A4 TO 4×6 CONVERTER

Turn the label on an A4 page into a clean 4×6 PDF.

Carrier and marketplace downloads often place one label on a full sheet. LabelCheckup finds the useful area and rebuilds it at thermal-label size.

02 / DIAGNOSIS

Why normal print scaling fails

01

Fit to page can shrink a small label even further.

02

Printing the entire sheet wastes label stock or plain paper.

03

Cropping by eye can remove a barcode quiet zone.

04

Screenshots replace sharp PDF vectors with lower-quality pixels.

03 / WORKFLOW

From source PDF to a print-ready label

1

Upload the A4 PDF

The page is rendered locally and its dense label region is detected.

2

Choose 4 × 6 inches

Confirm the crop and select 203 or 300 DPI to match the printer.

3

Print the new PDF

Use Actual size or 100%. Disable Fit, Shrink oversized pages, and margins.

04 / FAQ

Questions before you print

Will the converter stretch my label?

It fits the crop to the selected physical size. A warning appears when the crop ratio differs enough to risk visible distortion.

Which size should I choose?

Use 4×6 for 101.6×152.4 mm media, 100×150 mm for metric stock, or A6 for 105×148 mm sheets.

Can I convert a Letter-size PDF too?

Yes. The tool works from the detected label area rather than relying on the outer page size.
