How can we help?
Clear answers about creating, scanning, editing and exporting linear barcodes. This page has no form and does not collect your message.
Scan with the camera
Open the scanner from the main screen, allow camera access and place the entire barcode inside the frame. Recognition runs on your device. Even lighting and a steady camera improve the result.
Edit and verify
The editor lets you adjust colors, background, bar height, edge spacing and the readable number. Verification checks the structure and estimates contrast on a five-point scale; it is a practical check, not laboratory certification.
Export and share
JPEG can be exported without watching an ad. PNG, SVG, PDF, EPS and TIFF become available after an optional rewarded ad. If an ad is unavailable, try again later or use JPEG. SVG, PDF and EPS preserve vector barcode geometry for compatible editors; Android controls where a file is saved and which app receives it.
What to include in a report
Tell us your phone model, Android version, BAR Line Lab version, barcode standard and what happened. Screenshots help, but remove confidential barcode values first.
