How to print Vinted labels on a 4×6 thermal printer from your iPhone

Sold something on Vinted and want the label on a sticky 4×6 thermal label rather than A4 paper and tape? Here’s how to do it from your phone.

Updated 5 November 2026

First, check whether you need to print

Depending on the carrier and how the parcel is being sent, Vinted doesn’t always ask you to print anything. For some options you get a QR code instead, and the shop or locker prints the label for you. Vinted’s own help pages describe this for InPost, for example.

Which options you get depends on the carrier, the buyer’s choice and the drop-off point, and it changes from time to time. So check the shipping details on the sale. If a QR code drop-off is on offer and that suits you, you don’t need a printer at all.

The rest of this guide is for when you do have a label to print.

What a printable Vinted label looks like

When Vinted gives you a label to print, it’s usually a PDF laid out for A4 paper. The label itself takes up only part of the page, and there may be instructions or other text around it.

That’s fine for a home printer: print it, cut it out and tape it on. A 4×6 thermal printer, though, expects a page that’s already 4×6 inches (about 100 × 150 mm). Send it the whole A4 page and you’ll get a shrunken label, a clipped one, or wasted labels.

Save the label to your iPhone

  1. In the Vinted app, open the sale and find the shipping label. The exact wording on the screen may change, but the label is attached to the order.
  2. When the label PDF opens, use the share option and choose Save to Files. If it arrives by email instead, open the attachment and save it to Files from there.
  3. If you can only view the label and can’t save it, take a screenshot as a last resort. A PDF gives a sharper result, because a screenshot is only as detailed as your screen.

Crop it to 4×6 with Label Fixer

  1. Open Label Fixer and import the Vinted label PDF from Files, or choose a screenshot or photo from Photos.
  2. If the PDF has more than one page, pick the page with the label on it.
  3. Label Fixer finds the label and crops it to a portrait 4×6 inch PDF. Check the preview: the address, barcode and any QR code should all be inside the crop.
  4. If the crop has picked up too much, such as printed instructions beside the label, tap Edit Label. Move or resize the crop so it sits around the label, and rotate it if the label is sideways.
  5. Share the finished PDF to your printer’s own app, or save it to Files, send it by Mail or AirDrop it to a computer that’s connected to the printer.

If the label sits next to printed instructions on the page, the automatic crop can sometimes include them. Tap Edit Label and pull the crop in until only the label is inside.

Open the PDF in your thermal printer’s app, or print it from a computer the printer is connected to.

  • Choose 4×6 inch (sometimes listed as 6×4, or 100 × 150 mm) as the paper or label size in your printer’s app.
  • Print at actual size or 100%. Avoid “fit” or “scale” options unless your printer’s instructions say otherwise.
  • Do one test print when you set up a new printer or a new roll, and check the barcode is sharp, complete and not cut off at the edges.

Stick the label flat on the largest side of the parcel, and keep tape away from the barcode.

Common snags

  • The label is sideways. Use Edit Label to rotate it, so the finished 4×6 page is upright.
  • The PDF has more than one page. Pick the page with the label when Label Fixer asks.
  • The label looks fuzzy. That usually means it came from a screenshot or a compressed image. Go back and save the original PDF if you can.
  • You need it again. Reopen it from History in Label Fixer and share it again, without redoing the crop.

If you don’t have a thermal printer

You don’t need one to sell on Vinted. You can print the A4 label on any printer at 100% size, cut it out and tape it on, or use a QR code drop-off where it’s offered. A thermal printer just saves on paper, ink and tape once you’re sending parcels every week. If you’re thinking of getting one, our guide to choosing a 4×6 thermal label printer covers what to look for.
