Frequently Asked Questions (FAQ)
Is this QR Code Generator completely free?
Yes, UCDreams QR Code Generator is 100% free with no sign-up, subscriptions, watermarks, or hidden paywalls. You can generate unlimited static QR codes for commercial and personal use.
Do these QR codes ever expire or have scan limits?
No. The generated QR codes are permanent static QR codes. They directly encode your information into the matrix without redirect servers, meaning they will work forever with unlimited scans.
How does bulk QR code generation work?
Switch to the “Bulk Batch Generator” tab, paste a list of URLs/texts (one per line) or upload a CSV file, and click “Download All as ZIP”. The browser generates all QR codes locally and bundles them into a downloadable ZIP archive.
What resolution is best for printing QR codes?
For large print formats (posters, banners, product packaging), we recommend downloading in SVG vector format for infinite scaling without quality loss, or selecting 4K Ultra Resolution (4096×4096 px) PNG.
