All-In-One

Overview

All-In-One replaces half a dozen separate utilities with a single workspace. It scans QR codes and barcodes from a live camera or from photos, PDFs, and documents, generates styled QR codes and standard barcodes (EAN-13, UPC-A, Code 128, PDF417, Data Matrix and more), keeps an encrypted 2FA authenticator vault for TOTP and HOTP tokens, and builds unlimited digital profiles and multi-link pages driven by dynamic QR codes. Everything is local-first with IndexedDB and no sign-up required to scan, so it keeps working offline on any device.
