Label size and conversion guide

4 × 6 in is 101.6 × 152.4 mm, not 100 × 150 mm. At 8 dpmm these are 813 × 1219 and 800 × 1200 dots; at 12 dpmm, 1219 × 1829 and 1200 × 1800 dots. Choose the actual media and printer density.

Crop coordinates refer to the original page. The crop is rotated, fitted to the selected label, then thresholded. The output is a compressed bitmap (^GFA Z64), not editable text. Start with a single page and inspect the result before processing the rest.

PDFs stay in your browser; rendered page images are uploaded for conversion. A batch has at most 50 pages. Cancel preserves completed pages; retry only failed or cancelled pages. Changing the file or settings clears the old results. A partial download contains only successful pages.
