Troubleshooting
Fix the scan before you change the design.
Start here when the QR opens inconsistently, fails on one device, or seems fine on screen but breaks in the wild.
Open scan fix guideSupport hub
Get unstuck fast, then move into the right QR path.
Use help when the problem is reliability, print readiness, or setup uncertainty. Use the product hub when you already know what QR you need to build.
Fast paths
Open the support path that fits the job.
These are the three support flows most people actually need first, instead of a flat FAQ dump.
Print & export
Decide size, format, and contrast before production.
Use the print path when the QR is headed to cards, packaging, menus, or anything that needs to hold up in physical space.
Open print sizing guideSetups
Open the right QR path for the job, not just the nearest generator.
Best for merchant menus, WhatsApp support, redirect QR, and template-specific help where the destination and rollout matter.
Open QR hubHow to work in QRFlow
Keep the workflow short: decide, test, then export.
The help page should get you back into action quickly, not trap you inside support content.
Choose the path first
If the problem is scan reliability, go to guides. If the job is to create something specific, open the generator hub.
Test on a real phone
Check the final QR in the environment it will actually live in before you export or print.
Export the right format
Use SVG for print layouts and PNG when you just need a fast share-ready asset.
Utility tools
Keep calculators, scanning, and bulk actions out of the help flow.
Support content and utility tools serve different jobs. The tool library now lives on its own page.
FAQ
Common questions, without the clutter.
Keep the answers short, then jump into the right guide or generator only when you need more depth.
How do I generate a WiFi QR that works on iPhone and Android?
Use the WiFi template, keep SSID and password exact, and retest if you have special characters. The format details matter more than the styling.
Read the WiFi format guide →What QR size should I print for a business card, menu, or poster?
For business cards, start around 20–25mm. Larger signage depends on viewing distance, quiet zone, and contrast, not size alone.
See the sizing guide →Which download format should I use: SVG or PNG?
Use SVG for sharp print output at any size. Use PNG when you need a fixed bitmap for chat, docs, or a quick upload target.
Compare SVG vs PNG →How do I build a merchant QR for menus, support, or reviews?
Use URL for menus and review flows, WhatsApp Business for support, and Redirect QR when you need to change the destination later without reprinting.
Open the QR hub →Topic hubs
When one answer is not enough, move sideways into a topic.
Use topic hubs when you need grouped generators, guides, and rollout advice around the same business problem.
