4×6 label converter
Thermal printers want one thing: an exact 4×6 inch page. Carriers and marketplaces hand you everything else — Letter-size printouts with two labels stacked on one sheet, landscape PDFs that print sideways, oversized pages with huge white margins. This converter normalizes all of it into clean 4×6 pages.
What each mode does
Fit whole page
The entire source page is scaled as large as it can go onto 4×6 paper, centered. Landscape pages are rotated 90° first (toggle it off if your printer feeds sideways). Best for single-label PDFs from USPS, UPS, FedEx and marketplace dashboards.
Split 2-up sheet
The classic marketplace layout: one portrait Letter/A4 page with two stacked labels. Split mode cuts the sheet in half and gives you two separate 4×6 pages — one per shipment — ready to print in a single job.
Batch conversion
Add as many PDFs as you like before pressing Resize. Output is a single merged 4×6 document in file order — perfect for an end-of-day print run. Need them separate? Convert one file at a time.
