Free 4K QR code generator with transparent background

A QR code (Quick Response code) is a two-dimensional barcode readable by any smartphone. In seconds, it redirects to a website, social media profile, restaurant menu, digital business card or any other online content.

Our generator creates static QR codes: data is encoded directly in the image, without an intermediary server. Your QR code works indefinitely, even if our site goes offline. No personal data is collected or transmitted.

You can export your file as HD PNG up to 4K, choose your colors, and enable a transparent background to easily integrate the QR code on a poster, flyer, invitation or web layout.

For your events

Weddings, birthdays, inaugurations: place a QR code on your invitations or printed materials to redirect to a photo album, online gallery or RSVP form.

For your business

Restaurants, shops, artisans: display a QR code on your windows, menus or business cards to give instant access to your website, Google reviews or social media.

Why choose a 4K export?

A 4K QR code stays sharper when printed, especially on wedding materials, welcome panels, menus, table stands or large format cards. It's the right choice if you want a clean result and comfortable scanning.

When to use a transparent background?

Transparent background is ideal if you want to place your QR code on an already designed visual. This allows integrating the code on an invitation, photo, poster or frame design without adding an unnecessary white block.

Frequently Asked Questions

How do I use this QR code generator?

Enter a URL or text in the provided field, adjust the export quality if needed, choose your colors, then download the PNG once the preview is generated.

Why is the Download as PNG button disabled?

The download remains disabled as long as no URL or text has been entered. Once you type valid content, the QR code preview appears and the PNG button becomes active.

Which export quality should I choose?

1K is sufficient for simple screen use. 2K is a good balance for most needs. 3K and 4K are better suited for printing or sharper exports.

Can I customize the QR code colors?

Yes. You can change the QR code color and its background color before downloading. To ensure reliable scanning, maintain strong contrast between the pattern and the background.

Will my QR code work long-term?

Yes, as long as it is a static QR code containing an unchanged URL or text. If the entered web address ceases to exist, the QR code will still redirect to that same address, but the destination will no longer respond.

Can I use this QR code for professional purposes?

Yes. You can use the generated file on a business card, menu, poster, flyer, packaging or any other professional material.

How do I create a QR code for a wedding or invitation?

Add the URL of your gallery, film or RSVP page, choose a 4K PNG export if you're printing, then enable the transparent background if you want to integrate the QR code directly into your invitation design or wedding stationery.
