers
Do static QR codes expire?
No. The QR pattern itself has no expiration. Encoded websites or other destinations may later become unavailable.
Can I edit an existing printed code?
Not a static code. Editing destinations and tracking scans require dynamic redirects and a managed service.
Can I use codes commercially?
Yes, subject to applicable licensing, trademark and GS1 identifier rules.
