FAQ
I changed Poshmark to 4x6 — why is my old label still letter-size?
The setting affects labels you download after changing it. A label PDF you already saved keeps its letter-size page — crop it here instead of waiting for support.
Why does my Poshmark label print across two labels?
The PDF page is 8.5×11 (letter), but the printer is loaded with 4×6 labels, so the driver splits the page over two (or more) labels. Crop the PDF to a 4×6 page here, then print with paper size 4×6 and scale 100%.
Why is my Poshmark label tiny in the middle of the page?
The 4×6 label sits on a full 8.5×11 (letter) page and the printer shrinks the whole page to fit — so the label and barcode come out small. Cropping to just the label makes it print full-size.
I already downloaded the label — do I have to buy or regenerate it?
No. Drop the PDF you already have into the tool: it crops the existing label onto a 4×6 / 6×4 page without changing its content, so you don't need to void, re-buy or regenerate anything.
Does this work for Mercari or Depop labels too?
Usually yes — choose Auto-detect and adjust the crop box if needed.
Are my labels uploaded anywhere?
No. The PDF or image is read and converted entirely inside your browser with JavaScript (pdf.js and pdf-lib). Nothing is sent to a server — you can even disconnect from the internet after the page loads and it still works.
How do I print the 4x6 PDF correctly?
Open the downloaded PDF, choose your thermal label printer, set the paper size to 4×6 in (100×150 mm) and the scale to 100% / "Actual size" (not "Fit to page"). Then print.
Is it free?
Yes. Converting one label at a time is free with no watermark and no sign-up. A Pro option for merging many labels into one PDF is planned.
