PDF Label Resizer
Preview original and resized PDF label pages before applying 4x6, 4x4, A6, or custom print sizes to shipping labels, FBA carton labels, and warehouse labels.
Batch PDF upload is supported. The page previews the first file and first page before applying the settings to all pages.
Keeps the full page content inside the target size. White margins may appear.
The preview uses page 1 of the first file. When you apply, the current settings are used for every page in every file.
Preview first, then resize PDF labels for the right print size
Shipping labels, Amazon FBA carton labels, and warehouse labels are often exported in a size that does not match the label paper on hand. This tool previews the original page and output page before resizing PDF labels to 4x6, 4x4, A6, or a custom size, reducing print scaling, white margins, and accidental cropping.
If an FBA carton label is exported as 4x6 but the warehouse only has 4x4 label paper, preview the crop result first, then apply it to the PDF.
Resize PDF shipping labels to common 4x6 label paper and avoid printer auto-scaling issues that shift barcodes, addresses, or notes.
Spot-check pages from the first file, then apply the same settings to every page and every file, with PDF or ZIP download.
How to choose a processing mode
Keeps the full label content visible. Use this when you do not want to crop barcodes, addresses, SKU notes, or other details. White margins may appear.
Aligns content to the top and crops overflow at the bottom. Useful for cropping 4x6 labels, FBA carton labels, or PDF labels to 4x4.
Fills the target paper size. Use this when the label should occupy the whole page, but check the preview because edges may be cropped.
