在瀏覽器中即時、私密地掃描條碼。無需上傳伺服器，100%免費且無需安裝任何應用程式。
Open your device camera for physical barcodes or upload a screenshot/photo from your image gallery.
Point your camera at the barcode or crop closely around the code in your uploaded picture.
View your decoded text or website URL instantly. Copy with one click or export your scan history to CSV.
Unlike conventional online scanners that send your uploaded photos or camera streams to remote servers, Offline Barcode Reader processes 100% of image pixels directly inside your device memory. Your photos never leave your smartphone, tablet, or computer.
將禮品卡照片上傳至外部伺服器可能導致條形碼外洩。本地解碼確保您的禮品碼100%安全私密。
Boarding passes and event tickets encode passenger names, booking reference numbers, and access tokens. Serverless scanning ensures your sensitive travel itinerary and identity details are never stored or transmitted.
Scanning Wi-Fi access codes or 2FA authentication setups locally prevents network passwords and secret keys from being sent across remote endpoints.
Instantly check UPC and EAN retail product codes or Code 128 shipping package barcodes without installing heavy mobile apps.
