Frequently Asked Questions
What is error correction in QR codes?
Error correction allows QR codes to be readable even when partially damaged or obscured. Higher levels allow for more damage tolerance but create denser codes.
Which file format should I choose?
Choose PNG for web use, JPEG for small file sizes, or SVG for perfect scaling at any size (ideal for printing).
Are the generated QR codes free for commercial use?
Yes! All QR codes generated are free for both personal and commercial use with no restrictions.
What's the maximum text length for a QR code?
QR codes can store up to 4,296 characters of text, including URLs, plain text, and other data types.
Can I add my logo to the Thinkforu.org QR code?
Yes! You can upload your logo image and adjust its size. For best results, use a transparent PNG file and keep the logo size under 30% to ensure the QR code remains scannable.
What is the Quiet Zone?
The Quiet Zone is the margin around your QR code. It's important to have sufficient margin (usually 1-4 blocks) to ensure proper scanning. More margin may be needed for busy backgrounds.
