Words from real customers
" Like many Amazon FBA sellers I have struggled with barcode issues and printing readable, scan-able labels. All of that ended when I found your service. You guys are terrific and your service rocks!!! It worked the first time without any problems. Very pleased and I will upgrade to a paid plan very soon. No one should try selling on Amazon without using your valuable web service. The browser extension is also a great add-on for speed and efficiency. Thank you "

" We were looking for a solution to put our company name and the shipment party number on the FBA product labels to distinguish our products from other sellers'. You would not believe how this unique feature helped us with our FBA returns. For extra, we were able to see and prove many more switch-bait returns with the Label Resizer. Your service is for sure a Game Changer!!. Thank you Label Resizer "

" I've been printing some shipping labels direct from Shopify.They print too small on my 4x6. I now use your software and it prints perfectly.I also love it when I get those emailed labels that never work right for my Zebra 450 label printer. With your label resizer, I get it perfect, makes it so easy and takes seconds. You've earned a spot on my bookmark bar! Thanks so much "

What is Label Resizer and what does it do?
Label Resizer is a browser-based label management tool for Amazon FBA sellers, Walmart WFS sellers, and e-commerce businesses. It generates, resizes, and enriches product labels, box labels, and shipping labels - directly inside Amazon Seller Central and Walmart Seller Center via a Chrome and Firefox extension, or through PDF and spreadsheet upload on the web. Core capabilities include FNSKU product label generation, FBA box label customization, SKU-based split shipment merging, 2D box content barcodes, warning labels, barcode generation, Amazon Transparency labels, and a custom label design tool.
Which platforms and label types does Label Resizer support?
Label Resizer works with Amazon FBA (FNSKU product labels, box labels, shipment labels, 2D box content barcodes), Walmart WFS (product and shipment labels), and 15+ shipping carriers and marketplaces including FedEx, UPS, USPS, DHL, eBay, Etsy, Mercari, Shopify, Flipkart, ShipBob, and Mercado Libre. Over 100 label types are supported for resizing and generation across these platforms.
How does the Label Resizer browser extension work?
After installing the Label Resizer Chrome or Firefox extension, a Resize Labels button appears directly on label pages inside Amazon Seller Central, Walmart Seller Center, FedEx Ship Manager, UPS Shipping Manager, and Mercari. Click the button and your labels are generated or resized with your saved settings applied - without downloading files, switching tabs, or using a separate tool. Settings configured in your Label Resizer account - label size, complete title, custom text, numbering, separators - apply automatically every time.
Do I need to install software, or does Label Resizer work in the browser?
Label Resizer is entirely browser-based - no software installation required. The web tool runs in any modern browser at labelresizer.com.

You set your preferred size once and it applies to every label you generate.
