Frequently Asked Questions
Why can't my barcode be read?
Blurry, low-contrast, or poorly lit images may fail. Try a clearer, well-lit photo with the barcode centered.
Are my uploaded images stored?
No. All processing happens locally in your browser. No data is ever uploaded to any server.
How accurate is this barcode reader tool?
All processing runs entirely in your browser using verified algorithms. Results are computed with full double-precision — no server-side rounding or data transmission occurs.
How does 1ClickTools ensure my privacy and file security?
Privacy is our highest priority. All computations, data parsing, and file conversions take place locally inside your web browser's client-side memory using modern JavaScript and HTML5 APIs. Your data is never uploaded, stored, or transmitted to any external remote server.
