The content of the displayed qr code is partially replaced by some asterisks.

This is normal.
To avoid screenshot problems, the correct content of the qr code is activated at download time!
Anyway, the small qr code in the upper left corner of the main GUI will always display the correct content. You can easily crosscheck doing some mobile tagging.

I’d like to use a short URL!

QRcodeLab - online qr code generator - content widgetFeel free to use a free online service like tinyURL and paste the resulting short URL in the qr code content drop-down menu.

Is it possible to manage metrics with my qr codes?

QRcodeLab - online qr code generator - content widgetFeature coming soon!
Meanwhile you can rely on one of many existing online services which provide metrics centered functionalities related with :
– branded short links
– smart (or dynamic) links
– landing page management (lead generation, survey, A/B testing, …)
– retargeting pixels
Loosely and uncomplete: Google or Facebook ads management console, Firebase Dynamic Links (Google), rebrandly, capsulink, hootsuite, prettylink, bit.ly, bl.ink, tr.im, delivr.com, tiny.cc, …
Simply paste the URL provided by your provider in the qr code content drop-down menu.
Before downloading your qr code image, check everyting’s working fine on your metrics platform by scanning the tiny reference qr code on the upper left side of the menu!

I’d like to use my qr code with an existing marketing campaign! (trailing URL)

QRcodeLab - online qr code generator - content widgetSimply add the trailing code of your marketing campaign in the qr code content drop-down menu (“?utm” or whatever required by your online analytic tool).
Something like: “https://www.mywebshop.xyz/campaign01.html/?utm_source=december6-newsletter&utm_medium=qrcode&utm_campaign=my-first-campaign”
As those trailing data can get lengthy, consider using a URL shortener! (see “I’d like to use a short URL” topic)
As a measure of precaution and before downloading your qr code image, scan the tiny reference qr code on the upper left of the qr code content menu with your mobile phone and check if your campain settings are working correctly!

What about other “2D” matrix codes like: datamatrix, maxicode, azteccode, dotcode?

Coming soon!

Your dots / targets design do not suit me!

I lost the image I just downloaded!

retrieve image menuWe do not store your images on our servers!
But you can recover your last downloaded image you created. It is available in your browser data and you can access it through your account menu, entry ‘Retrieve previous image’.
Be aware this works only while your current user session remains active (same machine, same browser and same user session). Locally stored data using the browser cache are deleted at logout!

I’d like to create an image with a resolution higher than 4096 pixels!

Sorry, a higher size than 4096px is not possible at present time with our QrcodeLab online qr code generator.
Workaround: try to upload only a portion of the original image. Once you managed to place your qr code,  perform a download of the resulting image (preferably in png image format).
Then use an image editor (like Gimp) to re-compose the entire image with the downloaded image portion containing the qr code.
support iconOtherwise, contact us for an offer through our webapp integrated support.

Can I place several qr codes on the same image?

At present time… we don’t provide such a functionality in our online qr code generator!
But you can achieve this goal through an iterative process, each time downloading the resulting image with an additional qr code (preferably in png image format) and uploading again to add another qr code.
support iconFor special needs, contact us for an offer through our webapp integrated support.

Can I process image collections at the same time?

Not yet! Feature coming soon!
