A QR code is just a way to turn a link, a Wi-Fi password or a payment address into something a phone camera can scan instead of someone typing a URL by hand. Most of the tools that generate them are free, but they differ in what happens after the "generate" button — whether there's a watermark, whether you need to sign up, whether you get scan analytics, and how much you can customize the look. Here are six free QR code generators actually worth using.
The short version: for the most generous free option with no signup and no watermark, KoloQR covers the widest range of code types. If privacy is the priority, LibreQR collects no data and tracks nothing. Want to know how many people actually scanned your code? QRtracer is free and includes scan analytics most free tools charge for. QR Code Generator is the best-known name with the deepest customization options. Developers embedding QR codes programmatically should look at QuickChart's open-source API instead of a manual web form. And if the QR code is specifically for a gift card or promotion, VaocherApp is built for exactly that.
1. KoloQR — best overall free generator
KoloQR is a free, browser-based QR code generator with no signup required, supporting 30+ code types — URLs, Wi-Fi, PayPal/Pix/UPI/crypto payments, social profiles, events — plus custom colors, shapes and logos, with exports in PNG, SVG, PDF and EPS and no watermark on any of them.
Pricing: Completely free, unlimited generation.
Verdict: the broadest free feature set on this list — most competitors either gate export formats, add a watermark, or require an account for the customization KoloQR gives away free. The tradeoff is that its codes are static: once printed, you can't redirect them to a new URL, and there's no scan tracking.
2. LibreQR — best for privacy
LibreQR is a free QR code generator built specifically around not tracking you — no data collection, no hidden fees, nothing beyond generating the code you asked for.
Pricing: Free, no hidden costs.
Verdict: the simplest, most trustworthy option if you'd rather not hand a QR tool your data in exchange for a free code. It doesn't try to compete on customization depth or analytics — it does one thing and stays out of your way.
3. QRtracer — best free scan analytics
QRtracer generates QR codes for free while including scan analytics and bulk generation, without running ads to pay for it — a combination most competitors put behind a paywall.
Pricing: Free, no hidden costs.
Verdict: if you actually want to know whether anyone is scanning the code you printed on a flyer or product, this is the rare free tool that tells you. It's less well-known than the bigger names, and the interface is more basic than the polished alternatives.
4. QR Code Generator — best-known name, deepest customization
QR Code Generator (qr-code-generator.com) is the long-established, widely recognized tool for creating personalized QR codes quickly, with no installation needed.
Pricing: Free with paid options; exact paid pricing isn't clearly published.
Verdict: the safe, familiar default if you just want something reliable and don't need advanced analytics. Pricing beyond the free tier isn't transparent, so if you outgrow the free plan, expect to hit a sales conversation or trial-and-error to find the right paid tier.
5. QuickChart — best for developers embedding codes programmatically
QuickChart is an open-source API that generates embeddable image charts, graphs, and QR codes — meant to be called from code rather than clicked through in a browser, with no watermark on the output.
Pricing: Pricing not clearly published; open source and self-hostable.
Verdict: the right tool when you need to generate QR codes on the fly inside an app — a ticketing system, an invoice generator — rather than making one code by hand. It's not built for someone who just wants a one-off code from a web form; direct support is limited compared to a dedicated commercial tool.
6. VaocherApp QR Code Generator — best for gift cards and promotions
VaocherApp QR Code Generator is built specifically for creating QR codes tied to gift cards, vouchers and promotions, with custom styling, colors and logos.
Pricing: Free.
Verdict: a narrower tool than the others here, but a good fit if the use case is literally a gift card or promo code rather than a generic link or Wi-Fi code. It's a small, lesser-known product, so support is limited.

For a one-off code with no strings attached, KoloQR or LibreQR will get you there in under a minute. If you need to know whether the code is actually getting scanned, QRtracer is the one free tool here that tells you. And if you're generating codes from inside your own application rather than a web form, skip the consumer tools entirely and call QuickChart's API directly.
