Are dynamic codes free, and how long do they last?
Free, like everything else here. Each account can have 25 dynamic codes. Static codes are unlimited, because once you have downloaded one it does not depend on us for anything. We intend to keep the short links running indefinitely — they are pointing at physical products people have paid for, an... -
Can I put my logo in the middle of the code?
Yes — open Centre in the generator and choose Logo to upload an image, or Text badge to generate a small lettered badge. Which file you upload matters if this is going on a laser: Upload an SVG and its shapes are written into the exported SVG as real vector, so LightBurn and XCS can cut or engra... -
How big does an engraved QR code need to be?
It depends on how much data is in it, which is why the tool shows you the module size instead of a single number. As a rough guide, with a short link: About 25 mm is comfortable on most materials. Down to 15 mm can work on high-contrast material like acrylic or coated metal. A full contact card ... -
How do I create and manage dynamic codes?
Go to My QR Codes and sign in. Enter the destination address and an optional label, then hit Create. You get a short link like `mfco.app/A7K2Q`. Hit Make artwork to open the generator with that short link already filled in, then style and download it as usual. From the same page you can edit th... -
My dynamic code says "Blocked". What happened?
Every destination is checked against Google Safe Browsing when you save it, and all live codes are rechecked automatically on a regular schedule. If a destination is later flagged as hosting malware or a phishing page, we turn that code off automatically and show you why. This is not a judgement ... -
My engraved QR code will not scan. Why?
Almost always one of three things: The modules are too small. The little squares bleed into each other as the laser cuts, and the scanner can no longer resolve the grid. This is by far the most common cause. Watch the module size readout — under about 0.4 mm per module, most materials are a prob... -
What do you track when someone scans my code?
A count. That is all. We store the number of times a code has been scanned and nothing else — no IP addresses, no locations, no device details, no personal information about whoever scanned it. Automated link previewers and crawlers (Slack, WhatsApp, search engines) are filtered out so the number... -
A normal (static) QR code has the destination baked into the artwork. Once it is engraved on a tumbler or printed on a card, that address can never be changed. If the link dies, the code is dead. A dynamic code instead points at a short link we host on mfco.app. The artwork never changes, but you...

What is the QR Code Generator?
The QR Code Generator makes QR codes built for material rather than screens. It is free and unlimited with your free account, and it runs entirely in your browser — nothing you type and no logo you upload is ever sent to us. Two things make it different from the usual online generator: The SVG i... -
Which error correction level should I use?
Error correction adds redundant data so a damaged code still reads. Higher levels survive more damage but make a physically larger code for the same content. H (30%) — use this for anything engraved, etched, or on a curved surface. Fill inconsistency and material grain both eat modules. Q (25%) ... -
Which file format should I download?
SVG for anything going to a laser or cutter. It is vector, and it is sized in real millimetres so it lands in LightBurn or XCS at exactly the size you set. PNG for web, product listings, and general print. Choose 256, 512, 1024, or 2048 px. JPG when something specifically demands a JPEG. It has ...
