QR Code Generator & Scanner
Generate QR codes for URLs and text, or scan existing QR codes using your camera or by uploading images.
Use this tool directly in your browser without installing software or signing in.
- Create QR codes
- Bulk table rows
- Camera & image scan
- PNG, ZIP & label PDF
Center Logo
Uses a high error correction level and adds a white margin behind the logo. If the logo is too complex, the recognition rate may drop on some cameras.
Real-time Camera
Prioritizes the rear camera after obtaining user permission over a secure connection (HTTPS). When a QR is found, it immediately stops the camera and analysis operations.
Photo Scan
Large images are downscaled to a maximum of 2200px within the browser, and it also attempts to find the QR by inverting bright and dark colors.
How do I find the link from a QR code inside a photo?
Enter the link or sentence to embed in the QR and check the preview. If there's a typo in the link, the QR will lead to the wrong address even if generated successfully. After changing the logo and color, it's best to rescan it at the actual size and against the intended background.
The reading feature shows the content inside the QR; it does not judge the safety of the linked site. Verify the address and destination before opening the link. For QRs to be printed, please check them with a printed sample on paper as well.
Examples and Selection Help
Review sequence: Check spelling of input address → Generate PNG → Scan with phone → Scan at actual print size and background. Retain the bulk auto-redecoding validation but do not expand it to a guarantee of scanning in all environments.
Frequently asked questions
Does it also check the safety of the QR URL?
No. It merely displays the QR data and does not guarantee the safety of the linked site.
When is the camera permission used?
Permission is requested only when the scan via camera button is pressed. The camera track is immediately stopped upon scan completion, turning off the camera, switching tabs, or closing the page.
Which table files can create QR codes in bulk?
It reads XLSX, XLSM, XLS, XLSB, SpreadsheetML XLS and CSV files, then creates one QR code for every data row in the selected sheet.
Are generated QR codes checked for readability?
Yes. The final PNG, including a logo or transparent background, is decoded again and accepted only when it exactly matches the original payload.
Are tables or QR results uploaded to a server?
No. Table reading, QR creation, ZIP, label PDF and report generation happen in the current browser without modifying the source file.
Can I change the address inside the QR after making it?
The generated image contains the content from when it was made. If the content changes, you must create and replace it with a new QR image. Do not instruct that this tool provides redirection management features for linked servers.
It scans well on the screen, but poorly on the printout.
Check if it was printed too small, or if margins, backgrounds, or logos overlap with the code. Print a sample at the actual intended size and scan it multiple times.
