Paste QR

Paste QR helps you read QR codes from images, screenshots, and photos. Even if the original image is blurry, tilted, or low quality, the app decodes the content and recreates it as a clean, sharp QR code. You can then easily share it or open it safely. HOW TO USE THE APP Clipboard Copy an image with a QR code and the app will automatically try to read it when opened or brought to the foreground. Paste Paste an image with a QR code directly into the app. Photos Select an image from your gallery and let the app recognize the code. Camera Scan a QR code instantly when you don’t want to use a saved image. Share Send an image to Paste QR from another app using the share extension or action—no need to save it to Photos first. WHAT THE APP CAN RECOGNIZE Paste QR supports common web links, App Store links, phone numbers, SMS messages, emails, vCard contacts, calendar events, Wi-Fi credentials, map locations, payment data (including SPAYD format), cryptocurrency addresses, and plain text. SAFER LINK OPENING For web URLs, the app evaluates basic risks and can warn you before opening a link, so you know where it leads. This gives you better control over what actually opens when you tap. TAKE ACTION INSTANTLY After recognizing content, you can often act right away: open a link, connect to Wi-Fi, save a contact, compose an email, or make a call. The app turns scanned QR codes into useful actions, not just displayed text. BUILT FOR EVERYDAY SITUATIONS Paste QR is ideal when you only have a QR code as an image—like in an email attachment, chat screenshot, restaurant photo, or a picture of a projected screen. The original image doesn’t need to be perfect—just readable. Paste QR transforms it into a clean, usable format.
