Make branded QR codes you can edit and track

QR codes (Quick Response codes) are two-dimensional barcodes that can store information such as links, text, contact details, or files. When scanned with a smartphone camera, they instantly direct users to the intended action or destination.

Most smartphones can scan QR codes directly using the built-in camera. Simply open your camera app, point it at the QR code, and tap the notification that appears.

Replug QR codes don't expire. They keep working as long as your account is active, and that includes the Free plan. If you use up your monthly click quota, scans still open the destination; they just aren't tracked until the quota resets.

Yes. QR codes generated with Replug can be used for personal or commercial campaigns, including marketing, packaging, advertising, events, or business communications.

Static QR codes that store plain text, email addresses, or phone numbers work offline. However, codes linking to websites, apps, or files require an internet connection to open the content.

QR codes are versatile and can be used across virtually every industry. Retailers use them for product packaging and promotions, restaurants for digital menus, real estate for property listings, event organizers for ticketing, healthcare providers for patient information, education for course materials, finance for secure payments, and nonprofits for easy donations. With Replug, you can create custom QR codes tailored to your industry’s needs, making engagement simpler and more impactful.

The Free plan includes 10 QR codes for websites, short links and Bio Links, with shapes, colors and frames. Essentials raises that to 100 and adds every content type; Scale and Agency have no limit and add your logo. Every paid plan comes with a 14-day free trial.

QR codes have many benefits, but mainly, they make it easy to connect offline audiences with online experiences. They reduce friction by providing one-tap access to websites, apps, payments, and promotions, boosting engagement and conversions.

A QR code generator is an online tool that lets you create custom QR codes for different purposes, such as sharing websites, social profiles, contact details, or files.

A dynamic QR code points to a short link instead of straight to the final page, so every scan can be counted and the destination can change after the code is printed. Every QR code you make with Replug is dynamic; editing the destination is on Scale and Agency.

Make sure the QR code is clear, large enough to be scanned, and not distorted. If it’s a dynamic QR code, check that the destination link is active. Always test your code on multiple devices before printing.

A QR code is only as safe as the page it opens. Replug serves every code's short link over HTTPS and checks new links against Google Safe Browsing, PhishTank and VirusTotal. When you scan someone else's code, check the link your camera previews before you open it.

Many free QR tools make static codes you can't track or change. With Replug every code is dynamic and tracked: you start from 24 templates, add your own colors, frames and, on Scale and Agency, your logo, and you can retarget the people who scan. Your QR codes also sit next to your short links and Bio Links, with the same analytics, domains and team workspaces.

Yes. Start from one of 24 templates or from scratch, then change the colors, dot shapes, corners and frame to match your brand.

For print, a QR code should generally be at least 2 x 2 cm (0.8 x 0.8 inches) to scan reliably. Larger sizes are recommended for posters, billboards, or areas where users scan from a distance.

Yes, on Scale and Agency. Upload your logo or icon and Replug places it in the center of the code, so people can see who it's from before they scan.

Not if you keep strong contrast between the code and its background and leave the three corner squares clear. Dark codes on light backgrounds scan most reliably. Test your design on a couple of phones before you print.

No. Traditional QR codes are black and white, but generators like Replug let you create full-color designs with custom shapes, frames and logos.

Absolutely. You can generate multiple QR codes pointing to the same destination, each with different colors, logos, or layouts. This allows you to test designs across campaigns and platforms.

Make sure your QR code is high-resolution (SVG or PDF work best), keeps good contrast between background and foreground, and is printed at least 2 x 2 cm for easy scanning. Always test before mass printing.

Yes. By generating unique dynamic QR codes for print vs. digital campaigns, you can separate and analyze scan data to measure which medium drives more engagement.

Yes, but it’s best to avoid overly shiny finishes since reflections may interfere with scanning. Matte or semi-gloss finishes are more reliable for print campaigns.

Yes. Most modern smartphones have built-in QR code scanning through the camera app, so no additional app is required. Older devices may need a third-party scanning app. You can easily scan a QR code on an iPhone and Android through the camera.

QR codes can be printed on packaging, posters, business cards, brochures, or displayed digitally in presentations, emails, websites, or social media campaigns.

For print materials, use a minimum of 300 DPI. Vector formats like SVG or PDF are ideal because they scale without losing clarity.
