Quick summary: Genius Scan is an excellent business scanner if you need automated exports into enterprise cloud services like Box, Dropbox, or OneDrive. Choose img2pdf if you want a 100% free app without subscriptions where OCR text extraction, PDF encryption, and file compression are completely unlocked.
Overview: Mature Cloud Archiving vs Lightweight On-Device Simplicity
Genius Scan has been a mainstay on the iOS App Store for over a decade. Built by French development studio The Grizzly Labs, it is widely praised for respecting user privacy and performing image processing locally on device. However, access to key features such as optical character recognition (OCR), auto-upload to cloud destinations, and PDF encryption requires purchasing Genius Scan+ or subscribing to Genius Cloud.
img2pdf takes a focused, free approach: all capabilities—including on-device OCR, compression size estimation, password encryption, and redaction—are included without in-app purchases or subscription paywalls. Here is how the two compare in detail.
