How can we help?

No. You can create and download static QR codes of every type without signing up. An account is needed to save codes, create dynamic QR codes or hosted pages, upload files and see analytics.

Open the generator, pick what the code should open, fill in the details, then download. The preview updates as you type and is test-scanned automatically.

No. PNG, JPG, SVG and PDF downloads are clean and free for commercial use.

Use SVG or PDF for printing (they stay sharp at any size), PNG for websites and WhatsApp, and JPG only when a tool doesn't accept PNG. The 4096 px PNG suits large prints.

In the generator, switch to Style, or open the design studio. Adding a logo raises error correction automatically.

Not necessarily. Low contrast, large logos and busy styles make codes harder to read. The live scan test warns you when our scanner can't read a design — still test the printed code with a few phones.

At least 2 × 2 cm for close-range scanning. A good rule is 1 cm of QR width per 10 cm of scanning distance — a poster read from 2 m needs about 20 cm.

Extra data that lets a damaged or partly covered code still scan. Level M (15%) is a good default; H (30%) is used automatically when you add a logo.

Any app that supports UPI QR scanning — Google Pay, PhonePe, Paytm, BHIM, Amazon Pay and most bank apps. The QR uses the standard upi://pay format.

Leave the amount empty for a counter QR that works for every bill. Set a fixed amount for a specific invoice or product. Some apps let the payer edit a pre-filled amount, and some limit QR payments to personal (non-merchant) UPI IDs.

Only your bank or UPI app (or SMS from your bank) can confirm a payment. A customer's phone screen is not proof — screenshots can be faked. This site never sees payments and never marks anything as paid because a QR was scanned.

Yes — the Bank Payment type encodes your account number and IFSC as a UPI address (account@IFSC.ifsc.npci), which most UPI apps accept. You can also create a plain-text QR with bank details for manual NEFT/IMPS transfers.

We never ask for or store UPI PINs, OTPs or bank passwords. You never need to scan a QR or enter your PIN to receive money — anyone who asks you to is attempting fraud.

A static QR stores the content directly in the image — it works forever and offline, but can't be changed. A dynamic QR stores a short link on this site that redirects to your destination, so you can change it later, pause it and track scans.

Dynamic QR codes and hosted pages depend on this service and its domain. If the server is offline or the domain lapses, printed dynamic codes stop working. Static codes are unaffected. If you self-host, keep NEXT_PUBLIC_APP_URL stable.

No — a printed static QR can't change. Create a dynamic QR and use that for new prints.

EAN-13 for retail products in most countries, UPC-A for the US and Canada, ITF-14 for cartons, and Code 128 for your own SKUs and asset tags. The barcode generator explains each format.

Products sold through retailers and marketplaces need GTINs allocated to your company by GS1. Internal numbers generated here use the restricted-circulation prefix 2 and are only for use inside your own shop or warehouse.

Allow camera access for this site in your browser (the camera icon in the address bar) and try again. Browsers only allow the camera on HTTPS. You can always upload or paste an image instead.

No. Decoding runs on your device; camera frames and images are never uploaded. Nothing opens automatically, and scanning never changes stock.

For dynamic QR codes: time of scan, device type, browser, operating system and (when the hosting platform provides it) country. Raw IP addresses are never stored — a salted, daily-rotating hash estimates unique visitors.

Yes. Visitors sending Do-Not-Track or Global Privacy Control are counted, but no device details or visitor hash are stored. Owners can also turn detailed analytics off per QR code.

No. A scan means someone opened the link. It doesn't mean they bought something or paid.

Use Forgot password on the sign-in page. A reset link is sent to your e-mail address.

Settings → Account & security → Sign out other devices. Changing your password also signs out other sessions.

Settings → Delete account. Your codes, products and files are removed, and dynamic QR codes stop working.

Paid plans are subscriptions processed by Razorpay and renew monthly or yearly until you cancel. Card and UPI details are entered on Razorpay's checkout, never on this site.

Only after Razorpay confirms the payment to our server. If you close the payment window early or the payment is still processing, your plan stays the same until the confirmation arrives.

Settings → Billing → Cancel subscription. You keep the plan until the end of the period you've paid for; Razorpay won't charge you again.

Nothing is deleted. Dynamic QR codes keep redirecting; you just can't create more than the new plan allows until you're under its limits.

Common causes: low contrast (light modules or a dark background), a logo that's too large, a missing quiet zone (the empty border), printing too small, or a glossy or curved surface. Fix the warning the editor shows, then re-test.

Paused codes can be re-enabled from Dynamic QR. A deleted code can't be restored. Codes disabled after an abuse report can't be re-enabled by the owner — contact support.

Delete codes you no longer need, or compare plans on the pricing page.
