Resize shipping label to 4x6 online free

Quick answer
- Use the converter when the label is inside an A4 or Letter PDF page.
- Do not resize a file that is already true 4x6, 6x4 or 100x150mm.
- Print the converted PDF at Actual Size or 100 percent scale.
- Use the original PDF instead of screenshotting the barcode into Word.

When to resize a shipping label to 4x6
Resize the label when the label graphic 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 or get clipped.
If the PDF is already a true 4x6, 6x4 or 100x150mm page, do not resize it again. Print it at Actual Size with the matching paper preset. If you are unsure, use the shipping label size checker before converting.
Check the source PDF before resizing
Open the original PDF and look at the page, not just the label graphic. If there is office-paper space around the label, it likely needs a crop or resize before it reaches a thermal printer. If the label fills a small page, focus on printer scale and calibration instead.
The safest path for one-off files is to start with the original PDF, convert it to a real 4x6 page, then print one test label. The crop shipping label PDF workflow explains the PDF-first process if you need the detailed version.
Print settings after resizing
After downloading the resized PDF, set your printer paper size to 4x6 inches, 6x4 inches or the closest 100x150mm preset. Use Actual Size, 100 percent or no scaling for the converted file.
If the output still prints too small, enlarged or clipped, check the active driver preset before changing the crop. The shipping label print scale calculator and 4x6 settings checker can separate a PDF-size problem from a printer-setting problem.
Avoid screenshot resizing
Screenshotting a label, pasting it into Word and dragging it to roughly 4x6 can make the address look acceptable while the barcode gets softer. A PDF resize keeps the label closer to the original source file and avoids another manual scaling step.
If your barcode already looks soft or fails to scan, use the blurry shipping label barcode checker before printing a batch.
When to use LabelChop automation
The free resize tool is useful for one-off PDFs. 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.

How do I resize a shipping label to 4x6?
Upload the original A4 or Letter shipping-label PDF, choose the label position, then download a new 4x6 / 100x150mm PDF for your thermal printer.
Can I resize a shipping label to 4x6 online for free?
Yes. The first useful conversion is free. It is best for one-off carrier, marketplace or ecommerce PDFs that are too large for a 4x6 printer.
Should I resize a shipping label that is already 4x6?
No. If the PDF page is already 4x6, 6x4 or 100x150mm, print it at Actual Size with the matching paper preset instead of converting again.
Does the converter store my uploaded PDF?
No. The converter processes the uploaded PDF to return the resized file and does not save your shipping-label PDF.
When is LabelChop better than this free resize tool?
