Add a QR code to a PDF without making it unreadable
A QR code connects a printed or shared page to a digital resource. Reliability depends on the image, size, contrast, and clear space around it.
Steps
- Prepare a valid QR image.
- Import the PDF and choose Add QR code.
- Place it in a clear area and resize without stretching.
- Test the exported PDF on screen and in print.
Placement and quiet space
Leave white space around the code and avoid busy backgrounds, folds, or cut edges. A stable footer or boxed area makes scanning more predictable.
Test the real document
A code can work on screen and fail after reduction or printing. Scan the final output with the expected phone and verify the destination remains correct.
Insertion is local. Free output is watermarked; a clean credit or Pro removes it, but link validation remains your responsibility.
