What you can put in a QR code
A QR code can hold more than a link. Pick the type that matches the job; Wi-Fi and contact codes are quietly the most useful beyond plain links.
Link (URL)
The most common type. It opens a web address when scanned: your shop, a single listing, a landing page or a review request. The link is baked in, so type it carefully, since a static code cannot be edited after you print it.
Plain text
Shows a short message on the phone screen with no internet needed: a note, a coupon code, a batch or lot number, or care instructions on a tag. Nothing opens, so it works fully offline.
Wi-Fi
Built from your network name, password and security type. A scan offers to connect with no password typing, which is handy in a studio, pop-up, rental or office. The password lives inside the code, so only print it where you would share the password anyway.
Contact (vCard)
Saves your name, phone, email, company and website into the phone's contacts in one tap. This is the business-card code: put it on the back of a card, a hang tag or a thank-you insert so a buyer keeps your shop's details.
Opens a new email already addressed to you, with an optional subject and message. Good for support, wholesale inquiries, or a questions-about-sizing code on packaging.
Phone
Opens the dialer with your number ready to call. Useful on a shipping insert or a market-stall sign when a buyer wants to reach you fast.
SMS
Opens a text ready to send, with an optional pre-written message, such as a keyword for a discount or a sizing reply. Good for quick opt-ins without making the buyer type anything.
Location (geo)
Opens a spot in the phone's map app from a latitude and longitude. Use it for a pop-up location, a market stall or a returns drop-off point.
Calendar event
Offers to add an event to the phone calendar: a drop date, a live sale, a restock reminder or a pop-up printed on a flyer.
App-store link
Points to your app's store page and opens the right store for the phone. Most useful when you have your own seller or brand app to promote on packaging.
How QR codes work
Static vs dynamic, and why ours is static
This tool makes static QR codes: the data is baked into the pixels, so the code is free, permanent, and works offline forever. Because there is no server in the middle, it is never tracked and cannot be edited once you print it, so check the details before you download. A dynamic code points to a redirect the provider hosts, which lets you change the destination later and count scans, but it needs an account and a paid plan, and several providers deactivate or expire free dynamic codes after a trial or stamp a watermark on them. We do static only, on purpose: nothing to sign up for, nothing to expire, no watermark.
Adding a logo without breaking the scan
QR codes carry built-in redundancy, so they still read when part of the code is covered or scuffed. There are four error-correction levels: L recovers about 7% of the code, M about 15%, Q about 25%, and H about 30%. A logo covers part of the code, so a higher level keeps it scannable, which is why the tool raises error correction to H automatically when you add one. Keep the logo small, around the center fifth rather than half, keep strong contrast, and scan-test with a couple of phones before you print.
Are QR codes free, and safe to scan?
Making a code here is free, with no account and no watermark, and it stays free because it is static: once you download the PNG or SVG it is an image you own, with no per-scan fee and no scan limit. The free codes that stop working are usually dynamic ones on a trial. As for safety, a QR code only stores data like a link or text, so it cannot install anything by itself; the risk is the destination, the same as any link, which is why most phones show the address first. Everything here runs in your browser, so your data never leaves your device.
PNG vs SVG, and printing it right
PNG is a pixel image, good for screens, social posts and small prints. SVG is a vector that stays sharp at any size, so use it for packaging, large stickers and signage, or anything headed to a print shop. Both are free with no watermark. Print the code at least about 2 by 2 cm (around 0.8 by 0.8 inches), leave a quiet-zone margin of empty space around it, and keep a dark code on a light background.
QR codes for sellers
Put a QR on packaging inserts, product labels, hang tags or a listing photo. A few that earn their space: a code that opens your size chart so buyers check fit before they buy or before they return, a code to your listing or shop, and a vCard or review-request code on a thank-you insert that turns one buyer into a repeat one. For many SKUs, generate codes in bulk from a list rather than one at a time.
One important point: a QR code is not the UPC or EAN barcode that Amazon and eBay want in the product-identifier field of a listing. Those are 1D barcodes, a different code for the listing form, which the barcode generator handles. QR is for packaging, marketing and links.
QR code generator FAQ
How do I make a QR code for free?
Choose what the code links to, enter the details, and the QR appears instantly. Add a logo and colours if you like, then download a PNG or an SVG. There is no watermark and no sign-up, and the code never expires because it is static.
Do QR codes expire?
Static QR codes, like the ones this tool makes, never expire: the data is encoded directly in the image, so it keeps working forever. Only dynamic QR codes, which route through a paid redirect service, can expire or be switched off if you stop paying.
Can I add a logo to my QR code?
Yes. Upload your logo and it is placed in the centre of the code, with the error-correction level raised automatically so the code still scans. Set the QR and background colours to match your brand, then test the result with a phone before printing.
Can I download the QR code as an SVG?
Yes. Use Download SVG for a vector file that stays crisp at any print size, which is best for packaging, signage and stickers. Download PNG gives you a raster image for screens and documents. Both are free and have no watermark.
What is the difference between static and dynamic QR codes?
A static QR code stores its data inside the code, so it is free and permanent but cannot be edited later. A dynamic QR code points to a short URL you control, so you can change the destination and track scans, but it needs a paid service. This tool makes static codes.
Can I make a Wi-Fi QR code?
Yes. Choose the Wi-Fi type, enter your network name, password and security type, and the code lets anyone connect by scanning, no typing the password. It is a popular code for cafes, rentals and offices. Print it where guests can reach it.
Which QR code generator is free forever?
A static QR generator is free forever, because the finished code is just an image you own with the data baked in. This tool is static, so there is no account, no per-scan fee and nothing to expire. The free tools that stop working are usually dynamic codes on a trial.
Is this QR code generator safe to use?
Yes. A QR code only stores data like a link or text, so it cannot install anything on its own; the risk is the destination, the same as any link, and most phones show the address before opening it. Generating a code here is private too, since everything runs in your browser and nothing is uploaded.
Does this QR code generator add a watermark?
No. The PNG and SVG download clean, with no watermark and no logo of ours, so the only branding on the code is yours.
Do I need to sign up or create an account?
No. There is no sign-up and no login. Pick a type, fill in the details, and download the code.
Can I track how many people scan my QR code?
Not with a static code. Scan tracking needs a dynamic code that routes through a hosted redirect, which is a paid feature on a separate service. This tool makes static codes that work forever but are not tracked.
Is it free to use these QR codes commercially?
Yes. The codes are free to use commercially, on packaging, products, signage and marketing, with no licence fee.
How do I make a QR code that links to my size chart?
Choose the link type and paste the web address of your size chart, then download the code and print it on the packaging or insert. Buyers scan to check the fit before they buy, which is one of the most useful seller codes. Build a free Size Chart with Sizely if you need one to link to.
Make a scan-for-size-chart code
Build a free Item Chart for a single product, or a Size Chart for your whole shop with Sizely, then drop a QR on your packaging that opens it. Buyers check the fit before they buy, and send fewer items back.
