Frequently asked questions
How does error correction level affect the QR code?
Higher levels (Q, H) make the code readable even when partially damaged or covered by a logo, at the cost of denser modules. Use L or M for clean digital displays and H for printed codes that may get scratched.
What is the maximum amount of data I can encode?
QR codes can hold up to about 4,296 alphanumeric characters or 2,953 bytes. ConverterUp picks the smallest version that fits your data; for long URLs, consider a URL shortener to keep the code readable.
Are the QR codes I generate tracked?
No. Codes are rendered entirely client-side and never sent to a server. ConverterUp does not insert tracking redirects, so the URL you scan is exactly the URL you typed.
Which output formats are available?
PNG is the default and works for both web and print. SVG export is supported for vector use cases such as logo overlays and large posters where quality must scale without pixelation.
