QR codes are built for phone cameras — but often the code is already *on your screen*: in a PDF invoice, an email, a website, or a screenshot someone sent you. Pointing your phone at your own monitor to read it is clumsy and sometimes won't focus. You can decode it directly instead.

## When you'd read a QR from an image

- A supplier's invoice or a **ZATCA / e-invoice** PDF contains a QR code and you want to see what's inside it.
- A screenshot or saved image has a code and no phone is handy.
- You want to **check where a QR code leads before trusting it** — reading the URL on a computer is safer than blindly opening it on a phone.

## How image-based QR reading works

A QR reader that accepts an image looks at the picture's pixels, locates the three finder squares in the corners, reads the grid, and decodes the data — exactly what a camera does, just from a still image instead of a live feed. That means any clear screenshot, photo, or exported image works.

## For it to decode reliably

- Use a reasonably **sharp, well-lit** image — heavy blur or glare defeats it.
- Include the **quiet zone** (the blank margin around the code); cropping too tight can break decoding.
- Make sure the whole code is in frame and not cut off.
