Frequently asked questions

• What is a QR code?

  

  A QR code is a scannable pattern that stores information, most often a link. When someone scans it with a phone camera, it opens the connected page or file.

  A QR code generator helps create that pattern without manual setup, so people can access the right content faster from print or digital materials.

• How to customize a QR code?

  

  Create QR codes that match your business vibe. You can change visual settings such as colors, patterns, frames, and layout options. Keep enough contrast between the code and background, then test the scan before printing or sharing it widely. 

• How to create a QR code for a PDF?

  

  You can add a QR code for a PDF directly inside the editor, without switching to a separate tool. Open the file you want to edit, generate the code from any link, and paste it onto the page where it belongs, whether that's the cover, a sidebar, or next to a specific section. The QR code becomes part of the document, so anyone reading the PDF can scan it from the screen or print it and open the linked content on their phone.

• How long are QR codes valid for?

  

  A QR code keeps working for as long as whatever it points to is still online. If you delete the page, move the file, or lock it behind a login, the code starts leading nowhere useful.

  Before you print a code onto something permanent, scan it once with your phone and make sure it opens what you expect, especially for menus, event signage, or anything you hand to customers.

• Can I create custom QR codes on my mobile?

  

  Of course, you can turn links into QR codes in the same flow, whether you're on your laptop at home or your phone at an event. That's useful when you need to create or update a code during a meeting, presentation, or quick review.

• Can I create a QR code for a URL?

  

  Yes, that's one of the most common uses of the tool. Paste any web address into PDF Guru, and the editor will convert a link to a QR code in seconds.
