We Tested 20 "Free" Generators
Disclosure: Published by EZQR.
We created accounts on 20 QR code generators that advertise free plans. For each, we checked: Do codes actually work long-term? Are there scan limits? Do they inject ads or watermarks? Is the "free" tier actually a trial that requires a credit card?
Most "free" generators use the word "free" to get you to create codes, then introduce limitations after you've already printed materials. That's when the real cost hits: reprinting.
The Trial Trap
Six of the 20 generators we tested advertised "free" but actually required a credit card and auto-charged after 7-14 days.
QR Code Generator (qr-code-generator.com) is the worst offender. They have 9,220+ reviews on Trustpilot with a 1.5/5 average. The most common complaint: users create "free" codes, print them on business cards or menus, then get charged $133/year when the trial ends. Cancellation requires emailing support, and refund requests are routinely denied.
QRfy advertises a "free plan" that's actually a 7-day trial requiring a credit card. No reminder email before charging. QR.io offers a 7-day trial only, and has BBB complaints for continuing to charge after cancellation.
If a "free" tool asks for your credit card, it's not free. It's a trial with auto-billing.
Scan Caps That Break Your Codes
Some generators give you free codes that work... until they hit a scan limit. Then they just stop.
QR Code Chimp caps free codes at 1,000 scans per month. Hit the limit and your codes stop resolving. Flowcode's free tier caps at 500 total scans. For a restaurant menu QR code that gets scanned 30-50 times a day, those limits hit within weeks.
The problem isn't the limit itself. It's that most users don't know the limit exists until their codes stop working. A customer scans your menu code and gets an error page. You don't know why until you check the dashboard and find out you've been capped.
Both EZQR and QRCode Monkey have no scan limits on any tier, including free.
Ad Injection: The Invisible Cost
ME-QR gives you unlimited free dynamic codes with no scan caps. Sounds perfect. The catch: they inject full-screen interstitial ads into the scan experience. Your customer scans a professional code on your table tent and sees a dating app ad before reaching your menu.
Bitly's free tier shows "suspicious link" warnings on legitimate URLs, which functions as a scare tactic to push users to paid plans. Reddit threads describe personal websites, wedding pages, and small business sites getting flagged.
These costs don't show up on a pricing page. They show up in customer experience. A QR code with an ad interstitial damages your brand in ways that are hard to measure but easy to feel.
The Real Cost: Reprinting
All of these hidden limitations share one consequence: reprinting. When your free codes stop working (trial expired, scan cap hit, service shut down), every printed material with that code is dead weight.
Business cards: $50-200 per batch. Restaurant menus: $100-500. Product packaging: $500-5,000+. Event materials: varies wildly but always more than the $5-10/mo a paid QR plan costs.
The "free" generator that costs you a reprint isn't free. It's the most expensive option.
The lesson: if you're putting a QR code on anything printed, use either a genuinely free tool (EZQR, QRCode Monkey) or a paid tool with honest pricing. Don't gamble on a trial that might expire before your print run does.
