We at OTRVO think that making QR codes should be quick, simple, and totally private. OTRVO is for you whether you're a student sharing a project, a teacher giving out learning materials, a business owner advertising services, or just someone who needs a quick code.
The program only works in your browser, so your data never leaves your device. There are no ads, no need to sign up, and no hidden fees at all. We don't keep, track, or share any information, so your privacy is always safe.
You can make a lot of other QR codes using OTRVO, like links, Wi-Fi passwords, vCards with contact information, emails, phone numbers, and calendar events. You can change the size, margin, and level of error correction, and then download your code in high-quality PNG or SVG files.
We are always adding new features to OTRVO, such as dynamic QR codes, scan analytics, and batch production. It will always be free and safe.
