    1. Drop the PDF

    Use the file straight from the marketplace. Letter, A4 or a whole page of labels.

  2. Crop marks around a shipping label with a 4×6 tag

    2. We crop it to 4×6

    The label is found and cropped as vector artwork, so the barcode stays sharp.

Questions

Is my shipping label uploaded to a server?

No. The whole conversion runs in your browser. There is no backend, no account and no upload, so your address and tracking number never leave your device.

Does the barcode stay scannable?

Yes. The label is cropped as vector content and placed on the 4×6 page, so the barcode is never re-photographed or blurred.

What printers does this work with?

Any 4×6 label printer: Rollo, MUNBYN, Zebra, Arkscan, Phomemo, Brother. It also works on a normal inkjet or laser printer if you use 4×6 photo paper or adhesive labels.

Why does my label print tiny or off-center?

Marketplaces hand out letter or A4 pages, and printer drivers shrink the entire page onto the roll. Crop the label first, then print at 100% / Actual size with Fit to page turned off.

Can I convert a batch of labels?

A multi-page PDF converts free, one 4×6 page per label. Combining several PDFs into one print-ready file is a LabelConvert Pro feature.

Does it work on a phone?

Yes. Open the page in Safari or Chrome, pick the PDF from Files, then print the result or open it in your label printer app.
