## QR Code On

Where a QR code goes decides whether it scans. Sizes, finishes and quiet zones for packaging, labels and printed products - and a free generator for the file.

- [Where Can You Put a QR Code?](https://koloqr.com/qr-code-on): Every page here is about the thing the code is printed on, rather than about the business printing it - the measurements, the material and the production step where codes usually die.
- [Product Packaging](https://koloqr.com/qr-code-on/product-packaging): What a code on a carton, pouch, label or bottle has to survive - sizes, finishes that kill a scan, and what the scan should open.
- [Business Cards](https://koloqr.com/qr-code-on/business-cards): 85 x 55 mm leaves room for one code and nothing else - where it goes, how small it can get, and which finishes kill it.
- [Flyers](https://koloqr.com/qr-code-on/flyers): A5, A6 and DL leaflets - what size the code needs, which corner it belongs in, and how to tell which batch produced the scans.
- [Stickers & Labels](https://koloqr.com/qr-code-on/stickers-and-labels): Die-cut stickers, jar labels and thermal roll stock - the sizes that work, and why clear labels and gloss laminate break scans.
- [Posters](https://koloqr.com/qr-code-on/posters): A3 to A0 - how big the code has to be for the distance people can actually stand at, and how high off the floor it belongs.
- [Invitations](https://koloqr.com/qr-code-on/invitations): Weddings, parties and formal invitations - where the code belongs, how small it can go, and which finishes and overlays block it.
- [Menus & Table Tents](https://koloqr.com/qr-code-on/menus-and-table-tents): The code sits 40 cm from a seated guest in dim light on a laminated card - what that costs in size, finish and page speed.
- [Banners](https://koloqr.com/qr-code-on/banners): Roll-ups, exhibition and outdoor banners - the size the distance demands, the height that works, and why mesh and wind break scans.
- [Brochures](https://koloqr.com/qr-code-on/brochures): Tri-folds, bi-folds and stitched booklets - which panel the code belongs on, why the fold is fatal, and how to track panels separately.
- [Tickets](https://koloqr.com/qr-code-on/tickets): Entry codes and information codes on the same stub - how to separate them, size them, and stop thermal stock fading before the door opens.
- [Vehicles](https://koloqr.com/qr-code-on/vehicles): Vans, cars and fleet livery - the size a code needs at the kerb, and the part of the bodywork where it survives rivets, seams and road film.
- [T-Shirts](https://koloqr.com/qr-code-on/t-shirts): Chest and back prints - the size woven fabric actually holds, which print method keeps the module edges, and what survives twenty washes.
- [Billboards](https://koloqr.com/qr-code-on/billboards): 48-sheets, 6-sheets and building wraps - what the distance arithmetic asks for at that scale, and the placements where it argues against a code entirely.

## Guides

Practical guides to QR codes: how they compare with barcodes, how much they hold, what breaks a scan, and how to choose the right format for print.

- [Guides to QR Codes That Actually Work](https://koloqr.com/guides): The details that decide whether a QR code does its job are the ones nobody writes down: what it can hold, how big it has to be for the distance it's read from, and where a different symbol would serve you better. These guides answer one of those questions each.
- [QR Code vs Barcode: How They Differ and When to Use Each](https://koloqr.com/guides/qr-code-vs-barcode): Capacity, scanning hardware, print size, damage tolerance and cost - a side-by-side comparison of linear barcodes and QR codes, with a rule for choosing.
- [QR Code Error Correction: How L, M, Q and H Actually Work](https://koloqr.com/guides/qr-code-error-correction): What each error correction level recovers, how much data it costs, how large a logo it allows, and why raising the level can make a printed code harder to scan.
- [QR Code Resolution: How Many Pixels and How Much DPI a QR Code Actually Needs](https://koloqr.com/guides/qr-code-resolution): The print formula, the pixel ceilings of common PNG sizes, module size in millimetres, and the resolution mistakes that make a printed QR code stop scanning.
- [How to Copy a QR Code Into Figma as Editable Vectors](https://koloqr.com/guides/copy-qr-code-to-figma): The clipboard SVG route into Figma, what the pasted layers actually contain, which edits keep the code scannable, and how the workflow compares with a Figma plugin.
- [QR Code Minimum Size for Print: How Small a Code Can Go Before It Stops Scanning](https://koloqr.com/guides/qr-code-minimum-size-for-print): The 2 cm floor and where it comes from, the distance rule, minimum sizes for cards, menus, packaging and posters, and how URL length pushes the minimum up.
- [SVG vs PNG vs PDF vs EPS: Which QR Code File Goes Where](https://koloqr.com/guides/qr-code-svg-vs-png): The one-line rule for each format, what a KoloQR PNG, SVG, PDF and EPS file actually contains, where each one gets refused, and how to convert between them without damaging the code.
- [Matte or Gloss: How the Finish Decides Whether a Printed QR Code Scans](https://koloqr.com/guides/matte-vs-gloss-qr-code-printing): Why gloss fails under a downlight and matte does not, the finish to specify for each print job, what coated and uncoated stock do to the modules, and the CMYK build to hand a printer.
- [QR Code Quiet Zone: The Empty Margin That Decides Whether a Code Is Found](https://koloqr.com/guides/qr-code-quiet-zone): Why a scanner needs empty space around a QR code, what four modules works out to in millimetres, the layout habits that quietly remove it, and how to measure what a file actually carries.
- [Why a QR Code Is Not Scanning, and How to Tell Which Fault You Have](https://koloqr.com/guides/why-qr-code-is-not-scanning): The three ways a QR code fails - never detected, read badly, or read perfectly into a broken destination - and how the symptom tells you which one you have before you measure anything.
- [QR Code Finder Patterns: Why There Are Squares in the Corners of Every QR Code](https://koloqr.com/guides/qr-code-finder-patterns): What the three corner squares in a QR code actually do, why the fourth corner is empty, and how much of a symbol is structure rather than the data you put in it.
- [QR Code Capacity: How Much Data Fits, by Symbol Version and Encoding Mode](https://koloqr.com/guides/qr-code-capacity): The capacity of every QR code version in all four encoding modes, why the same URL fits in a smaller code in capitals, and how payload length decides the smallest size a code can be printed at.
- [How to Scan a QR Code With a Phone, a Screenshot, or a Second Device](https://koloqr.com/guides/how-to-scan-a-qr-code): The camera does it on both platforms, but the awkward cases - a screenshot, a code on the phone you are holding, a login code - each need a different move.
- [Nine Things to Check Before a QR Code Goes to Print](https://koloqr.com/guides/qr-code-print-checklist): The nine checks between a QR code file and a print run that works, each with the number it has to clear and the page that explains why.
- [Do QR Codes Expire? The Pattern Never Does](https://koloqr.com/guides/do-qr-codes-expire): The pattern never expires, and four things behind it do. Which one failed, how to tell them apart, and which of them you can fix without reprinting.
- [Static or Dynamic? Decide It Before Anything Is Printed](https://koloqr.com/guides/static-vs-dynamic-qr-codes): The difference is where the destination lives, and price, analytics and every failure mode follow from it. Four questions that settle which one to print.

## Blog

Where QR codes come from, what actually breaks them in the wild, and what changes in the KoloQR generator - posted when there's something worth saying.

- [Notes From Building a QR Code Generator](https://koloqr.com/blog): The guides answer the question you arrived with. This is the rest: where the format came from, what we measured when we weren't sure, and what changed in the generator and why. Posted when there's something worth saying rather than on a schedule.
- [Best Free QR Code Generators in 2026](https://koloqr.com/blog/best-free-qr-code-generators-2026): Free resolves to three different arrangements - a code you keep, a code you rent, and a trial that ends - and the vendor's pricing page is rarely where the difference is stated.
- [A Round QR Code Is a Square QR Code in a Costume](https://koloqr.com/blog/do-custom-qr-shapes-scan): Shaped codes scan, because the shape never touches the data. What a shape actually costs is width: a triangular code needs a base about 2.6 times the width of the matrix inside it.
- [A QR Code Decodes at 1.2:1. Do Not Design Anywhere Near It](https://koloqr.com/blog/minimum-contrast-scan-test): The contrast floor for a QR code is around 1.24:1, and that is not remotely where you should design. What eats the margin is the paper, the light and the lens - not the phone.
- [A QR Code in a Video Ad Needs a Third of the Screen. It Gets a Corner](https://koloqr.com/blog/qr-codes-in-video-ads): A QR code in a video ad has to be a quarter to a third of the screen height before a phone on the sofa can read it. Almost every one you have seen is a corner logo, and we measured what happens to those.
- [The Sign Lasts Ten Years. The Subscription Renews Monthly.](https://koloqr.com/blog/dynamic-qr-code-subscription): The pattern you print contains the provider's domain, not yours - which is why a lapsed plan turns a sign into a dead object, and why a domain you own is the only portable version of a dynamic code.
- [Seven Flowcode Alternatives and What Each Replaces](https://koloqr.com/blog/flowcode-alternatives): Flowcode's free plan stops at 2 codes and 500 scans, and the first paid step is $25 a month - here is what seven alternatives cost, and why none of them can rescue a code that is already printed.
- [QRCode Monkey Is Genuinely Free, and Its PDF Is Not Vector](https://koloqr.com/blog/is-qr-code-monkey-really-free): QRCode Monkey's free tier is real, and two things in it are not what they look like - the upsell inside the editor, and a PDF export that turns out to be a picture of a QR code rather than a vector one.
- [Fifty QR Code Colour Pairs, and Which of Them Survive Print](https://koloqr.com/blog/fifty-qr-colour-pairs): Fifty QR code colour pairs with the contrast ratio computed for each, grouped by whether they clear the print threshold, the screen one, or neither.
- [ME-QR Is Free, and the Person Scanning Pays for It](https://koloqr.com/blog/is-me-qr-free): ME-QR's free tier is real and unusually generous, and the price is paid by the person scanning your code. We read the pricing endpoint, the FAQ and the terms on 29 August 2026 and wrote down what free actually means.
- [QRFY Is Free for Static Codes, and Most of Its Types Are Not Static](https://koloqr.com/blog/is-qrfy-free): QRFY's free static codes are real, and two things around them are easy to miss - the account the download button asks for, and the fact that the Website tile most people start from is a dynamic code on a seven-day clock.
- [QR Tiger Is Free Twice Over, and Only One of Them Is Really Free](https://koloqr.com/blog/is-qr-tiger-free): QR Tiger's free plan is two different offers wearing one label: unlimited static codes that cost nothing and outlive the company, and three dynamic codes capped at 500 scans that are paid for by the person holding the phone.
- [Unitag's Free QR Codes Stop Working After 100 Scans](https://koloqr.com/blog/is-unitag-free): Unitag's free QR code generator is free to use and free to download, and the code it produces is switched off after 100 scans. That is Unitag's own published rule, and it sits two clicks from a page advertising lifetime validity.

- [KoloQR vs Scanova](https://koloqr.com/compare/koloqr-vs-scanova): A free open-source design tool for static QR codes, compared with a subscription platform for editable, tracked QR codes. The deciding question is whether the code needs to keep working after you stop paying.
- [KoloQR vs Uniqode](https://koloqr.com/compare/koloqr-vs-uniqode): A free open-source design tool for static QR codes, compared with an enterprise QR platform built on dynamic codes, scan analytics and team controls.

- [KoloQR vs Unitag](https://koloqr.com/compare/koloqr-vs-unitag): A free open-source generator that hands you a print-ready vector file, compared with a European QR platform whose free download is a 300-pixel PNG limited to 100 scans.

- [KoloQR vs QR Batch](https://koloqr.com/compare/koloqr-vs-qr-batch): A free design tool that makes one QR code at a time, compared with a paid production line that turns a spreadsheet into thousands of them.

- [KoloQR vs QR Planet](https://koloqr.com/compare/koloqr-vs-qr-planet): Two free generators that both hand over a print-ready vector file without an account - the rarest thing in this collection. The decision comes down to whether you need a code that isn't square, or a PDF already separated into CMYK.
- [KoloQR vs Bitly](https://koloqr.com/compare/koloqr-vs-bitly): A free open-source generator that hands you a finished vector file, compared with the best-known link platform, whose QR code is a bit.ly short link drawn as a symbol. The deciding question is whether your printed code should depend on someone else's server.
- [KoloQR vs Canva](https://koloqr.com/compare/koloqr-vs-canva): A design platform where the QR code is one app among thousands of templates, compared with a generator that makes nothing but the code and hands over the vector file.

- [KoloQR vs QR Code Generator](https://koloqr.com/compare/koloqr-vs-qr-code-generator): A free open-source generator that hands you a print-ready vector file, compared with qr-code-generator.com, the Bitly-owned platform whose free static codes never expire but download as a JPG.

- [KoloQR vs Pageloot](https://koloqr.com/compare/koloqr-vs-pageloot): A free design tool with no account against a subscription QR platform with a free front door. The question is not which is better but whether you need a file you keep forever or a code you can re-point after it is printed.
- [KoloQR vs Adobe Express](https://koloqr.com/compare/koloqr-vs-adobe-express): A dedicated QR code generator against a full design application with a QR code quick action bolted on. The question is not which is better software - it is whether the code or the layout around it is the part you actually need help with.
- [KoloQR vs The QR Code Generator](https://koloqr.com/compare/koloqr-vs-the-qrcode-generator): Two generators that both start free in the browser, with the line drawn in a different place.
