QR code
Best for URLs, messages, Wi-Fi credentials, contact details, and richer data that phones scan quickly.
Code Tools
Create QR codes and barcodes instantly.
Enter your content, switch formats, tune the styling, and export clean PNG or SVG assets in a few clicks. Generation happens in your browser, so your content is not uploaded to HelloAI just to make the code image.
Browser-side code creation
One workspace for scan-ready assets
Switch between QR and barcode output without leaving the page.
QR code mode works well for links, text, Wi-Fi credentials, and contact info.
320 px output
Choose more redundancy when the code may be printed small or used in rough conditions.
CODE128 is the most flexible option for mixed letters and numbers.
8 px quiet zone
Use a dark, high-contrast color for reliable scanning.
A light background usually scans best.
What each format is good for
Choose the format that matches how the code will be scanned, printed, or shared.
CODE128
Great general-purpose barcode format for text, IDs, internal labels, and mixed letters and numbers.
EAN-13 / UPC
Use these retail-oriented formats for product numbers that need a familiar checkout-style barcode.
ITF-14
Useful for carton or logistics labeling where fixed-length numeric packaging codes are expected.
Generator FAQ
Can I paste a URL directly?
Yes. URLs work well in QR mode and are one of the most common uses for this generator.
Why does a barcode show an error?
Some barcode standards only accept certain lengths or character sets. Switch to CODE128 if you need the most flexible input format.
Should I use PNG or SVG?
Use PNG for quick sharing and SVG when you need crisp scaling for print or design work.
Can I change the colors?
Yes. Dark-on-light color combinations tend to scan most reliably, especially for camera-based scanners.
