If you sell on Flipkart, Amazon, or Meesho, you know the format: every order downloads as a PDF with the shipping label crammed onto the same page as a tax invoice, or stacked one after the other. Your thermal printer wants a clean 4×6 label and nothing else. Cropping each one by hand — especially across a batch of fifty orders — is exactly the kind of repetitive work that eats an afternoon.
Auto-cropping does it in one pass: feed in the raw download, get back just the labels, sized for your printer. This guide covers the bulk workflow, the print and output options, and how it differs from pulling out the invoices instead.
Before you start
A couple of things worth knowing first:
- Upload the original PDF straight from the seller panel. Don't pre-crop or edit it — the auto-crop reads the platform's standard layout to find the label, so the cleaner the input, the better the detection. Bulk upload is supported, so drop in the whole day's orders at once.
- Know which printer you're feeding. A 4×6 thermal label printer and a regular A4 office printer want different output. You'll pick this in the tool (covered below), so have it in mind before you start.
The steps
Open Blackpdf's Auto-Crop Labels tool and drop your PDFs in. You can select multiple files at once for a whole batch.
Pick what you're printing on under "Print for":
- Thermal — one label per page, sized for 4×6 thermal printers. This is what most sellers want.
- Normal (A4) — laid out for a standard office printer.
Choose your Output:
- Single merged PDF — all the cropped labels in one file, ready to send to the printer in a single job.
- Separate PDFs — each label as its own file, useful if you need to handle orders individually.
Click Auto Crop Labels. The tool finds the label on each page, drops the invoice portion, and assembles the result.
Download and print.
Tip: if you process orders from one platform every day, there are platform-tuned versions that know each layout exactly — Amazon, Flipkart, and Meesho. They skip the guesswork for that platform's specific PDF.
Common questions
Which marketplaces does this work with?
It's built for the standard shipping PDFs from Flipkart, Amazon, and Meesho, and handles similar e-commerce label-plus-invoice layouts. For the cleanest results on a single platform, use its dedicated version: Amazon labels, Flipkart labels, or Meesho labels.
What happens to the tax invoice on the page?
When you crop labels, the invoice portion is dropped — you keep only the labels. If you need the invoices instead (for GST records or accounting), use the Auto-Crop Invoices tool, which does the opposite: keeps the tax invoice and discards the label.
Can I crop a whole batch of orders at once?
Yes — bulk upload is supported. Drop in all the order PDFs together and choose Single merged PDF to get one print-ready file for the whole batch.
My labels print too big or get cut off. What's wrong?
That's usually a Print-for mismatch. If you're on a 4×6 thermal printer, pick Thermal; if it's a regular printer, pick Normal (A4). Then make sure your printer dialog isn't re-scaling — set it to print at 100% / actual size rather than "fit to page."
Is there a limit on how many orders I can process?
The tool is free for all users and supports bulk uploads. For very large batches, splitting them into a few uploads keeps each pass fast.
Wrap-up
The flow is short:
- Drop your seller-panel PDFs into Auto-Crop Labels — bulk is fine.
- Pick Thermal or Normal (A4) under Print for.
- Pick Single merged PDF or Separate PDFs.
- Click Auto Crop Labels and print.
If you need the tax invoices off those same PDFs rather than the labels, that's the Auto-Crop Invoices guide. And if you sell mostly on one marketplace, the platform-tuned versions for Amazon, Flipkart, and Meesho are the fastest route.
