Scan with the camera
Open the Scan tab and point the camera at a barcode. If the camera is unavailable, check camera permission in system settings and make sure no other app is using it.
Import images, PDFs, or screenshots
Use the photo or file import action to recognize barcodes from selected images, screenshots, or PDF pages. If nothing is found, try a clearer image with the full code visible.
Generate and save QR codes
Open the Generate tab, enter text or a URL, then save the generated QR image to Photos or Files when you need to share it elsewhere.
Read and inspect results
Recognized content can be copied. Links can be opened directly. Use ASCII and HEX views when you need to inspect invisible characters or raw bytes.
