QR codes often arrive inside messages, emails, websites or screenshots on the same device you are using. Instead of pointing the camera at another screen, save or capture the code and scan the image itself.
Choose the screenshot or photo
Open SizeFix QR Scanner and choose the saved image. The decoder reads the pixels in your browser and looks for the square QR pattern. If it finds a URL, the result is shown as text with a link you can choose to open.
Keep all four corners visible
A QR code contains positioning markers near its corners. Cropping one side too tightly can remove information the decoder needs. Leave a small amount of blank space around the code whenever possible.
Use a sharp image
Blur is one of the most common reasons a QR code fails. If you are photographing a printed code, hold the phone steady and keep the camera parallel to the page. If you are taking a screenshot, capture the code at a size where the individual squares remain clearly separated.
Check contrast
Dark modules on a light background are the easiest to decode. Decorative QR codes can still work, but gradients, low contrast, logos that cover too much of the centre and textured backgrounds make detection harder. If you are creating the code yourself, test it before printing.
Screenshot scanning versus camera scanning
Use screenshot scanning when the QR code is already on your device. Use live camera scanning when the code is printed, displayed on another device or attached to packaging, signage, menus or posters. SizeFix supports both workflows from the same scanner page.
If the screenshot still does not scan
Crop away unrelated content without cutting into the code, enlarge the QR area if it is tiny, or return to the original source and capture a clearer image. Avoid editing apps that blur or heavily recompress the screenshot.
Test QR codes before sharing them
If you generated a QR code for a flyer, menu, card or sign, save the final PNG and scan that saved file before publishing it. Then test the printed version as well, because physical size, print quality and reflections can change real-world scanning behaviour.
Create and verify in one workflow
Use the SizeFix QR Generator to create the code, save the PNG, then use the scanner to verify the exact saved file. This catches destination mistakes before the code is distributed.
