PDF to 4x6 label converter online free
Convert A4 or Letter shipping-label PDFs into clean 4x6 / 100x150mm files for thermal printers. Useful for carrier, marketplace and ecommerce PDFs that are too big for a label printer.
Quick answer
- Use this when the label sits inside an A4 or Letter PDF page.
- Do not crop a PDF that is already true 4x6, 6x4 or 100x150mm.
- Print the converted PDF at Actual Size or 100 percent scale.
- Avoid screenshot and Word workflows because they can blur barcodes.

When to convert a PDF shipping label to 4x6
Use this converter when the label is trapped inside a larger PDF page. A4 and Letter shipping-label PDFs are common in carrier, marketplace and ecommerce workflows. If you send the whole page to a 4 inch thermal printer, the label can print tiny, clipped or shifted into a corner.
Do not convert a file that is already a true 4x6, 6x4 or 100x150mm PDF. Print that file at Actual Size instead. If you are not sure what you have, run the shipping label size checker before changing printer settings.
Print settings after conversion
After downloading the converted file, open it in a normal PDF viewer and set your printer paper size to 4x6 inches, 6x4 inches or the closest 100x150mm preset. Use Actual Size or 100 percent scale for a converted 4x6 PDF.
If the converted file still prints too small, the problem is probably the driver preset or browser print dialog. Use the shipping label printing too small diagnostic or the 4x6 settings checker before wasting more labels.
Avoid screenshot and Word workarounds
Screenshotting a label can make the address look fine while the barcode gets softer. A PDF crop keeps the label closer to the original source file and avoids another resize step in Word, Canva or an image editor.
If the barcode is already blurry or fails to scan, use the blurry shipping label barcode checker before printing a batch. For a fuller walkthrough, read the crop shipping label PDF guide.
When to use LabelChop automation
The free converter is useful for one-off files. LabelChop is for sellers who keep receiving compatible shipping-label PDFs that need the same crop, resize and print workflow every shipping day.
LabelChop watches your Downloads folder, detects shipping-label PDFs, crops or resizes them into 4x6 / 100x150mm output and prints or saves the result for your thermal printer. It helps with PDFs from carrier and marketplace workflows after you have the file. It is not an official integration with those services.
Doing this more than once a week?
Convert this label free, then use LabelChop when repeated carrier or marketplace PDFs need the same 4x6 output.

Can I convert a PDF shipping label to 4x6 online for free?
Yes. Upload an A4 or Letter shipping-label PDF, choose the crop position, then download a 4x6 / 100x150mm PDF for a thermal printer.
Is this different from the A4 to 4x6 converter?
It uses the same free converter workflow, but this page is written for people searching for PDF to 4x6 label conversion rather than A4 wording.
Should I convert a PDF that is already 4x6?
No. If the PDF page is already 4x6, 6x4 or 100x150mm, print it at Actual Size or 100 percent with the matching printer paper preset.
Does LabelChop store my uploaded shipping-label PDF?
No. The free converter processes the uploaded PDF to return the converted file and does not save your PDF.
When should I use LabelChop instead of a free converter?
Use the free converter for one-off PDFs. Use LabelChop when compatible carrier or marketplace PDFs need the same crop, resize and print workflow every shipping day.
