Frequently Asked Questions

Common questions about the QRLynx free tools

Are these tools really free?

Yes. The free utilities do not require an account. Guest static bulk QR downloads include a Made with QRLynx.com watermark; signing in on any plan removes it. Saved dynamic bulk QR creation is a separate account workflow that starts on Pro.

Do you upload my files to a server?

File decoding, image compression, and PDF assembly happen in your browser. The QR scanner can keep scan history locally, and the UTM Builder can save recent source, medium, and campaign values in this browser. Saving a dynamic QR or uploading a PDF to a QR project is a separate account workflow.

Can I use these tools commercially?

Yes. You can use the free utilities for lawful personal or commercial projects. The normal QRLynx terms and acceptable-use rules still apply.

Why do you offer these for free?

The utilities help with everyday QR creation, checking, and file preparation. QRLynx also offers the Free plan for saved dynamic QR codes and scan analytics, with paid plans for larger campaigns and additional controls.

What's the difference between these tools and QRLynx Pro?

These tools handle one-off jobs such as scanning a QR, tagging a URL, or compressing an image. The Free plan already provides saved dynamic QR codes and scan analytics. Pro adds password protection, smart redirects, and dynamic bulk creation. Business adds lead capture and team workspaces; Enterprise adds eligible white-label domains.

Can I create WiFi or contact-card QR codes too?

Yes. QRLynx already has WiFi and Contact Card generators in the QR type menu. For other tool requests, email support@qrlynx.com.
