Why choose FreeQRHub?
FreeQRHub is a fast, free QR code generator built for privacy and reliability. There’s no signup and no watermark—just clean QR codes you can download as PNG or crisp, print-ready SVG. Create codes for websites, Wi-Fi logins, text notes, app deep links, product labels, event check-ins, and more. This page also doubles as a knowledge base with best practices we’ve learned running QR campaigns for restaurants, schools, non-profits, and events.
Quick start: generate a free QR code
Paste a link or text in the box above.
Choose size, colors, and error correction (Low / Med / High / Max).
Decide whether the code should open a URL, join Wi-Fi, save a contact, start an email/SMS, trigger an app deep link, or add a calendar event. Align the target content with a single, obvious CTA on the poster/menu/business card.
2) Craft the destination
Landing pages should load in <2s, have a big headline + one action.
UTMs help you measure print performance (guide below).
Wi-Fi uses the WIFI:T:WPA;S:SSID;P:password;; string (see formats).
3) Choose size by viewing distance
Use the table below; for any signage larger than letter-size, prefer SVG.
4) Contrast & error correction
Dark foreground on light background. If you add a logo or print small, set error correction to High or Max.
5) Test before print
Scan on at least two phones (iOS + Android) indoors and outdoors (sun glare). Check the quiet zone isn’t cropped.
QR size vs viewing distance (rule-of-thumb)
Export SVG for print; PNG is fine for documents. Distances are approximate.

Smart QR uses for business, education, and events
QR codes connect offline moments to online actions. With FreeQRHub you can create scan-friendly codes that launch websites, collect feedback, or unlock downloads.
Business cards → portfolio & socialsTable tents → digital menusEvent posters → check-in, ticketsWi-Fi cards → one-tap joining
Industry playbooks
Restaurants & cafés
Menus on table tents; add UTMs by location (bar, patio, window).
Receipt QR to Google Reviews; pair with “Thanks for visiting” CTA.
Loyalty sign-up → email/SMS with first-visit coupon.
Retail & packaging
Care guides / assembly videos right on the box or hang-tag.
Check-in posters for events; volunteer sign-ups with tags.
Homework answer keys and classroom announcements.
Donation posters with QR to payment page (UTMs per venue).
Events & conferences
Booth signage linking to spec sheets and demo videos.
Lead capture forms with unique UTMs per staff badge.
Post-event survey QR at exits; offer a small incentive.
Real-world results: quick case studies
Local café: 32% more reviews in 14 days
A Sacramento café printed a 2×2 in. QR on receipts that linked straight to their Google Business review form. Using High error correction and dark-on-light contrast, they captured 87 new reviews in two weeks (+32% vs prior period), lifting their average rating from 4.3 → 4.6.
School open house: faster check-in, fewer lines
Instead of paper sign-in sheets, staff placed QR posters at the entrance that opened a simple form. Parents scanned, submitted, and walked in. Average wait per family dropped from 4:10 to 1:05. Poster exports were SVG to stay crisp at 24×24 in.
Printing tips & troubleshooting
Maintain strong contrast (dark foreground on light background).
Keep quiet-zone margins; don’t crop too close around the code.
Use High or Max error correction for small prints or when adding a logo.
Not scanning? Try this:
Increase size 20–40% and reprint.
Use a darker foreground; remove background images behind finder eyes.
Switch module shape back to Square.
Test on iOS and Android; some apps decode differently.
Provide a plain-text short URL near the QR for users without camera apps.
Pair with a clear CTA: “Scan to view menu” vs “Scan me”.
Mind contrast for low-vision users; avoid light-on-dark codes.
Place codes at reachable height and away from glare.
Privacy & safety
FreeQRHub generates QR codes entirely in your browser—your content is not uploaded. If you use ad-funded pages, you can opt for non-personalized ads at any time. Avoid encoding sensitive data (passwords, PII) in public-facing codes; for Wi-Fi, consider a guest SSID.
Use HTTPS links only.
Avoid shortening links that obscure the destination on public signage.
Rotate QR destinations if you publish them in high-traffic areas.
Glossary
Error correction (L/M/Q/H)
Built-in redundancy so codes still scan if partially damaged. Higher levels tolerate more damage but add density.
Quiet zone
The light margin around a QR; cropping it harms detection.
Module
One square “pixel” of a QR code.
Finder eyes
The three large squares that help cameras locate the code.
SVG
Vector format that stays sharp at any size—ideal for print.
Free printable templates (ready to use)
Save time with drop-in, printer-friendly layouts. Each template includes safe margins, quiet-zone guidance, and size notes for reliable scanning.
Prefer SVG? Use the generator above to export SVG and place it directly into your design app (Figma, Illustrator, Affinity).

ISO/IEC 18004 (QR Code) concepts: error correction levels and quiet zones
General print practice: 300 DPI raster or vector SVG for signage
Inclusive design: provide a short URL near the code for non-camera users
