Everything you always wanted to know about QR Codes. Frequently asked questions for newcomers, possibilities, curiosities, tips and tricks.
QR codes are secure based on use; risks include phishing and tampering. Enhance security with HTTPS URLs and by scanning only trusted sources.
QR codes can store up to 7,089 numeric characters, 4,296 alphanumeric, 2,953 bytes, or 1,817 Kanji characters, with capacity depending on the version and error correction level.
Test your QR code on multiple devices, ensure it's visible and properly sized, secure the URL, and consider accessibility and legal compliance.
Static QR Codes work without an internet connection. Dynamic QR Codes contain a short URL and they require an internet connection in order to show its contents
EPS QR Codes need longer to render; they are bigger in file size and they do not support gradients in true vector format. Please use the PDF or SVG format instead.
The more designer elements you add to the QR Code, the more difficult it becomes to read. Remove or resize the logo and provide enough contrast.
Check if your account is active or if you have an open invoice. You might have exceeded the scan limit; the target URL is offline, or you deleted the QR Code.
Provide enough contrast · Mind the quiet zone around the QR Code · Print QR Codes in scalable vector format · Watch the minimum size · Do not exceed the maximum size of a logo in a QR Code
If you create a dynamic QR Code a shortened URL in the QR Code will be used, so fewer characters must be encoded and the QR Code will be easier to scan.
Yes, this is possible. For example, you can subsequently convert a simple dynamic QR code into a PDF QR Code, a Multilanguage QR Code, an App Download QR Code.
You can change the target URL even if the QR code has already been printed. Login into your account, edit the URL in your dashboard and set the new destination.
Static QR Codes created with our service never expire. Dynamic QR Codes in free accounts do not expire if they are scanned less than 100 times per day.
No, we do not generate micro QR Codes from our platform. Micro QR Codes were an initiative of Denso Wave intented to improve the performance of small QR Codes.
When you want to deactivate or pause a QR Code you can delete the QR Code or change the target URL to redirect the user to another landing page instead.
When scanning a QR code the user is either being linked to your website directly (static QR Code) or he is redirected through a tracking URL (dynamic QR Code).
You can view the QR Codes in EPS format in Adobe Illustrator or with the free EPS Viewer software.
QR codes can store up to 4192 characters, EAN codes can only store up to 13 digits. Smartphones read QR codes directly with the camera without a special app.
Decode the QR Code first. Dynamic QR Codes have mostly shortened URLs encoded and therefor they are less crowded and they are smaller than static QR Codes.
We do not offer unlimited creation of QR Codes under a single account both for technical and commercial reasons. We can of course create a custom plan for you.
No. The beauty of vector graphic is that you can make them as big as you want without blurring the QR Code, because only polygons are saved and not pixels.
Yes, QR Codes created on our website can be used free of charge and commercially. You can create as many QR codes as you want and they do not expire.
Yes. You can download all QR Codes in various scale-able vector formats like eps, pdf or svg. This ensures that the QR Codes scale as big as you want.
A QR code is a barcode that can contain any text up to 4096 characters long and can be read by a smartphone camera to link a user to a website or video.
A static QR Code has the target URL directly encoded and will never expire. You cannot change the target URL once printed nor track who scanned your QR Codes.
No. You cannot change a static QR Code into a dynamic QR Code because the URL of a static QR Code is encoded in the QR Code and therefore cannot be changed.
In general, yes. It depends on the error correction level, that is set when creating a QR Code. The higher the level, the more of the QR code can be damaged.
Every QR Code Generator uses different algorithms and also different encodings. Another possibility are different error correction levels (L, M, Q or H).
Apple iPhones already display the domain of the URL encoded in the QR Code when scanning. To preview the whole URL use a third party QR Code Reader App.
We recommend a minimum size of 2 x 2 cm for a QR Code. However, you must consider the scanning distance and the number of charactars encoded in the QR Code.
Yes, but it depends if the shortened URL in your QR Code contains the domain of the other website or your own domain.
Check if the target URL is online and displaying the correct content. Verify your QR Codes target URL. If URL was altered, change the password of your account.
If you have deleted a QR Code you can either recreate it using the same short URL or you can restore it from your log section on the account settings.
