Absolutely! Our tools are fully responsive and optimized for all devices including smartphones, tablets, and desktops. Generate codes on the go from your phone, whether you're at your warehouse, store, or event venue. The interface adapts seamlessly to any screen size.
What barcode formats do you support?
Our barcode generator supports Code-128, Code-39, Code-93, EAN-13, EAN-8, UPC-A, and UPC-E—covering virtually all common retail, inventory, and logistics needs. Each format follows industry standards to ensure compatibility with standard barcode scanners.
What types of QR codes can I create?
Our QR code generator creates codes for URLs, plain text, emails, phone numbers, SMS messages, WiFi credentials, and vCard contacts. All codes work with standard smartphone cameras and QR code reading apps without requiring special software.
What file formats can I download, and which should I use?
Download in PNG (raster) or SVG (vector) format. Use PNG for web content, social media, and standard printing (300+ DPI recommended). Choose SVG for professional printing, large format displays, or designs where you might resize the code later—SVG scales infinitely without quality loss.
Will the generated codes work with all scanners?
Yes! We use industry-standard encoding algorithms that ensure compatibility with all commercial barcode scanners and QR code readers. Barcodes follow GS1 and ISO standards, while QR codes meet ISO/IEC 18004 specifications. Test codes before mass production to verify in your specific environment.
Can I customize the appearance of barcodes and QR codes?
Yes! Customize size, colors, text display, and other visual elements while maintaining scanability. QR codes support custom colors and error correction levels. Barcodes allow size adjustment and text positioning. We recommend testing customized codes to ensure reliable scanning.
Do the generated codes expire or stop working?
No, generated codes never expire. Once created, they remain functional permanently. The files you download are yours to keep and use indefinitely. However, if a QR code links to a URL, ensure the destination website remains active—the code itself won't expire, but broken links won't work.
How do I learn more about using barcodes and QR codes effectively?
