Thermal Label Maker — Free 4×6, 4×4 & 4×3 Label Generator

Thermal labels in 3 steps

No design skills, no margins to fight — pick a size and print.

Pick your thermal size

Choose a 4×6, 4×4 or 4×3 inch slip, then add your product details and a barcode — FNSKU, FSN, EAN or SKU. Or open Bulk Import to make a whole batch at once.

Choose a template

Pick one of four templates. The label is sized exactly to your slip and a scannable CODE 128 barcode lands on every one.

Print to your thermal printer

Download a print-ready PDF sized to the slip and print one label per slip on any direct-thermal printer — Rollo, TVS, TSC, Zebra — or print to A4 and cut.

Thermal labels go wrong for small, fixable reasons

A label sized for the wrong slip, content that runs off the edge, or a barcode that won't scan wastes rolls and slows dispatch. This tool sizes everything to your exact slip before you print.

Wrong slip sizeLabels scaled to the wrong size get cut off or leave gaps. Output is sized exactly to your 4×6, 4×4 or 4×3 inch slip.
Content runs off the edgeLong names and extra fields spill past the label. Everything is laid out to fit cleanly inside the slip.
Unscannable barcodeA blurry, low-DPI barcode fails at intake. Here every code is a crisp, vector-clean CODE 128.
Faint or smudged printHigh-contrast, print-ready output stays sharp on direct-thermal paper — no faded text or smeared bars.

Everything a thermal label needs

Built for sellers, warehouses and anyone with a thermal printer.

4×6 / 4×4 / 4×3 sizes

Three standard direct-thermal slip sizes. 4×6 is the shipping and FBA standard; 4×4 and 4×3 suit smaller items. Each label is sized exactly to the slip.

Scannable CODE 128 barcode

Add an FNSKU, FSN, EAN or SKU and it becomes a crisp CODE 128 barcode, rendered sharp at the slip's exact size so it scans first time.

Any thermal printer

Works with any direct-thermal label printer — Rollo, TVS, TSC, Zebra and more. The PDF is sized to the slip, so one label prints per slip with no scaling.

A4 fallback

No thermal printer yet? Switch to an A4 layout and lay 6, 9 or 12 labels on a sheet to cut — same labels, ordinary printer.

Bulk import at scale

Generate labels for an entire batch in one pass — hundreds of items turned into print-ready thermal labels without retyping.

Saved label history

Frequently asked questions

Is the Thermal Label Maker free?

Yes. You can design labels, add the barcode and preview every page for free, with no watermark. The standard 4×6 thermal slip is free; the 4×4 and 4×3 sizes, all four templates and bulk import are part of Pro. Free accounts can export up to 10 times a day.

Which thermal sizes can I make?

Three sizes: 4×6, 4×4 and 4×3 inch. 4×6 is the standard shipping and FBA slip; 4×4 and 4×3 suit smaller items. Each label is sized exactly to the slip you pick.

Which thermal printers does it work with?

Any direct-thermal label printer — Rollo, TVS, TSC, Zebra and similar. The PDF is sized exactly to your slip, so it prints one label per slip with no scaling or margins to fight.

Do I need ink or toner?

No. Direct-thermal printers use heat on thermal paper, so there's no ink, toner or ribbon to buy. That's what makes thermal labels cheap and fast to print at volume.

Can I print on a normal A4 printer instead?

Yes. Switch to an A4 layout and lay 6, 9 or 12 labels on a sheet to cut. It's a handy fallback if you don't have a thermal printer yet.

Will the barcode scan from a thermal print?

Yes. Every barcode is a crisp, vector-clean CODE 128 rendered sharp at the slip's exact size, so it scans first time at fulfilment centres and warehouses.

Does it work for Amazon FBA and Flipkart labels?

Yes. It's marketplace-agnostic — add an FNSKU, FSN, EAN or SKU as the barcode and print a 4×6 thermal slip for any marketplace, or switch sizes as needed.

Does my product data get uploaded anywhere?

No. Labels are generated entirely in your browser, so your product details never leave your device. Saved labels are stored only in your own account history when you're signed in.
