Frequently Asked Questions
What is the maximum amount of text a QR code can hold?
A standard QR code can encode up to 4,296 alphanumeric characters. In practice, shorter URLs (under 100 characters) produce simpler, faster-scanning QR codes. Very long URLs or text generate dense codes that some older scanners struggle to read.
What is the difference between PNG and SVG output?
PNG is a raster image — ideal for digital sharing, emails, and screens. SVG is a vector format that scales without pixelation, making it the right choice for print materials like business cards, posters, and packaging.
Can I change the color of the QR code?
The generator produces standard black-on-white QR codes optimised for maximum scanner compatibility. Custom colors are possible in design software after export — ensure at least 70% contrast between the dark and light modules to maintain scanability.
Do QR codes expire?
QR codes generated here do not expire — they are static and encode the data directly. However, if the URL you encoded goes offline or changes, the QR code will scan correctly but lead nowhere. Dynamic QR code services let you update the destination URL without reprinting.
How do I test if a QR code works before printing it?
Scan the generated QR code with your phone's camera or a QR reader app before downloading or printing. Test on multiple devices if the code will appear on high-volume print materials. Ensure the destination URL is live and correct.
Is the QR Code Generator free to use?
Yes, the QR Code Generator on Allio Tools is completely free with no sign-up or registration required. It works directly in your browser.
How does the QR Code Generator work?
Generate QR codes for URLs, plain text, and vCard contacts in your browser — choose size and format (PNG or SVG), then download. No account, no upload, instant generation. No data is sent to a server — everything runs locally in your browser for maximum privacy and speed.
Do I need to install anything to use the QR Code Generator?
No installation needed. The QR Code Generator runs entirely in your web browser on any device — desktop, tablet, or mobile.
Is my data safe when using the QR Code Generator?
Completely safe. The QR Code Generator processes everything locally in your browser. No input data, results, or usage information is ever transmitted to or stored on any server.
Does the QR Code Generator work offline?
After the page loads for the first time, the QR Code Generator works without an internet connection for all client-side processing. Tools that fetch live external data (such as DNS or network lookups) require an active connection.
What image formats does the QR Code Generator support?
The QR Code Generator works with common image formats supported by your browser, including JPEG, PNG, WebP, and GIF. SVG support varies by tool. No format conversion plugin or driver is needed.
Does the QR Code Generator work with large image files?
Yes. The QR Code Generator processes files entirely in your browser using the Canvas API. Very large files (over 20 MB) may take a few extra seconds on older or lower-powered devices. Closing other tabs can free up memory for better performance.
Does the QR Code Generator work on all browsers?
Yes. The QR Code Generator is built with standard browser APIs and works on all modern browsers including Chrome, Firefox, Safari, and Edge — on both desktop and mobile. No plugins, extensions, or third-party software are required.
How do I save or export my results from the QR Code Generator?
Select and copy the result text to paste into any document or app. For image tools, a Download button saves the file directly to your device. Your browser's built-in screenshot function also captures results quickly. No account or login is required.
