This tool only changes tones. It cannot repair a damaged barcode, and we cannot guarantee a barcode will scan, so test-print before shipping.
How to use the Shipping Label Enhancer
- Drop a label image or PDF.
- Adjust the brightness and contrast, or choose grayscale or black and white with a threshold.
- Compare it with the original, then download it and test-print.
A faint scan or a photo of a label can often be made easier to read by raising the contrast. Thermal printers print only black or white, so a clean black and white version can also print more predictably than a grey one.
The tool only adjusts tones. It does not repair damaged labels, redraw barcodes or change any text, and a threshold set too far can erase thin lines. We cannot guarantee that a barcode will scan after any image change, so print a test label and scan it before you ship. Your carrier’s rules always take priority.
